abstract: this work presents a numerical study to investigate the heat transfer characteristics of a 2-d rectangular composite porous radiant burner (cprb). in the construction of porous burner, the porous layer is considered to be composite consisting of upstream and downstream layers with equal thickness but with different physical and radiative properties. in the present work, a two dimensio...

Latent heat storage in a shell-tube is promising method to store excessive solar for later use. The unit filled with phase change material PCM combined high porosity anisotropic copper metal foam (FM) of thermal conductivity. PCM-MF composite was modeled as an porous medium. Then, two-heat equation mathematical model, local non-equilibrium approach LTNE, adopted consider the effects difference ...

The present article discusses the solute transport process in steady laminar blood flow through a non-Darcy porous medium, as model for drug movement vessels containing deposits. Darcy–Brinkman–Forchheimer drag force formulation is adopted to mimic sparsely packed domain, and vessel approximated an impermeable cylindrical conduit. conservation equations are implemented axisymmetric system (R, Z...

In situ growth of bacteria in a porous medium can alter the permeability of that media. This article reveals that the rate of permeability alteration can be controlled by the inoculation strategy, nutrient concentrations, and injection rates. Based on experimental observations a phenomenological model has been developed to describe the inoculation of the porous medium, the in situ growth of bac...

In part I, we considered the application of method fundamental solutions (MFS) for solving numerically Brinkman fluid flow in unbounded porous medium outside obstacles known or unknown shapes. this companion paper consider corresponding interior problem a bounded which contains an rigid inclusion $$D \subset \Omega $$ . The D is to be identified by pair Cauchy data represented velocity and trac...

We present a numerical study of convection in horizontal layer comprising fluid-saturated porous bed overlain by an unconfined fluid layer. Convection is driven vertical, destabilising temperature difference applied across the whole system, as canonical Rayleigh-B\'enard problem. Numerical simulations are carried out using single-domain formulation two-layer problem based on Darcy-Brinkman equa...

in this paper, least square method (lsm) and differential transformation method (dtm) are used to solve the problem of laminar nanofluid flow in a semi-porous channel in the presence of transverse magnetic field. due to existence some shortcomings in each method, a novel and efficient method named ls-dtm is introduced which omitted those defects and has an excellent agreement with numerical sol...

Energy generation is currently a serious concern in the progress of human civilization. In this regard, solar energy is considered as a significant source of renewable energy. The purpose of the study is to establish a thermal energy model in the presence of spherical Au-metallic nanoparticles. It is numerical work which studies unsteady magnetohydrodynamic (MHD) nanofluid flow through porous d...
