Please forgive me,

I am new to CFD and I am taking an undergraduate course with no prior experience with Fluent or CFD in general. We decided on a project to analyze the coefficient of drag of a smooth sphere in flow as compared to a rough sphere in the same flow to understand the effects of flow separation and pressure drag on the different spheres.

I am wondering if anybody has any references for beginners in navigating the program and understanding the applications of the software (I.e. meshing, boundary conditions, algorithmic schemes, turbulence models).

Any insight is appreciated. I have followed a few tutorials that worked some similar problems, but I am just trying to widen my knowledge base to fully understand the program and what is going on behind the buttons.

Thanks a lot,
Tim

Hi Tim,

Google "Cornell university fluent tutorial" and you'll reach their publicly available FLUENT tutorial page. One of the tutorials is flow past a sphere. Written for version 12 I believe, but also with newer ones, you should figure it out. Includes geometry and meshing.

Good luck!
