Abstract

Highlights: Bingham nanofluid is considered in an inclined non uniform channel with chemically reactive species. Effect of homogenious–heterogenious is depicted in the flow of Bingham nanofluid. Walls are assumed to be flexible. Convective boundary conditions for temperature and concentration equations are considered. Abstract: Objective :The flow kinetics generated with a pulsatile wave that travel along the channel has prime relevance in various processes in physiology and industry. The aim here is to investigate such phenomenon with Bingham fluid with chemically reacting species in terms of their homogeneous and heterogeneous characteristics. Method: To formulate the mathematical descriptions Bingham fluid with heat and mass equations is accounted. Using the similarity solutions, the proposed leading partial differential equations of the flow phenomena transferred into the nonlinear ordinary differential equations and boundary conditions are solved analytically. Such considerations perceive prime importance in medicine and genetics where heterogeneity in a cell makes several diseases difficult to execute. Results : Further the physical aspect of human tabular organs i.e., porosity in a medium is retained in the analysis. The utility of magnetic field in reference to medicine is employed. The walls are considered flexible. The whole problem is set to lubrication approach for simplification of resulting system. The attained results are tested on physical grounds by plotting graphs. Conclusion: It is analyzed that the Hartman number and porosity parameter reduce the velocity and temperature profiles. The elastic wall parameters E 1 and E 2 enhances both the velocity and temperature fields while E 3 enrolls an adverse effect.
