I have done a research on car aerodynamics using ANSYS. But the solid model and boundary conditions were unique. How the results should be compared with existing published papers? and also how the CFD study should be validated?
Ho dear ....
You must fix either solid or boundary condition to nearest model that verified then run and validate your work with this case and then do your work.
There is always a technique to validate your results with a considerable level of confidence. In your scenario, it is not clear whether the car has a novel geometry or the boundary conditions chosen to be "unique", since coupling of both unique geometry and physical conditions probably implies rare or unrealistic supposed operation conditions. The wisest approach is to establish your mesh and turbulence model accuracy by running a previously studied solution with as close as possible geometrical and physical parameters, then to run your analysis with some guiding light.
Good luck!
I think you have to choose the model closest to your conditions and started the exicution so that your work can be original and after the validation so easy.
Hello Shamudra,
You will need to test your CFD model with common case studies such as Ahmed body or so. There are trusted experimental data published and you can download the whole case study and start emulating the same boundary and initial conditions to validate your work. I have done some work on that and you can check my published paper below:

Also, you can find the published data in the link below:

I hope this helps.

Hi Shamudra,
I also agree with Hayder Al-Jelawy. You could also study few benchmark cases to gain insight about validation of CFD results. You should try to compare pressure distribution and force and moment coefficients with experimental data. Here is the link to some very good benchmark case studies available on Ingrid Cloud website.
