Fluid Mechanics Problems for Qualifying Exam
Name: Fluid Mechanics Problems for Qualifying Exam(Fall 2014)1. Consider a steady, incompressible boundary layer with thickness, (x), that de-velops on a flat plate with leading edge atx= 0. Based on a control volume analysisfor the dashed box, answer the following:a) Provide an expression for the mass flux mbased on ,V ,and .b) Provide an expression for the wall shear stress, w,basedon ,V ,uand .c) Consider a linear velocity profile,u(y). Provide an expression for was a functionof ,V andd ) The expression from (c) by definition equals w= u/ yaty= 0. Providean expression for (x)basedonRex= V x/ ) Provide the skin friction coefficient,cf= V2 , ) Based on the boundary layer shape, do you expect the skin friction coefficientfor the Blasius boundary layer to be larger or smaller than your answer from (e)?12. Consider a uniform flow with velocityUin the positivexdirection combinedwith two free vortices of equal strength located along they-axis.
