Investigation of buoyancy-driven flow and heat transfer in a trapezoidal cavity filled with water–Cu nanofluid

Heatline visualization of natural convection in a trapezoidal cavity partly filled with nanofluid porous layer and partly with non-Newtonian fluid layer

“…(22)- (29) subject to the boundary conditions (30)-(33) which are solved numerically based on the Finite Volume Method (FVM) using a collocated grid system.…”

“…Obviously, matching of the stresses at the interface can only be accomplished if Brinkman's extension is used in the momentum equations for the porous layer [4]. In the interface, x and y are the Cartesian coordinates measured in the horizontal and vertical directions respectively, K represents the permeability of the porous medium and g is the acceleration due to gravity, / stands for the solid volume fraction of nanoparticles, a nf is the effective thermal diffusivity of the nanofluids, q nf represents the effective density of the nanofluids and ðqCpÞ nf is the heat capacitance of the nanofluids, defined in [29] as…”

Transient natural convective heat transfer in a trapezoidal cavity filled with non-Newtonian nanofluid with sinusoidal boundary conditions on both sidewalls

“…Nasrin and Parvin [24] used the finite element method to study buoyancy-driven flow and heat transfer in a trapezoidal cavity filled with a water-Cu nanofluid. Noghrehabadi et al [25,26] studied numerically the effect of a partial slip boundary condition on the flow and heat transfer of nanofluids past the stretching sheet using the Runge-Kutta-Fehlberg method.…”

Analysis of Natural Convection Flow in a Trapezoidal Cavity Containing a Rectangular Heated Body in Presence of External Oriented Magnetic Field

“…Hasanuzzaman et al [7] studied a computational numerical work to see the effects of magnetic field on natural convection for a trapezoidal cavity. Nasrin and Parvin [8] conducted a numerical research in order to investigate the transport mechanism of natural convection in a trapezoidal cavity filled with Cu-water nanofluid. They found that both aspect ratio and Prandtl number affect the fluid flow and heat transfer in the cavity.…”
