Effect of Windows Sizes on Air Circulation inside Building using CFD Simulation
Journal Title: International Journal of Civil, Structural, Environmental and Infrastructure Engineering Research and Development (IJCSEIERD) - Year 2017, Vol 7, Issue 4
Abstract
Indoor air environment of residential building depends on the circulation of air inside the building and exhaust system. It is necessary to have uniform flow of air inside the building at working plane. Buildings are design with natural ventilation strategy to reduce the energy consumption of building. Natural ventilation depends on inside and outside building parameters like, outside wind speed, obstruction in room, shape of building, inlet and out let windows location size, orientation, bouncy force due to temperature variation in wind. Computational fluid dynamics can be used to study the air flow inside room. CFD Simulation results are validated with experimental data and found to be nearby. In present study, effect of windows size on air circulation was studied. Modeling of room was done in Autodesk Revit software and exported to CFD software. Different cases are considered for simulation with constant inlet window size and varying outlet window size. At working plane, velocity reading is recorded for every case. Velocity vector diagram is compared to understand the circulation of air inside the room. As per observation it is found that the velocity vectors at observation points are reducing with increase in outlet window size.
