Exercise 1

Laminar Pipe Flow

Consider developing flow in a pipe of length L = 8 m, diameter D = 0.2 m, ρ = 1 kg/m3 , µ =2 × 10−3 kg/m s, and entrance velocity uin = 1 m/s (the conditions from the FLUENT case considered in class). Use FLUENT with the "second-order upwind" scheme for momentum to solve for the flowfield on meshes of 100 × 5, 100 × 10 and 100 × 20 (axial points × radial points). The mesh files can be downloaded from Blackboard.
