A permeable squeezed flow analysis of Maxwell fluid near a sensor surface with radiation and chemical reaction

Abstract

The goal of present work is to explore the two dimensional, unsteady and incompressible squeezed Maxwell fluid flows between infinite parallel plates in a permeable medium. Flows in porous channels/tubes are of particular relevance in a variety of biological and mechanical engineering applications. Sensor surfaces are employed to detect germs and help to diagnose diseases in medical. The computational aspects of thermal radiation and heat generation for thermal boundary layer are investigated. In important engineering activities such as drying, temperature regulation, and moisture distribution, chemical reactions affect heat and mass movement. Mass transfer affected by chemical reaction is analyzed. For porous medium, Darcy law is applied and the governing equations are simplified by boundary layer approach. The similarity transformation is applied to transform the governing equations into ODEs which are solved by BVP4C method. The effects of porosity parameter, permeable velocity and Maxwell number on velocity are studied numerically and graphically. The impacts of heat radiation, Prandtl number and heat generation on temperature field are addressed. The influence of Schmidt number and chemical reaction on concentration field is examined. Velocity of the fluid drop for the improvement in porosity parameter, permeable velocity and Maxwell number. Thermal radiation and heat generation increase the temperature whereas mass diffusivity fall by increasing chemical reaction coefficient and the Schmidt number. Effects of Maxwell parameter, heat generation and chemical reaction on physical quantities are studied.
