Exercises


To study the effect of the Reynolds number, increase Re to 40 by adjusting the viscosity in FLUENT. Obtain the numerical solution for Re=40 on the original mesh.

Compare the streamline distribution and total drag coefficient with results in "A Numerical Study of Steady Viscous Flow Past a Cylinder" (Fonberg, 1980). What is the effect of increasing Re on the separation bubble behind the cylinder and on the drag coefficient?

Exercises

Consider the steady flow past a cylinder at Re=40. All other parameters from the tutorial are the same except the kinematic viscosity. Simulate this flow using FLUENT.

1.

Plot the streamlines near the cylinder.

2.

Calculate the drag coefficient from your FLUENT results and compare with Fonberg's paper, "A numerical study of steady viscous flow past a cylinder" (1980).
