Abstract
The study of effects of wind flow surrounding the low-rise house with mono-pitch roof considering overhang become the focus of the present study. Many windstorms event occur past few months and cause several damaged to the roof especially in low-rise house. However, the previous studies are limited to the low-rise house with gable roof. The numerical study using Computational Fluid Dynamic (CFD) simulation was performed to simulate the wind flow toward house, resulting a pressure distribution surrounding the house. Therefore, the study is conducted to investigate the effect of house features namely overhang and roof pitch on the wind flow surrounding the low-rise house using CFD. The steady-RANS equation using RNG k-ε turbulence models were introduced to solve the flow problems for this study.The highest-pressure coefficient was recorded to be 0.97 for model MR 5. Meanwhile the model with 18˚ roof pitch developed the highest suction effect occurred on the roof overhang with the values of net Cp calculated to be -2.6933. Finally, the results using overhang roof and roof pitch of 18˚ cause the most significant influences to the Cp values.
