Unsteady natural-convection MHD flow of the generalized Maxwell fluid past a canted porous plate

Abstract

The natural-convection magnetohydrodynamic (MHD) flow usually takes place in the process of many industries, such as astrophysics and electronics. In this work, the MHD flow characteristic and heat behavior about the generalized Maxwell fluid passing the canted porous plate under the titled magnetic field is investigated, which is stemmed from the effect of the heat absorption, thermal radiation, the first-order chemical reaction and radiation absorption. And for the temperature and concentration, we established the single-phase-lag model to describe the anomalous transported process. By utilizing the Laplace-transform (L-T) and Fourier-sine transform (F-ST), the solutions in the transformed domain about velocity, temperature, concentration are given analytically. Then the semi-analytical solution can be denoted via the inverse F-ST and numerical inverse L-T. Further, the cognate parameters’ impacts on the solution are discussed and the results are displayed intuitively via profiles.

“…Systems involving unsteady free convection oscillation involve fluid motion due to the temperature and density difference between the fluid and its environment and the regular movement of a boundary or an external force. The heat and MHD flow characteristics of a generalized Maxwell fluid over a porous, canted plate under a tilted magnetic field were explored by Li et al 34 Raptis et al 35 examined the asymmetric flow of a fluid that can conduct electricity in a magnetic field over a stationary plate that extends infinitely, considering the effects of radiation. Ali examined how the second law of thermodynamics affected the flow of a nanofluid that can conduct electricity over a rotating disk with pores, considering the influence of a vertical magnetic field applied externally.…”
