The fluid flow through inclined plates has several applications in magneto-aerodynamics. materials processing and magnetohydrodynamic propulsion thermo-fluid dynamics. Inspired by these applications. the rate of entropy production in a bio-convective flow of a magnetohydrodynamic Williamson nanoliquid over an inclined convectively heated stretchy plate with the influence of thermal ra... https://www.houseandholders.shop/product-category/pestles/
