The current study presents a novel examination of heat transfer properties in a magnetohydrodynamic (MHD) flow of Casson fluid across a porous stretching sheet. uniquely incorporating the effects of heat source and variable viscosity. Unlike previous studies. this research employs the Lie similarity transformation to convert the governing equations into a dimensionless form. https://www.roneverhart.com/Sheepshead-Bay-Boats-2-Brooklyn-NY/
