Numerical analysis of heat transfer in porous inner tube under pulsed current

In this article pulsed flow and heat transfer from the inner porous Lvlhyy with using numerical simulation has been investigated. Sticking to the inner porous layer, the current quasi experimental model Brynkmn Frchmayr) Bsty Darcy model (the model is. Effects of Darcy number, porous layer thickness ratio, the effective thermal conductivity, as well as pulse frequency and amplitude are studied. Results indicate that increasing or decreasing the thickness of porous matrix Darcy number, the pressure gradient increases. Moreover, the thickness dependence on Nusselt number is straightforward. for porous materials with high thermal conductivity, Nusselt number basis consistent with high hickness is increased while For materials with low lead, the distribution of Nusselt seen a minimal amount. is seen that the maximum coefficient of thermal distribution Bhazay a critical thickness of porous material is obtained. Effects of pulse amplitude and frequency on heat transfer also placed scrutiny and analysis.
