Biomedical application of energy and momentum transport in microfluidics in the presence of shear-driven flows

Abstract

Transport of the pressure-driven perturbations with a sharp parallel velocity shear is studied in microfluidics. Studies show that when the second derivative of the parallel velocity with respect to the radial coordinate is positive, the linear mode may become unstable and turbulent momentum transport increases. On the other hand, when the second derivative of the parallel velocity is negative, the linear mode is completely stabilized and turbulent momentum transport reduces. Possible implications of this results in biomedical industry will be discussed.
