Critical assessment of the y+ and different near wall treatments in CFD modelling of turbulent flows involving no-slip wall boundary conditions.
Comparing the results and critical assessment of the performance of k-epsilon and the Reynolds stresses turbulence models for CFD modelling of the atmospheric air flow in the annular space between two pipes with the following geometry and boundary conditions: annular space between two pipes with inner diameter of 120 mm, outer diameter or 140 mm, and pipe length of 10 m; the inlet air mass flowrate of 0.3 kg/s at temperature of 25 C, inner wall is adiabatic, and the outer wall is at a constant temperature of 600 C

how do i go about doing this?

It usually goes a little something like this: apply the knowledge you gained in that course to do the homework for said course.
Seriously, if you have any specific question, I am sure people here are willing to help. But just copy&paste your homework is not how forums work.

Yeah fair enough, I'm familiar with modelling k- epsilon but I don't know how to model the Reynolds stress turbulence in fluent.

Thanks for any help
