A boundary integral approach for determining the pressure error Academic Article uri icon


  • The rectilinear flow of a second-order fluid is considered between two infinitely wide and long parallel plates. The bottom plate is at rest and has a slot of depth 'd' and width 'W' while the top plate is flat and moves along the flow direction with constant speed. A boundary integral equation technique is developed to determine the pressure error due to such a flow. We find that our numerical results compare favorably with the exact solutions obtained by Kearsley for a special case. Also our results lie within the analytical bounds established by Rajagopal and Huilgol for the pressure error for such flows. © 1980 Dr. Dietrich Steinkopff Verlag.
