Analytical investigation of the effects of free stream fluctuations on the flat plate heat transfer
Abstract
The objective of this study is to investigate the effects of free stream turbulence intensity on the heat transfer from a flat surface. An analogy between conduction and convection is used by applying the simplified time...
Evaluation of Turbulence Models in Predicting Turbulence Penetration in Low Reynolds Number Regions
Turbulence schemes have long been developed and examined for their accuracy and stability in variety of environments. While many flows work with disturbed turbulence intensity, models have rarely been tested to explore whether their accuracy...
Evaluation of Eddy Viscosity Models in Predicting Free- Stream Turbulence Penetration
such augmented free-stream turbulence intensity or declines to an erroneous solution. In the present study, the turbulence intensity of an air flow stream, moving parallel to a flat plate is augmented by the means of locating a grid screen at a point at which Rex...
اثر شدت توربولنس جریان آزاد و گرادیان فشار بر شکل گیری لایه گذرا در کانال واگرا
Paulhausen integral techniques together with Johnson, Redford and Jungho correlations are used in predicting transition onset, separation point position and penetration of free stream turbulence into transitional boundary ...
