Abstract

Highlights: Mass transport of neutral solute across porous wall of a microtube is derived. Combined effects of electroosmosis and pressure on flow system are observed. Casson rheology is used, which is most realistic model to represent blood flow. Disease detection is proposed based on location of stationary point. Abstract: Mass transport characteristics of a neutral solute in a Casson fluid through a microtube with porous wall under the influence of both pressure and electric field are attempted in this work. The velocity and concentration fields were derived from first principles analytically. The expression of Sherwood number was obtained and impact of rheological parameters on Sherwood number was quantified. Influence of system parameters on solute transport characteristics in terms of permeation flux and concentration was established in detail. Finally, a theoretical method was developed to identify the diseased state by detecting the stagnation point in the microfluidic platform without any chemical reagents.
