Thermophoretic particle deposition in a mixed convective bioconvection nanofluid with thermal radiation and chemical reaction over an exponential stretching sheet

Thermophoretic particle deposition in a mixed convective bioconvection nanofluid across an exponential stretching sheet embedding within a porous matrix is presented in this article. The analysis accounts for the thermal radiation and chemical reactions that are useful in various engineering and biological applications. The bioconvection for the movement of motile microorganisms significantly enriches heat and solutal transport phenomena. The proposed dimensional governing equations are re-framed to non-dimensional form by utilizing similarity rules which involve diversified factors. The nonlinear coupled transformed set of equations is handled numerically for the employment of the "spectral quasilinearization method" (SQLM) ensuring high accuracy and computational efficiency. The physical behaviour of the pertinent factors involved in the phenomena are discussed and presented in the discussion section. The results are compared with the existing literature showing good agreement and also provide the convergence of proposed methodology. The study reveals a promising application in biotechnological processes i.e., targeted drug delivery, environmental systems involving permeability i.e. groundwater remediation and filtration processes, industrial processes like polymer extrusion, etc. where the control of particle deposition are required.
