Description
Boiling inside a Nanotube CFD Simulation by ANSYS Fluent, Training
The present problem simulates the boiling process inside a nanotube using ANSYS Fluent software.
A nanotube is a tube that is made at the nano-scale by nano-particles. This type of tube’s diameter can be about a few nanometers, While its length can reach several millimeters.
This simulation assumes that the water saturation temperature is 383.15 K; at this temperature, a phase change from liquid water to water vapor occurs.
The water stream enters the pipe at a speed of 1e-5 and a temperature of 373.15 K, and since this water stream is close to the saturation temperature, it can be said that it is ready for the boiling process.
The present model is designed in two dimensions using Design Modeler software. The model is a nanotube drawn in two dimensions due to its symmetrical geometric structure and reduced computational cost.
This pipe is of nanotube type and has a length of 0.00005 m and a radius equal to 0.00000015 m.
We carry out the model’s meshing using ANSYS Meshing software, and the mesh type is structured. The element number is 100000.
Boiling Methodology
It is assumed that the pipe wall has a constant heat flux boundary condition equal to 100,000,000 W/m2 and can transfer this heat to water flow through the pipe. The water flow reaches the temperature above saturation by receiving heat from the pipe body and is in a superheated state.
As a result, when the water temperature reaches saturation temperature, the water turns into water vapor. Therefore, in the present simulation, a multiphase model is used; its primary phase is liquid water, and its second phase is water vapor. To define the multiphase model, the Eulerian model is used.
This model is the most complex multiphase model and can solve a set of momentum and energy equations for each phase separately. Since this modeling is supposed to deal with the boiling process, the Eulerian multiphase model should be used, and the boiling model option should be activated.
Also, to define the phase conversion process from liquid to gas, a mass transfer with a saturation temperature of 383.15 K must be specified.
Boiling Conclusion
At the end of the solution process, two-dimensional parameters related to pressure, water vapor velocity, water vapor temperature, water vapor volume fraction, and mass transfer rate from water to vapor (boiling) are obtained.
As the pictures show, water flow under the heat caused by the heat flux applied to the pipe wall increases with temperature. After reaching the defined saturation temperature, it turns into steam, or the so-called boiling process occurs.

I was able to run the simulation, but I’m struggling with visualizing the vapor formation in the post-processing stage. Could you advise on the best way to clearly see the phase change in the nanotube?
MR CFD Support –
To visualize vapor formation and phase changes in the post-processing stage, you can utilize the volume fraction contours in ANSYS Fluent. First, ensure that you select the water vapor as the phase you want to visualize. Then, look at the volume fraction contour plots, as these will indicate where the water turns into vapor along the nanotube. Setting a proper scale for volume fraction values—from 0 for liquid water to 1 for steam—will help you discern the phase change more clearly. Additionally, you can use animations to see the boiling process over time, which can provide a better understanding of the vapor formation dynamics.

Mr. Lorenza Hagenes III –
Are there any special considerations taken into account due to the small scale of the nanotube in this simulation?
MR CFD Support –
The small scale of the nanotube in the simulation indeed requires special considerations. Due to the nano-scale size of the pipe, the tendency of the fluid particles to adhere to the wall is quite high because of the high surface to volume ratio. As such, a precise definition of wall treatment and careful meshing to capture the near-wall phenomena accurately are essential. Furthermore, the simulation considers the effects of buoyancy less impactful due to the scale, focusing instead on surface forces such as surface tension and molecular forces.

Walton Cole –
In this training session, does the simulation account for critical heat flux (CHF) and where might it become significant in the nanotube boiling process?
MR CFD Support –
During this training, critical heat flux isn’t specifically addressed in the given description. CHF refers to the point where a boiling surface transitions to film boiling, resulting in a rapid increase in surface temperature. If included in the simulation, it would likely become significant where the heat flux is strongest and where the water’s phase change occurs.

Can you explain how heat flux influences the boiling process in this simulation, especially given such a high value of heat flux?
MR CFD Support –
In this simulation, the high heat flux applied to the wall of the nanotube directly affects the rate at which the water absorbs heat. It is this absorption that raises the water temperature, allowing it to reach the saturation point where boiling occurs. The applied heat then sustains and progresses the phase change from liquid to vapor inside the nanotube.

Reyna Upton –
The simulation explanation is very in-depth and covers things in great detail. It’s fascinating to see how advanced CFD applications like boiling inside a nanotube are being simulated. The results must be quite intriguing. Can you expand on how the phase transition is monitored within the software?
MR CFD Support –
In the software, the phase transition from liquid to vapor is monitored by defining a mass transfer mechanism based on the specified saturation temperature. This is done consistently with the Eulerian multiphase model, which can simulate separate momentum and energy equations for each phase. When liquid water, represented as the primary phase, reaches the saturation temperature (in this case, 383.15 K), the defined mass transfer kicks in to simulate boiling, indicating the formation of water vapor, the secondary phase.
