INVESTIGATION FOR FLOW ENHANCMENT PHENOMENON OF DILATANT FLOW IN A NARROW SLIT

LDV is used to measure the velocity profiles and near wall velocities fora dilatant flow-gel 107 solution flow in a slit. After some modification in the Poiseuille flow formulas has been made for side-wall effect correction, the results of LDV measurements combined with bulk parameters are utilized to analyse the enhancement evidence and quantities of the flow, The feasibility of using LDV to investigate flow enhancement phenomenon in detail is demonstrated
