CONVECTIVE HEAT AND MASS TRANSFER IN THREE-DIMENSIONAL MHD CASSON NANOFLUID FLOW OVER AN EXPONENTIALLY STRETCHING POROUS SHEET WITH THERMAL RADIATION AND CHEMICAL REACTION

This study aims to investigate 3D flow of a nanofluid created by an exponentially expanding sheet in presence of a heat source and a chemical radiation source, using principles of magnetohydrodynamics (MHD). The analysis utilizes Casson fluid model and considers the impact of a porous matrix on the behavior of Casson nanofluid. Additionally, study finds convective conditions on surface and effects of thermophoresis and Brownian motion. Nonlinear PDE governing heat, mass, and flow are transformed into interconnected nonlinear ordinary differential equations using similarity parameters. These equations are then solved using Runge-Kutta fourth-order integration scheme and the shooting method. The study also presents impact of various parameters through graphs and tables. Taking Casson fluids and Newtonian fluids allows for establishment of dual solutions. The acquired results and the outcomes from the past are compared, and the connection between the two sets of results demonstrates that there is a strong correlation between them.
