Abstract
Investigation of the entrainment of fluids induced by a wavy deformation along walls in a flat-plane microchannel is conducted by using the relaxed model with velocity-slip boundary conditions. Flow patterns tuned by critical reflux values a/sub 0/ and Reynolds number are demonstrated especially for the free pumping case. Results show that once the cross-section of the microchannel is narrowed down (velocity-slip increases) there will be earlier backward flows.
