Analysis of wind-induced internal pressure in enclosures

A mathematical approach is developed for the dynamics of wind-induced pressures within enclosures. The model is based on the equations of mass conservation and motion, and the state equation of gases. It takes into account the characteristics of leakage paths of enclosure, the volume and flexibility of the enclosure envelop and objects within the enclosure. A sensitivity study is performed to examine the influence of these parameters on the dynamics of the internal pressure.
