Impact of entropy generation and chemical reaction analysis of nanofluid flow over a linear stretched surface

Abstract

We present a model that analyses entropy generation for the nanofluid flow across a stretched surface with chemical reaction. Determining how entropy growth and chemical reaction affects heat transfer characteristics over a stretching sheet is the aim of this study. The mathematical modeling is characterized by conservation laws of mass, linear momentum, energy, and concentration. It is believed that the presence of nanofluids inhibits the effects of thermophoresis and Brownian motion. Similarity variables are utilised to transform the governing PDE into a nonlinear ODE. The shooting method and RKF approaches were used to numerically solve the ODE. Various factors are used to analyse physical characteristics such as skin friction, temperature, velocity, concentration, Sherwood and Nusselt numbers for stretching. In a restricted sense, a comparison study is conducted with the previously reported results.  The main objective while building different thermal devices is to use energy as efficiently as possible. Energy efficiency in thermal engineering operations can be increased by reducing entropy generation.
