Effects of both variable electrical conductivity and microstructural/multiple slips on MHD flow of micropolar nanofluid

Abstract

Through heating processes, electrical conductivity plays a crucial role in the food industry. The effects of Joule heating and temperature-dependent electrical conductivity on the boundary layer flow of micropolar fluid were the main topics of this paper. Considerations include thermal radiation, activation energy, and microstructural/multiple slips effects. The resulting partial differential equations system (PDEs) is transformed into a nonlinear ordinary differential equations model using the proper similarity variables (ODEs). The shooting technique, a highly reliable/accurate technique, is used to obtain semi-analytical results. In Mathematica13.1.1, apply the generalised differential transform method (GDTM), Dawar 2021 newly published results are used to approve/confirm the accuracy of the acquired results. Findings demonstrate that the parameter of temperature-dependent electrical conductivity enhances fluid temperature and increases energy gain in the heating operation system, which is important for the design of Ohmic heaters (food industry processes).
