Transient laminar opposing mixed convection in a differentially and asymmetrically heated vertical channel of finite length
Transient laminar mixed convection in an asymmetrically and differentially heated vertical channel of finite length subject to an opposing buoyancy is investigated by solving the unsteady two-dimensional Navier–Stokes and energy equations. Results illustrate the effects of buoyancy strength or Richardson number Ri 1⁄4 Gr=Re and Reynolds number Re on the overall flow structure and the nondimensi...
متن کاملMHD Mixed Convection in a Vertical Porous Channel
Abstract—This work deals with the problem of MHD mixed convection in a completely porous and differentially heated vertical channel. The model of Darcy-Brinkman-Forchheimer with the Boussinesq approximation is adopted and the governing equations are solved by the finite volume method. The effects of magnetic field and buoyancy force intensities are given by the Hartmann and Richardson numbers r...
متن کاملNumerical Solution of Natural Convection in a Vertical Channel.
Natural convection between vertical parallel plates occurs frequently in applications such as solar collectors and cooling of electronic instruments. The problem is a two dimensional developing buoyant flow. In this work, the two dimensional conservation equations are solved numerically for constant wall temperature and constant wall heat flux. The results for the local Nusselt number at the du...

متن کاملTransient Natural Convection in a Rectangular Cavity Filled with Porous Medium Heated Discretely at Vertical Wall
Numerical analysis is presented for transient buoyancy-induced natural convection from discrete heating inside a two-dimensional rectangular enclosure filled with porous medium. The study has been made for Rayleigh numbers of 100, 1000 and 10000 with an aspect ratio of 2. The left vertical wall is heated discretely to a constant high temperature and the right wall is cooled to a constant low te...
