4302 Assignment 1: Simulation of Laminar Pipe Flow Problem description Simulate a three-dimensional circular pipe flow using ANSYS Workbench and CFX. The simulation properties are: Pipe inner diameter, D: 12 mm Pipe axial length, L: 0.5 m Default mesh spacing: 2 mm Working fluid: Air at 25C and 1 atm Heat transfer: None Turbulence model: None Inlet boundary: Uniform axial velocity of U0 = 0.4 m/s Wall boundaries: No slip Outlet boundary: Zero gauge static pressure (area-averaged
