FLUENT - Steady Flow Past a Cylinder Problem Specification

Problem Specification

The purpose of this tutorial is to illustrate the setup and solution of a steady flow past a circular cylinder. Flow past a circular cylinder is one of the classical problems of fluid mechanics. For this problem, we will be looking at Reynolds number of 20. 

Re = rhoVD/u (need to change)

Knowing D = 2 m, to obtain Re = 20, we can arbitrarily set ρ, v and μ. For our case, let's set ρ = 1 kg/m3 , v = 1 m/s and μ = 0.1 kg/ms.

Knowing the problem specification, setup the mesh in Gambit and solve this problem using FLUENT. 

Preliminary Analysis

We'll create the geometry and mesh in GAMBIT which is the preprocessor for FLUENT, and then read the mesh into FLUENT and solve for the flow solution.
