Modified Homogeneous and Heterogeneous Chemical Reaction and Flow Performance of Maxwell Nanofluid with Cattaneo-Christov Heat Flux Law

An MHD boundary layer flow of upper-convected Maxwell (UCM) nanofluid over an extending surface has been studied in the current literature. The most recent double diffusive heat flux model proposed by Cattaneo and modified by Christov has been incorporated into the energy equation instead of the conventional Fourier model in the governing equation of the flow. Homogeneous and heterogeneous chemical reaction is incorporated in the fluid system with heat generation due to the homogeneous chemical reaction and chemical reaction dependent thermal intake capacity of nanoparticles. After an arduous numerical calculation, the impact of numerous germane factors on the heat and mass relocation characteristics of flow has been illustrated through charts and graphs, and the consequences have been explained with proper reasoning. In every graph and table, we compare the outcomes for the conventional Fourier law and the Cattaneo-Christov law. To measure the relation of the flow regulator factor with the flow performance, we introduce correlation coefficients and coefficients of determination and present them with proper charts. It is observed that the correlation is high.

Automated summary
