2020 Fall - CFD LAB 2

• Some of students made a few mistakes and one student express the answer

• Few students calculated wrong friction factor, therefore the relative error could not decrease when the convergence limit is decreasing.. This might happen because students did

• Several students did not plot the residual history graph for both 4deg and 10deg cases.. • Some of student calculated wrong friction force at

• Some of students could not derive the frequency of drag coefficient correctly, so calculate

 Several students used wrong empirical equation to get the fully developed length, so they can’t compare the CFD result correctly for both laminar and turbulent conditions.. 

 Several students answered that 1 st order upwind scheme gives out results closer to the asymptotic range.  Some of student indicated validated

 Several students couldn’t indicate separation point or reattaching point correctly.  Some of student did not answered for all questions in

 Several of students indicated wrong sign for drag coefficient of Ahmed Body(Front Part
