Tornado depressurization and air cleaning systems
Conference
·
OSTI ID:7338388
Results from analytical and experimental investigations of tornado depressurization effects on air cleaning systems are presented. Development and use of a computer code that simulates the internal pressures and flows within an arbitrary ventilation system is described. The formulation of fluid motion equations is based upon lumped component response, isothermal or adiabatic compression of air, and conservation of mass. A computer generated movie is shown illustrating the flows and pressures in a simple system. Also described are experimental investigations to determine air cleaning component response to high flow rates caused by tornado depressurization. HEPA filter is the principal component under investigation. A description of the experimental apparatus is given and preliminary test results presented.
