Abstract. In this work, we are interested on the study of the aerodynamic structure around an obstacle with inclined roof for a Reynolds numbers equal to Re=2666. The software "SolidWorks Flow Simulation" has been used to present the local characteristics. The numerical model considered is based on the resolution of the Navier-Stokes equations in conjunction with the standard k-ε turbulence model.
IntroductionThe charactristics of the flows around building-shaped obstacles are different from those in laminar boundary immersed in turbulent boundary layers. It is important for the appropriate estimation of wind loading to investigate these characterestics of flows observed under oncoming turbulence (Nozawa and Tamura, 2002;Kawai, 1999). Computational simulations have an advantage to clarify the process and mechanism of these localized phenomena. In recent years, several methods to generate turbulent inflow data were proposed and some of them were used as inflow data (Kondo and Murakami,1997; Kataoka, and Mizuno,1999; Noda and Nakayama, 1989). In this context, Nasrollahei et al. (2013) used a builder software to study the thermal and cryogenic performance. The results of the research show that the temperature of Shevaduns in summer is less than the average maximum temperature and the average minimum temperature of outdoor, and the thermal condition of the Shevadun space during the measurement is lower than the thermal comfort limit which is specified in the standard.
