Description
Radiation Heat Transfer in a Computer Room CFD Simulation, ANSYS Fluent Training
In this project, the air conditioning of a computer room containing four computers is simulated by ANSYS Fluent software.
The present model consists of a computer room with different heat sources. The present model is designed in three dimensions using Design Modeler software.
Since the geometry is symmetric, only one-quarter of the geometry is modeled. This quadrilateral geometry consists of two sloping glass and steps carrying water flow.
The meshing of the model has been done using ANSYS Meshing software. The element number is 809037.
CFD Methodology
In this project, steady airflow enters the domain from the bottom of the room by several inlets and leaves the domain from several outlets on the ceiling, considering Radiation heat transfer.
This new air conditioning method is commonly used in office environments. This method provides more energy efficiency since the flow naturally goes upwards due to density difference and buoyancy body force.
Fresh air enters the computational domain with a velocity of 0.61254m/s and a temperature of 291.8K. One of the room’s four main walls is exposed to a constant heat flux equal to 194 W/m2. The other heat sources include a laptop and a simulator with heat fluxes equal to 153.25 and 90.56W/m2, respectively.
A realizable k-epsilon model is used for solving turbulent fluid equations. The energy equation is enabled to calculate temperature change within the domain, and the ideal gas model is used to account for air density change due to temperature change.
Most importantly, the Surface to Surface (S2S) model is exploited to simulate the radiative heat transfer inside the computational domain.
Radiation Heat Transfer Conclusion
The mixture mass flow rate at the Computer room outlet is 0.568 kg/s. The air density has the minimum value on surfaces that heat flux is applied to due to increased fluid temperature, density decreases, and upward buoyant force affects the fluid volume.
It can be seen that the higher we go along room height, the less air density is observed. High temperatures equal to 327 k are observed on laptop surfaces and hot walls.
Extreme turbulence can be seen on the hot wall and the top of the simulator’s head. The reason is the consideration of high heat fluxes for laptops, simulators, and hot walls.

Prof. Alex Hayes Sr. –
I’m thrilled with the detail of simulation! But could you please explain if it’s possible to run this kind of simulation with lower-quality mesh and still get accurate results?
MR CFD Support –
Thank you for your positive feedback! In CFD simulations, mesh quality is critical for accuracy, however, some simulations can be run with a coarser mesh if they have larger tolerances for error. The trade-off with a lower-quality mesh is a potential decrease in result precision, particularly in areas of high gradient like near heat sources. It’s important to perform a mesh sensitivity analysis to understand how mesh quality affects your simulation. Rest assured, if the results’ accuracy is less crucial for certain studies or if computational resources are limited, a coarser mesh could be used with careful considerations.

Mollie Zieme –
I was very impressed with the detailed setup for the computer room’s radiation heat transfer simulation. The integration of multiple heat sources along with airflow and the use of the Surface to Surface model for radiation made it quite comprehensive. How does the density variation due to temperature change affect the overall airflow pattern in this simulation?
MR CFD Support –
In this simulation, the temperature rise causes air density to decrease near the heat sources due to the ideal gas behavior. This reduction in density generates buoyancy forces, which cause the air to rise. As the warmer, less dense air rises, cooler, denser air is drawn in through the inlets at the bottom of the room. This natural convection cycle helps distribute the air within the room, thereby impacting the airflow patterns and contributing to the efficiency of the air conditioning system.

It helps achieve a more accurate prediction of thermal comfort and energy efficiency.

Willy Fisher –
I wasn’t clear on this from the overview—how exactly did the S2S radiation model influence the airflow patterns in your simulation?
MR CFD Support –
The Surface to Surface (S2S) radiation model accounted for the transfer of thermal radiation between surfaces within the computer room. Since thermal radiation can affect the temperature distribution on solid surfaces—warmer surfaces can heat the adjacent air—it influences the natural convection currents within the room. Radiative heat transfer might increase the temperature of the air in contact with heated surfaces more significantly than the other regions, reinforcing the buoyancy effects and altering the overall airflow patterns. Thus, the vertical temperature gradient and the resulting flow of air upwards are more pronounced.
