Unformatted text preview: FLOWLAB SOLUTION 8.141 Use the results from Problem 8.140 to examine the flow separation region for the three different expansion ratios, R 2 / R 1 , considered. For one of the expansion ratios, provide a qualitative visualization of the flow separation past the expansion by plotting the streamlines as well as the velocity vectors. Comment on the velocity profiles in the reversed flow region, particularly in the reattachment zone. In addition, compare the flow separation regions for the three expansion ratios. Export the data for the wall shear stress, τ w , in the exit pipe and on one graph plot shear stress as a function of the distance along the exit pipe for all three cases of the radius ratio. Develop a method to quantitatively determine the extent of the flow separation region for each expansion ratio. Also provide reasoning for the trends seen in the wall shear stress data. Problem Setup See Problem 8.140 solution for details....
