Influence of shape factor on a hybrid nanofluid flow over a permeable flat plate with non-Fourier heat flux model: an analysis of entropy generation

Abstract

The current study explores the complex dynamics of hybrid nanofluid flow on a flat plate, examining the effects of various physical parameters such as velocity slip, shape factor, thermal radiation, Cattaneo-Christov heat flux, and chemical reaction. The equations that regulate the system are turned into a set of ordinary differential equations using similarity transforms. The bvp4c technique in MATLAB is then used to solve the equations efficiently. The three cases involving the shape factor—platelet, cylinder, and spherical—are addressed with the results. The rate of increase of the friction factor is 0.02383 for the platelet shape, 0.023825 for the cylinder shape, and 0.023809 for the spherical shape when the volume fraction of multiwalled carbon nanotubes ranges from 0 to 0.105. Research indicates that when the Eckert number varies from 0 to 0.6, the heat transmission rate decreases by 0.4444371 for platelet form, 0.444998 for cylindrical form, and 0.444502 for spherical form. Augmenting the chemical reaction parameter leads to an elevated mass transfer rate. When the values of the chemical reaction range from 0 to 0.6, the Sherwood number surges at rates of 0.2827136, 0.2827211, and 0.2827408 for platelet, cylinder and spherical forms respectively.
