Computational modelling of terrain and building aerodynamics for enhancing architectural designs

An attempt at using computational fluid dynamics (CFD) to assess and enhance the architectural design for the proposed new IIT Gandhinagar Campus buildings with flow models integrated with climatic data and wind patterns corresponding to average annual weather conditions in the neighborhood to assess the resulting terrain and building aerodynamic flow patterns and thermal fields is addressedin this work. Computed temperature fields, pressure fields, wakes, vorticity structures for a specific free stream field acquired via multiple meteorological resources applied as Atmospheric Boundary Layer are shown along with the assessment of variation of humidity and its effects on the flow fields and temperature field to show the implications for enhancing architectural designs andserving as a basis for the assessment of natural cooling systems in indoor ventilation.
