# #Skin-Friction Measurements with Laser Oil-Flow Interferometer # CASE B'.S0 (off design conditions)* # #* Note: Some of the wall shear stress for case B was #obtained while the tunnel was running in an off design #condition (i.e., the boundary layer was 50% thicker due #to dirty inlet screens) and is denoted as case B'. #This data should be used qualitatively only, and #"should not" be used in conjunction with the Cp data or #the LDV data which was obtained using design conditions. # --------------------------------- # X(mm) X(in) Cfx Cfz -330.2 -13 0.00278 0 -254.0 -10 0.00270 0 -177.8 -7.0 0.00258 0 -152.4 -6.0 0.00235 0 -76.2 -3.0 0.001105 0 7.6 0.3 0.00064 0 152.4 6.0 0.00056 0 304.8 12.0 0.00048 0
