Entropy generation analysis of couple stress Casson fluid flow through non-permeable stretching channel

Channel flow is an important component of Earth's hydrological cycle, supporting human societies, ecosystems and the overall functioning of the planet. Its management and conservation is essential for sustaining water resources and maintaining the health of aquatic ecosystems. The current article demonstrates the utilisation of the semi-analytical differential transform method. The Casson fluid, incorporating a couple stress term, was utilised in flow analysis to lessen entropy formation. The convection was modelled linearly alongside heat radiation within the context of Darcy-Forchheimer flow. The governing equation of the flow, along with the energy equation, was reduced into highly nonlinear ordinary differential equations by similarity transformations. Key variables of the current article such as Bejan number, thermal radiation parameters, Forchheimer number, Casson fluid parameter, skin friction coefficient, heat transfer rates and their effects were noticed. Entropy generation number improves with enhanced inputs of porosity medium parameter while it goes to down with Casson fluid parameter. Temperature profiles are demonstrating improving nature with larger data of Forchheimer and Brinkman number.
