Computational analysis of heat and mass transfer flow of wall jet hybrid nanofluid with irregular heat source/sink effects and waste discharge concentration

Abstract

Tailoring hybrid nanofluids to attain a specific and regulated heat transmission is done to fulfill the requirements of various applications, including cooling and cooling systems, as well as the automotive and aerospace sectors, among others. Because of its wide range of applications, the objective of this study is to present a numerically derived solution for a problem based on wall jet flow over a stretching surface. In this investigation, the authors have examined a non-Newtonian Eyring-Powell hybrid nanofluid consisting of water and nanoparticles of CoFe2O4 and TiO2. Additionally, the novelty of the paper is to investigate the influence of a magnetic field as well as the presence of an irregular heat sink/source and the waste discharge concentration. The numerical solution is obtained through the use of a similarity transformation technique and the “bvp4c solver implemented in MATLAB”. The higher values of external pollutant source variation parameter and local pollutant external source parameter causes MT rate to decrease. The temperature of the fluid increases significantly, as the heat source parameters become more dominant. The findings from this study hold relevance for a wide array of fields that make use of wall jet (WJ) applications. These fields include car defrosters, sluice gate flows, drying processes for vehicle or building spray paint applications, cooling systems for high-performance laptop CPUs, and cooling jets applied to turbo-machinery components, among others.
