| 内容記述 | The wind catchers are traditionally used in Middle East and North Africa countries, such as buildings in central of lran and Egypt. It is increasing of ventilations rate for moving fresh air into buildings by natural ventilation, which is friendly, sustainable and environmental energy system. This paper studied behavior of air flow through several one-sided wind catchers with a numerical method by CFD program in order to explore the influences of the wind catcher's roof geometry structure and wind velocity on the ventilation capacity. To achieve this aim, the structure models of one-sided wind catchers with flat roof model for used and the numerical investigations were conducted for various wind velocity in the range of 0.5 to 10 m/s, which operated by the average of wind velocity at Bangkok and others area of Thailand as 0.5 to 5.0 m/s and 10 m range of height. In this study will be learning with ventilation rate of air flow (Q) and pressure coefficients (Cp), which are a factor of efficiency for natural ventilation of building. For the wind catcher with CFD models were measured at several of channels deep such as 20, 40, 60 and 80 mm and 105, 125, 145, 165, 185 and 205 mm for channels height. Therefore, the result of this research had been high discharge coefficient and efficiency of natural ventilation, which this research found that the flat roof models are created ventilation rate for suitable and respond with wind velocity of Bangkok at 0.5 to 5.0 m/s with the flat roof models at 165 mm, 205 mm and 185 mm height respectively for 20 mm channels deep. | |||||
