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