Abstract
Complex cavity permeated with permeable media was influenced by magnetic field in current modeling. The flow encounters resistance in existence of Lorentz force and to improve thermal features, water was equipped with nano powders. Induce magnetic was ignored and to harness the permeability effect, non-Darcy approach was used. Current model acquired large attention in industry. For examine the correctness of code, the results of 0 was compared with previous basic article and achieved graph illustrates nice conformity of current modeling. Two straight wall were adiabatic, lower and upper walls were confined to hot and cold temperature bath. Laminar flow was established and maximum of Ra is 10(5) and carrier fluid is incompressible. To incorporate the gravity force, Boussinesq principle was utilized. The bottom surface was subjected to hot source and gravity enforces the nanomaterial to go up and create rotating cell. The complex shape of isotherms pertains to stronger convection which is attributed to greater permeability. Involve of MHD, declines the distortion of isotherms and conduction becomes stronger in greater Ha. Rise of Ha leads to decrease in Psi about 60% when Da = 100. Psi augments about 100% with augment of Da when Ha = 0. Rise of Ha provides reduction in Nu about 11.48% and 9.37% when Da = 100 and 0.01, respectively. Rise of Rd offers 106.6% augmentation in Nu when Ha = 0. When Ha = 20 and Da = 100, rise of Ra leads to 99% augmentation in Nu. (C) 2021 Elsevier B.V. All rights reserved.
