Wind flows and pressure on the Joglo roof, one of Indonesia's traditional houses: A simulation and numerical study
Keywords:
Joglo’s Roof, OpenFOAM, ParaView, WindAbstract
Joglo is one of the traditional houses in Indonesia. Joglo roof has a different angle. Angle of the Joglo roof is very important to note. In this study, simulated wind with a speed of 10 m/s hitting the Joglo’s roof, with roof angles 0 o , 35o , 45o , and 55o . The simulation is completed through the Standard k-Epsilon turbulence model with several functions in OpenFOAM and ParaView. First the wind is set in the direction of the x axis and the second is set in all directions towards the horizontal x and y direction, and towards the vertical z direction. The overall flow pattern shows that the velocity gradient towards zero is at the rear of the joglo roof. In unidirectional winds, the highest pressure occurs when the wind bends at a distance of ±45 m. While the lower pressure is on the back of the roof. For wind from all directions, the highest wind speed is at a distance of 7m to 13m. The greater the angle of the Joglo roof, the greater the initial pressure received, and the greater the decrease in pressure value due to the wind being deflected to the vertical z direction.
