Peristaltic flow of a bioconvective sutterby nanofluid in a flexible microchannel with compliant walls: Application to hemodynamic instability

Abstract

A theoretical investigation is conducted for bioconvective peristaltic transport of a non-Newtonian nanofluid through a porous symmetric channel with compliant walls. The Sutterby nanofluid model is utilized to characterize the fluid under an applied magnetic field. The use of radiative heat flux along with the heat source and the thermodynamics energizes the flow phenomena. In addition, the novelty of the present study is to analyze the behavior of bioconvective Sutterby nanofluid in a chemically reactive porous channel with heat and mass transfer aspects. To reduce the complexity of the system, we used a long wavelength and low Reynolds number approximation. Furthermore, to tackle the dimensionless equations related to the flow phenomena, numerical computations are performed by utilizing MATLAB's built-in bvp5c function. The consequences of the pertinent parameters on the flow characteristics are presented through tables and graphs. An increase in both the Darcy number and the buoyancy ratio parameters raises the velocity distribution of a Sutterby nanofluid. The magnitude of the thermal field is enhanced in a symmetric channel with a rising Eckert number and the energy generation parameter. The thermophoresis diffusion parameter strengthens the temperature profile but decreases the concentration of the Sutterby nanofluid. We believe that the outcomes of this study have a wide range of implications to targeted drug delivery, the pharmaceutical industry, thermal devices, biosensors, sustainable fuel cell technologies, and solar systems.
