Optimization of dissipative-magneto highly reactive Casson nanoliquid flow with an electric field utilizing response surface methodology

Abstract

ABSTRACT The studies of a first-order chemical reaction have been presented in various published investigations, while the nth chemical reaction should be examined. Also, optimizing the effect of process variables is important for a clear understanding of the heat transfer mechanism. Therefore, this paper presents an optimization and sensitivity analysis for the heat transfer and shear rate utilizing response surface methodology (RSM) for dissipative-magneto highly reactive Casson nanoliquid flow with an electric field. The irreversibility property is disclosed, and both active and passively controlled cases are assumed. The governing system is transformed into similar forms and solved using the Blottner technique together with the Finite Difference Method (FDM). The main attraction of the current investigation is to optimize the rate of heat transfer as well as the shear rate by utilizing robust statistical approaches. Further, sensitivity analysis for the significant factors is, also, demonstrated for the proposed responses. The major outcomes revealed that the skin fraction is enhanced as the magnetic parameter is altered, while the electrical coefficient causes a reduction in the velocity gradients. In the active-controlled case, the power index of the chemical reaction reduces the mass transfer rate.
