Research ArticleOpen accessIn the author namesNumerical Study of Airflow around Vehicle A-pillar Region and Windnoise Generation PredictionM. H. Shojaefard, K. Goudarzi, H. FotouhiFlow separation and reattachment around the vehicle A-pillar region dictates strong pressure fluctuations on the side window surfaces and can also lead to generate aerodynamic noise. The objective of this work is to investigate qualitative flow visualization of airflow behaviour around vehicle A-pillar and its potential to generate windnoise in this region. By means of Computational Fluid Dynamic (CFD) under … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,335 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Numerical Estimation of Thermal Contact Resistance in Contacting SurfacesM.H. Shojaefard, K. GoudarziFor some manufacturing processes, the heat transfer between the components, the tools and the environment has an effect on tool-life and the accuracy of the formed component. Consequently, the measurement of Thermal Contact Resistance (TCR) is of increasing interest to researchers and industrial engineers participating in the manufacture of high-precision components. A new transient method and measurement apparatus are used … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,451 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Study of Thermal Contact using Nonlinear System Identification ModelsM.H. Shojaeefard, K. Goudarzi, A.R. Noorpoor, M. FazelpourOne interesting application of system identification method is to identify and control the heat transfer from the exhaust valve to the seat to keep away the valve from being damaged. In this study, two co-axial cylindrical specimens are used as exhaust valve and its seat.

Research ArticleOpen accessIn the author namesNumerical Simulation of 2_D Turbidity Currents and Wall JetM.H. Shojaeefard, K. Goudarzi, H. Ghasvari JahromiDense underflows are continuous currents, which move down the slope due to the fact that, their density are heavier than ambient water. In turbidity currents the density differences arises from suspended solids. Vicinity of the wall make density currents and wall jets similar in some sense but Variation of density cause this flows more complex than wall jets.
