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...

A 2D numerical simulation of the drainage process in a stratified vertical porous channel is performed for different gas flow rates. The porous matrix consists of two cylindrical homogeneous layers of packed sand with different permeability, initially saturated with a wetting phase. The porosity and the permeability of each layer are assumed to be constant. Since the injected gas is provided th...

what we mean by alliteration of homogeneous words is that such alliteration is based on two or more lexical basis that is conspicuously coordinative and homogeneous with each other. they are homogeneous in that their form, structure, and tone, are similar. we can name two homogeneous words, two bases of homonym. it is evident that such words, though homogeneous from one hand, should necessarily...

Flow chemistry studies can sometimes be difficult to reproduce. In this article we provide guidance scientists for experimental details that should considered as part of any organic chemistry-based continuous flow study. A focus is placed on information provided within reported enable experiments more easily and reliably reproduced. Topics covered include reactor components assembly, important ...
