UDF’s in Fluent

@midoelgamal

I am interested in working on this task and I can develop the required UDFs for both the non-uniform wall heating and the pulsating inlet mass flow. Before proceeding, I would like to clarify a few technical details to ensure the UDFs are implemented correctly and according to your expectations: Solver details Is the simulation transient or steady-state? (I assume transient due to pulsating flow, but please confirm.) Which solver is being used (pressure-based or density-based)? Inlet boundary condition Is the inlet defined as a mass flow inlet or a velocity inlet? Do you have a specific mathematical expression for the pulsating mass flow, or should I assume a sinusoidal variation? Please confirm the mean value, amplitude, and frequency (or time period) of the pulsation. Wall heating condition Should the non-uniform heating be defined as: Wall temperature, or Wall heat flux? Is the variation: Spatial (along pipe length or circumference), Temporal (time-dependent), Or both? Do you have a prescribed equation for this variation, or should I propose a suitable profile? Units and geometry What unit system is used in the case file? Is the pipe 2D axisymmetric or 3D? Once these points are clarified, I can proceed with writing the UDFs, compiling them in Fluent, and ensuring they are correctly applied to the inlet and wall boundaries.

We can use ufd, to give both the wall temperature and the entering mass flow a variable values, i am a phd in fluid mechanics, and fluent is my specialty, please feel free to contact me for more details.
