1.PurposeThe Purpose of CFD Lab 2 is to simulate turbulent airfoil flows following “CFD process” by an interactive step-by-step approach and to conduct verifications. Students will have “hands-on” experiences using ANSYS to conducting verification for lift coefficient and pressure coefficient distributions, and validation for pressure coefficient distribution, including effect of numerical scheme. Students will manually generate C type mesh and investigate the effect of domain size and effect of angle of attack on simulation results. Students will analyze the differences between CFD and EFD, analyze possible sources of errors, and present results in a CFD Lab report.
