CFD simulation for the feasibility study of a modified solar chimney applied for building space heating

摘要

The building integrated Modified Solar Chimney (MSC) have been studied for building space heating. The Computational Fluid Dynamics (CFD) software (ANSYS WORBENCH 14.0) has been used for simulation and results are validated through experimental data, and mesh adoption is used for new chimney design approvals. From the CFD simulation, it is found that the lowest (20 - 35℃) air temperature is at the middle of solar chimney gap and highest near the absorber plate (45 - 65℃). The experimental room can be maintained between 10℃ to 20℃ in peak winter season, where ambient temperature was observed as 3℃ to 8℃. This modified solar chimney works as an air heater and it is a feasible option for space heating of building.
