FLOWLAB SOLUTION 9.121 Use the cylinder template in FlowLab to investigate how the viscous and inviscid surface pressure coefficient distributions, C p = p /( ρU 2 /2), differ for flow past a circular cylinder. For the viscous case, choose a Reynolds number between Re = 10 and 40 (so the steady solver can be used) by selecting appropriate values for the cylinder radius, free stream velocity, density, and viscosity. Use the same values, other than viscosity, for the inviscid case. For each case, plot the pressure coefficient distribution as a function of location on the surface of the cylinder and explain the differences in the two results. Problem Setup The default cylinder radius was used for this problem: Given the Reynolds number range, the Laminar condition was selected for the viscous simulation. For Re < 40, it is advised to use the steady flow solver, as shown below. For this simulation, the Boundary Condition and Materials were altered to give Re = 20.
