Entropy generation analysis of hyperbolic tangent fluid in upright microchannel with Hall effect by Taylor wavelet collocation method

Abstract
This study investigates the behaviour of a tangent-hyperbolic fluid as it moves through a vertical microchannel, taking into account convective boundary conditions, a transverse magnetic field, and the Hall effect. The study begins with the derivation of the fundamental dimensional equations, which are subsequently transformed into a dimensionless format through suitable transformations. For the first time, the novel Taylor wavelet method is applied to semi-analytically address these transformed flow equations. Graphical representations are employed to illustrate the influence of various parameters on temperature, velocity, and entropy generation within the flow system. The findings indicate that an increase in the Hall parameter promotes flow development in both primary and secondary directions. Furthermore, a rise in the Weissenberg number impacts temperature in a manner that contrasts with the effects of an increase in the power-law index.
