STUDY OF EFFECT OF WINDOWS LOCATION ON VENTILATION BY CFD SIMULATION

For sustainable design of building ventilation plays very important role. With proper location of inlet and outlet windows, uniform flow is possible at working area. Tunnel study was performed by researchers to understand the flow patterns. Since civil engineering structures are of very big scale, there is limitation on tunnel study of civil engineering structures. With availability of advance computing hardware and software, it is possible to model the air flow on desktop computer. Computational Fluid Dynamics (CFD) has open new doors for researchers to simulate practical problems on computers. Researchers and software developing company has validated the software with experimental results. Paper present the air flow pattern inside the room. Autodesk CFD2016 Simulation tool was used for simulation. Twelve Simulation cases with different inlet and outlet window location were defined. For every case, air velocity was measured inside room at working plane. Cumulative air velocity at observation points are compared between different cases. Simulation case which give maximum circulation of air on working plane was selected as best alternative. As per simulation result it is found that, if windows are placed at crossing, then maximum air circulation can be achieved. Air flow found to be maximum when inlet and outlet windows are placed on opposite walls. Vector diagrams of air circulation for different cases are helpful to understand the air flow inside the room.
