CFD Analysis of Air and Steam in a Rectangular Channel Having Parallel RIBS
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 11
Abstract
A Computational fluid dynamics analysis of air and steam cooling a rectangular channel with parallel ribs. The effects of Reynolds numbers (Re), rib spacing ratio (P/e), and rib angles (α) on steam and air convective heat transfer were obtained. Heat transfer distribution is done for rib spacing ratio (P/e)=8, 10 and 12 and ribs angle 900 to 450.The heat transfer enhancement of both air and steam increased with decreasing the rib angle from 90° to 45° . Although both air and steam flow are similar to each other, the steam flow obtains a high convective heat transfer enhancement capability. For the corresponding degrees the heat transfer coefficient decreases and a study is made on rectangular duct having acute and right angled ribs based on a backflow. Study is made on P/e = 8 having higher strength when compared with P/e = 12 is analyzed based on heat transfer of air and steam flow through a rectangular duct. The modelling has be done on the Creo parametric 2.0 software and to get the exact mesh of the duct the meshing was done in Hypermesh and the analysis were done in CFD Fluent software.
