Study on Wind Induced Interference Effect of T Shaped Light Camping Housing Group

Abstract

In order to study the wind induced interference effect of T shaped flat light camping house under regular arrangement, based on the theory of atmospheric boundary layer and the basic principle of computational fluid dynamics, the FLUENT software was used to keep the transverse distance Sx=2H unchanged by using the wind direction angle and the longitudinal distance as variable parameters. A total of 15 numerical values are simulated and the T shape is flat under the regular arrangement. The surface wind pressure distribution of the light camping house group is studied. The average wind pressure coefficient of the selected target house is compared with the single house data, and the interference factor is introduced to describe the interference effect of the group housing, and the area and the conditions of the target housing enlarging effect and shielding effect are obtained. The study shows that 0 degrees is the most unfavorable wind angle, and the most interference factor is 3.45, and the interference factor less influenced by the longitudinal distance, and most of the areas are sheltered effect. It can be seen that the wind induced interference effect of the camping house under the regular arrangement should not be ignored, and enough attention should be paid to the design.
