Description
Heat pipe CFD Simulation Using Multiphase VOF Model, Ansys Fluent Training
In this project, a heat pipe using the multiphase VOF model has been simulated, and the simulation results have been investigated using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
The present model is designed in three dimensions using the Design Modeler software. The dimensions of the present geometry include a rectangle 10 cm long and 1.2 cm wide.
This geometry is meshed in Ansys meshing software, and the total number of cells is 18000.
Also, due to the nature of the present problem, the transient solver has been used.
Heat Pipe Methodology
This study simulated the heat pipe problem using Ansys Fluent software. The project was analyzed using the multiphase VOF model and activating the mass transfer of evaporation and condensation.
A hot wall with a temperature of 400 K and a cold surface with a temperature of 300 K was assumed. Solving the problem in a time-dependent manner, the formation of water droplets in the upper part of the geometry and their downward movement were observed due to capillary and gravity.
Also, the Saturation property was entered piecewise linearly. Moreover, the realizable k-epsilon model is used to solve turbulent fluid equations.
Heat Pipe Conclusion
At the end of the solution process, two-dimensional contours related to water and vapor volume fraction, mass transfer rate, and temperature are obtained.
By observing the volume fraction contours of the water at two different times, it is clear that the repetition loop of the evaporation & condensation process has been established. The droplets formed at the top of the tube move downwards due to gravity and wall capillary.
In addition, mass transfer, temperature, and vapor phase densities are included. The density of the vapor changes over time because it follows the ideal gas law. The mass transfer rate tended toward an average value. This indicates a balance between evaporation and condensation inside the heat pipe.

I was fascinated to see how the droplets formed and moved in the simulation. Can you explain how you handled the wall adhesion properties to mimic capillary action inside the heat pipe?
MR CFD Support –
In the simulation, we appropriately adjust the wall adhesion properties to recreate the capillary effects. This involves defining the contact angles on the walls and ensuring that the wall boundary conditions respect physical realities of the heat pipe operation. By setting these properties correctly, the simulation captures the capillary-driven flow that brings the condensed liquid back to the heat source region.

Dayna Kiehn DVM –
I found the explanation of mass transfer rate’s tendency towards an average value quite interesting. Could you clarify if this indicates a stable operational phase for the heat pipe, and how it affects the overall efficiency?
MR CFD Support –
During the CFD simulation of the heat pipe, as the mass transfer rate stabilizes and trends towards an average value, it does suggest that the system has reached a stable operational phase. In this phase, the balance between evaporation and condensation processes implies that the heat transfer is occurring efficiently. The overall efficiency of the heat pipe is indeed enhanced when there’s a consistent cycle of phase change and fluid movement, as this results in an effective transfer of latent heat.
