For the heat and mass transmission processes, the consequences of radiative heat flux, chemical reaction and thermophoretic particle deposition are applied and analyzed. The proposed model has been supported by the prescribed heat and mass flux conditions. By applying the proper mathematical transformations, the set of non-linear partial differential equations is converted into a system of ordinary differential equations that are nonlinear. The bvp4c package is utilized and influence of squeezed flow parameter on temperature, velocity, and concentration fields is examined graphically. The consequences of Deborah number, Jeffrey model parameter i.e., relaxation to retardation ratio, and magnetic parameter on velocity field are discussed and presented graphically. Furthermore, the impacts of heat generation/absorption coefficient and radiation parameter on temperature field and impacts of thermophoretic parameter and chemical reaction parameter are discussed on temperature and concentration distributions respectively are presented through graphs. Wall drag coefficient, heat transmission and mass transfer rates are described mathematically, and their numerical values against different estimations of emerging physical parameters are demonstrated in tabular form. Comparison of present work is also added.

The mass analyses and heat transfer are executed while considering chemical reaction of second order and thermal radiation respectively. The nanofluid stability is enhanced by the presence of the bioconvective effect. Using appropriate similarity transformations, the modeled governing equations for thermal, momentum, concentration, and bioconvection are reduced to ordinary differential equations. The bvp4c program is employed to resolve these reduced equations. The corollaries are outlined in the mode of illustrations and numerically calculated values furnished in the form of tables. Further, Nusselt, Sherwood, Motile microorganisms numbers and skin frictions are calculated and tabulated. The authenticity of the model is also a part of this investigation.

Instead of considering constant thermal conductivity, viscosity, and diffusivity, their variable forms are engaged to portray a more realistic phenomenon. The Cattaneo-Christov heat flux theory with convective mass and heat conditions is used to evaluate the heat transfer analysis. The influence of thermophoresis and Brownian motion on the stability of nanoparticles is further examined using Buongiorno’s model. To derive the system of differential equations from the set of partial differential equations involving the boundary layer notion, similarity transformations are engaged. The MATLAB software bvp4c package is employed to acquire the numerical solution to the visualized model. The visual portrayal of the parameters that affect dimensionless temperature, velocity, and concentration is added. The Skin friction is shown in table format for a range of parameters. The validation for the truthfulness of the model will also be added. Supervised by Dr. Muhammad Ramzan Mon, 01 Jan 2024 00:00:00 GMT http://hdl.handle.net/123456789/19156 2024-01-01T00:00:00Z
