Verification of Laminar and Validation of Turbulent Pipe Flows 58:160 Intermediate Mechanics of Fluids CFD LAB 1 By Timur Dogan, Michael Conger, Maysam Mousaviraad, Tao Xing and Fred Stern IIHR-Hydroscience & Engineering The University of Iowa C. Maxwell Stanley Hydraulics Laboratory Iowa City, IA 52242-1585 1. Purpose The Purpose of CFD Lab 1 is to simulate steady laminar and turbulent pipe flow following the “CFD Process” by an interactive step-by-step approach. Students will have “hands-on” experiences using ANSYS to compute axial velocity profile, centerline velocity, centerline pressure, and friction factor. Students will conduct verification studies for friction factor and axial velocity profile of laminar pipe flows, including iterative error and grid uncertainties and effect of refinement ratio on verification. Students will validate turbulent pipe flow simulation using EFD data, analyze the differences between laminar and turbulent flows, and present results in CFD Lab report.
