Description
Introduction
This project is related to a simulation of a wind tower system with qanat using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
This system is included in the category of passive ventilation methods. In passive ventilation systems, no mechanical device is involved.
Generally, passive ventilation systems are included in two groups, which are wind-driven and buoyancy-driven. In the wind-driven method, the pressure difference is the factor of air circulation, and in the buoyancy-driven method, the density difference leads to natural convection heat transfer.
The wind tower ventilation system with qanat is placed in the hybrid passive ventilation group (a combination of two groups).
The wind tower system with qanat is one of the traditional ventilation systems based on the architecture of old buildings. This system was very popular in dry and hot areas.
In this system, a tall wind tower is placed on top of the building, and an underground cooling system is considered. In this project, we are using qanat as an example of a common underground cooling system.
When a large structure faces the wind flow, a significant pressure difference appears on its two sides. In front of the structure is a high pressure, and behind it is a pressure vacuum, which leads to air suction caused by the pressure difference.
On the other hand, inside the cooling system or qanat channel, cold water is up to a certain level. The free wind flow enters the channel, and after hitting the water surface, it cools and moistens. This cool air enters the interior of the building from the floor and performs the air conditioning process.
In this problem, the free hot air flow enters the cooling channel with a velocity of 0.2 m/s and a temperature of 300 K. To simplify the problem; we avoided modeling the water level inside the channel and used the constant temperature boundary condition. We assumed that the wall of the underground channel has a constant temperature of 278 K.
We have also modeled some windows on the walls of the room. These windows are exposed to sunlight and in contact with the hot air of the outside environment. So we have assumed that the glass windows have a constant temperature of 298K.
We designed the geometry of the model using Design Modeler software. The current model includes three parts: room, tower and underground channel.
Then we meshed the model using ANSYS Meshing software. The meshing is unstructured, and the number of created cells equals 402198.
Wind Tower Methodology
Using ANSYS Fluent software, we numerically simulated this model according to computational fluid dynamics (CFD). This problem is independent of time and steady state, and the solution is based on the pressure-based solver.
As we said, natural convection heat transfer also happens in this problem. Natural convection is created based on the buoyancy effect. This means that changes in temperature cause changes in density. Warm air is lighter and less dense and rises upwards.
Therefore, the current system is useful for the exit of hot air. The entry of cool air from the floor of the room and the air suction from the exit panel of the tower helps the exit of hot air.
We do not consider the air density constant to apply the buoyancy effect. The relation between density, pressure, and temperature according to the ideal gas law is used in the incompressible ideal gas model. Note that the density is dependent on the operating pressure and is independent of the local relative pressure. So assuming constant pressure, density becomes a function of temperature.
Wind Tower Conclusion
After the simulation, we obtained 2D and 3D temperature, pressure and velocity contours. We also obtained 2D and 3D velocity vectors.
The temperature contour shows well the cooling process inside the room. Cool air enters the underground channel, and hot air exits from the tower panel.
The pressure contour also shows the pressure difference well. The high pressure of the external air and the low pressure inside the room and tower cause hot air to be sucked out.
Velocity vectors show the direction of air movement inside the room and tower well. Cool air enters the room at high speed from the floor, and after full circulation in the room and air conditioning, it leaves through the tower.
So we conclude that we perform the simulation correctly. The passive ventilation system of the wind tower and qanat perform the air conditioning operation correctly.

Prof. Hope Block III –
I really appreciated the thermal management concept in the simulation. Could you explain more on how the cooling effect within the qanat enhances the overall system’s efficiency?
MR CFD Support –
Certainly! The qanat acts as an underground channel that provides a cool surface through its constant temperature walls. As the hot wind enters the tower and reaches the qanat, it interacts with this cooler surface and transfers heat to it, thereby reducing the air temperature due to the heat exchange process. As this cooler air then moves into the interior of the building, it helps in lowering the overall temperature. The efficiency of the system is tied to the temperature difference between the ambient hot air and the cooler surfaces of the qanat, and the capacity of the qanat to maintain this temperature gradient despite the continuous air supply. Essentially, the qanat’s ability to consistently present a cooler boundary to the incoming warmer air is what enhances the system’s efficiency in terms of passive cooling.

The simulation of a wind tower with qanat in ANSYS Fluent seems fascinating! How effective is this traditional system compared with modern air conditioning in terms of energy efficiency?
MR CFD Support –
Thank you for your interest in the wind tower with qanat simulation. Traditional systems like the wind tower with qanat are indeed fascinating. In terms of energy efficiency, these systems are highly effective as they use natural forces like wind and thermal buoyancy instead of electrical energy to function. They are passive systems, so their operation cost is significantly lower than that of mechanical air conditioning systems. While they may not always match the cooling capacity of modern air conditioners, they are environmentally friendly and sustainably manage the interior climate, particularly in the regions for which they were designed.

Miss Therese Medhurst –
I’m fascinated by the wind tower and qanat system described. Could you elaborate on how the constants for the temperature of the underground channel walls and the glass windows were determined?
MR CFD Support –
In this simulation, the temperature constants are typically chosen based on average expected conditions or specific design requirements. The constant temperature of the wall of the channel at 278 K represents a typical temperature of soil or underground environments in certain geographical locations. The glass windows having a constant temperature of 298 K could be based on the average temperature observed due to solar heat gain in that local climate. In order to set the boundary conditions appropriately, these constants are chosen in such a way that they best represent the physical system being modeled.
Mallory Kessler –
The description very thoroughly explains how the system functions. The addition of temperature assigned to the glass windows sounds like an intricate detail strengthening the simulation realism.

Alanna Welch –
I’m fascinated by the traditional wisdom behind these structures! Can you share any insights on how well the simulation aligned with the historical data on wind towers and qanats efficiency?
MR CFD Support –
In the MR CFD simulations, we strive to closely replicate historical designs and their operational efficiencies as much as possible. While the simulations are informed by the fundamental principles of the original systems, evaluating how closely the simulation aligns with historical data would typically require direct comparison with empirical data from real-world wind towers and qanats. Since this detail isn’t provided, such a comparison isn’t specified. However, the simulation’s results should provide good insights into the operational efficacy of the modeled structures from a theoretical perspective.
Heidi Pollich –
The results of the simulation sound effective. Was the humidity frontier monitored, given that the air flow first hits the water surface in the system?
MR CFD Support –
In this simulation, the humidity condition is not explicitly monitored as the project simplifies the problem by avoiding the modeling of water levels in the channel. Instead, it assumes a constant temperature of the underground channel’s wall to represent the cooling effect of the qanat. Therefore, the air’s moisture increase after contact with water isn’t part of the analysis.
Ebba Legros –
I’m impressed by how this ancient architecture has been modeled for modern analysis. Is the assumption of the windows having a constant temperature of 298K made for simplicity, and can this be adjusted through parameter studies for more accurate real environmental interaction effects?
MR CFD Support –
Thank you for your interest in our simulation training. Yes, the constant temperature assumption for the window was done to simplify the analysis for a steady-state condition. However, we certainly can adjust and perform parameter studies to take into account the varying environmental conditions and achieve even more accurate representations of real world effects. We can simulate different external temperature scenarios to see how this affects the system performance.
