Abstract
The paper is aiming to examine the magnetic impacts on the mixed convection of a nanofluid contained by an undulating porous cavity with the help of radiative and heat generation. The condition of the local thermal non-equilibrium (LTNE) is considered. The partial heater is in the corrugated bottom partition and the top corrugated partition has Tc. The vertical walls are adiabatic with a lid-velocity in the right wall. The regulating equations are worked out by the finite volume method (FVM). The involved parameters are the heater length B (between 0.2 and 0.8), heat generation/absorption coefficient Q (between −2 and 2), modified conductivity ratio (between kr=0-10), thermal radiation parameter Rd (between 0 and 5), a porosity parameter ε (between 0.4 and 0.9), heater position D (between 0.3 and 0.7), thermal conductivity ratio kfs (between 4 and 0.25), an undulating number λ (between 1 and 5), Darcy parameter Da (between 10-1 and 10-5), an inclination angle of a cavity α (between 0°and 90°), nanoparticles parameter ϕ (between 0 and 0.1), and coefficient of an inter-phase heat transfer H∗ (between 0 and 5000). The results indicated that the growth in nanoparticles parameter augments the profiles of average Nu of a fluid phase. The heat transfer is influenced by the variations in the length/position of the heater source. The maximum of the streamlines decreases by 97.55% as Da decreases from 10-1 to 10-5 and increases by 42.86% as an undulating number λ raises from 1 to 5.
