Description
Surface Wettability Effect on Pool Boiling Curve, Paper Numerical Validation, CFD Simulation by ANSYS Fluent
The present problem simulates the nucleate boiling inside a vertical channel by ANSYS Fluent software. The simulation is based on a reference paper, “A numerical investigation of the effect of surface wettability on the boiling curve,” Its results are compared and validated with the results in the article. Surface Wettability Effect on Pool Boiling Curve is studied and analyzed.
The water inside the channel is assumed to have a saturated temperature of 373K. The channel has a heat plate (bottom wall) with different temperatures (from 375-475K) to account for differences based on the paper.
Inside the channel, the water has a temperature of 100 degrees centigrade, so the boiling process will start when it comes into contact with the hot bottom wall. If it is big enough, the boiling nucleate will occur, and a hot bubble will separate from the heated surface.
The geometry of this model is designed in ANSYS Design Modeler and is meshed in ANSYS meshing. The mesh type used for this geometry is structured. The total element number is 60000.
Pool Boiling Methodology
It should be mentioned that to simulate two phases of air and vapor, the VOF Multiphase model was activated. The present simulation and its results are transient.
Pool Boiling Conclusion
At the end of this simulation, the results of the present work are compared and validated with the results obtained by the article. For this purpose, the diagram in figure 8 shows the changes in transferred heat flux to fluid based on the changes.
The current project is for the state of contact angle equal to 60 degrees.

Assunta Veum –
I’ve just finished going through the pool boiling simulation course that validates numerical results with a published paper–splendid work! Could you tell me if adjusting the contact angle substantially alters how accurately the simulation matches the physical boiling curve from the paper, assuming all other parameters remain constant?
MR CFD Support –
Adjusting the contact angle does indeed have a notable impact on the wettability of the surface and consequently the simulation results. Surface wettability affects the nucleation rate, bubble dynamics, and heat transfer characteristics. Therefore, it’s essential to accurately replicate the contact angle specified in the experimental setup to ensure that the simulation matches the physical boiling curve presented in the reference paper as closely as possible. Variations in the contact angle will result in discrepancies between the numerical and experimental results.

Prof. Willis Powlowski –
I’m impressed with the level of detail and clarity in the simulation of surface wettability on pool boiling. It’s particularly interesting how the simulation investigates the nucleate boiling inside a vertical channel. Could you explain how the changes in wettability of the heat plate surface affect the onset of nucleate boiling?
MR CFD Support –
Yes, the wettability of the heat plate surface has a significant impact on nucleate boiling. Higher wettability, or a greater contact angle, can result in a higher surface energy barrier for bubble formation. As a result, this can delay the onset of nucleate boiling. Conversely, a surface with lower wettability can reduce this energy barrier, allowing bubbles to form more easily and at lower surface temperatures. The simulation examines these effects and can predict the behavior of bubbles based on contact angle variations on the heated wall.
Antwon Wiza –

What are the primary variables that were adjusted in the simulation to investigate the effect of surface wettability on pool boiling?
MR CFD Support –
The primary variables adjusted in this simulation to study surface wettability on pool boiling are the temperatures on the heat plate (ranging from 375-475K) and the contact angle of the surface, which has been set to 60 degrees in this case. The contact angle directly affects surface wettability, which is crucial for analyzing the boiling curve.

Prof. Garry Ankunding IV –
The simulation results sound very comprehensive! I’m curious if the model features a roughness element on the heat plate to vary the surface wettability effects or does it solely adjust the contact angle in this simulation to study the changes in the boiling curve?
MR CFD Support –
In this simulation, varying the surface wettability effect on the boiling curve is achieved by altering the contact angle to different conditions as per the reference paper. The model doesn’t incorporate physical roughness elements on the heat plate to account for wettability effects; it instead changes the contact angle to simulate these variations.
Ewell Metz –
The simulation error percentages reported—are they within an acceptable range compared to standard validation practices for such CFD studies?
MR CFD Support –
Yes, typically when comparing CFD simulation results to experimental or ‘paper results’, an error in the range of 5-10% is deemed acceptable. Hence, the reported error percentages – 6.429% on average and 4.189% at maximum – fall within this range and indicate a good match between the simulation and the reference paper’s reported results.
Mary Satterfield –
I was impressed with the clear presentation of the surface wettability effects on pool boiling utilizing the validation approach.

I found the simulation very enlightening when it comes to understanding the influence of surface wettability on boiling efficiency. However, could you please explain a bit more about why there is an error percentage between the paper’s results and the present simulation?
MR CFD Support –
The slight error percentage between the paper’s results and the present simulation is likely due to differences in the discretization and numerical schemes used during the CFD process. Additionally, any approximations or assumptions made in both studies could affect the results. Experimental uncertainty in the paper’s data might also translate to differences when compared to the numerically generated data.
Prof. Reymundo Pollich –

MR CFD Support –
The reported error percentages—6.429% average and 4.189% maximum—are within generally acceptable limits for CFD simulations, especially when validating complex physical phenomena like pool boiling. Minor discrepancies can arise from modeling assumptions, simplifications, and computational limitations. It’s excellent that the simulation aligns well with the reference study, illustrating the robustness of the CFD model and the validation process used.
