Analytical and numerical investigation of heat and mass transfer effects on magnetohydrodynamic natural convective flow past a vertical porous plate
The aim of this investigation is to study the effect of hall current on an unsteady natural convective flow of a viscous, incompressible, electrically conducting optically thick radiating fluid past a vertical porous plate in the presence of a uniform transverse magnetic field. The Rosseland diffusion approximation is used to describe the radiative heat flux in the energy equation. Analytical a...
متن کاملModeling of A Single Turn Pulsating Heat Pipe based on Flow Boiling and Condensation Phenomena
Demand for high-performance cooling systems is one of the most challenging and virtual issues in the industry and Pulsating heat pipes are effective solutions for this concern. In the present study, the best predictor correlations of flow boiling and condensation are taken into account to model a single turn pulsating heat pipe mathematically. These considerations, result in derivation of more ...
متن کاملNumerical Investigation on Flow Field and Heat Transfer Phenomena in Multi-Hole Cooling Configurations
A transpiration cooled flat plate configuration is investigated numerically by application of a 3-D conjugate fluid flow and heat transfer solver, CHT-Flow. The geometrical setup and the fluid flow conditions are derived from modern gas turbine combustion chambers. The plate is composed of three layers, a substrate layer (CMSX-4) with a thickness of 2 mm, a bondcoat (MCrAlY) with a thickness 0,...
متن کاملNumerical investigation of heat transfer and laminar Water-Al2O3 nanofluid flow in a rectangular Rib-Microchannel
در تحقیق حاضر در مورد اثرات ارتفاع دندانه در میکروکانال دندانهدار دو بعدی، بر روی پارامترهای انتقال حرارت و دینامیک سیالات محاسباتی جریان آرام نانوسیال آب-اکسید آلومینیم است. بررسیهای این تحقیق به صورت عددی با نرم افزار تجاری فلوئنت3/6 برای اعداد رینولدز10 و 100، برای چهار حالت مختلف ارتفاع دندانه انجام شده است. افزایش ارتفاع دندانههای داخلی یا مغشوشگرهای جریان، عملکرد انتقال حرارت جابجایی د...
متن کاملAn experimental investigation of heat transfer of Fe2O3/Water nanofluid in a double pipe heat exchanger
One way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. In the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. In this work, the performance of water / iron oxide nanofluid in a double...
