HALL AND HEAT SOURCE EFFECTS OF FLOW STATE ON A VERTICALLY ACCELERATING PLATE IN AN ISOTHERMAL ENVIRONMENT, INCLUDING CHEMICAL REACTIONS, ROTATION, RADIATION, AND THE DUFOUR EFFECT

We examine the collective impact of Hall current and radiation-enhanced thermal sources on the laminar flow of a first-order fluid. The fluid under investigation is incompressible, and the analysis pertains to the heat transfer and accumulation dynamics when this fluid flows over a uniformly heated vertical plate, which is in motion at an elevated speed with rotational motion and the inclusion of the Dufour (Df) effect. We applied the Laplace method to derive  solutions for the pertinent mathematical expressions. Subsequent to the investigation, measurable data was obtained by analyzing the accelerated flow, taking into account specific parameters such as Prandtl, Schmidt, thermal, and accumulation Grashof values. According to the findings, speed rises with higher values of heat source, Hall current and Grashof parameters, but drops as radiation levels rise. Temperature similarly rises with a higher heat source and drops with increased radiation levels. Furthermore, with a rise in the chemical reaction rate, the concentration drops.
