Since the Fall of 1992, the University of Central Florida (UCF) and the Orange County Fire Rescue Division (OCFRD) have conducted a joint research program to evaluate the effectiveness of positive pressure ventilation (PPV) as a firefighting techniqu

Using simple fans, a structure can be slightly pressurized to provide rapid and effective removal of heat, smoke and toxic gases this technique is known as positive pressure ventilation (PPV). Both laboratory and live fire tests clearly demonstrate t

Understanding and predicting critical heat flux. (CHF) behavior during steady-state and transient conditions is of fundamental interest in the design, operation, and safety of boiling and two-phase flow devices. The results of a comprehensive study s

In this paper, a theoretical prediction of critical heat flux (CHF) during power transients in forced convective boiling is presented. The analysis is restricted to departure from nucleate boiling (DNB) type of CHF at low qualities. The developed the

This note presents a numerical model of inclined thermosyphon performance. Liquid-vapor interfacial shear stress and effects of working fluid inventory at various inclination angles are included within. Two important limiting mechanisms, dry-out and

An initial period of film boiling has been identified as a key element in the chain of events leading to a large-scale vapor explosion. From theoretical considerations, the conditions requi...

An analytical method is presented for predicting the minimum heater temperature and the minimum heat flux at the onset of film boiling for spherical and flat plate heaters in saturated and subcooled liquids. Consideration is given to a variety of fac

An in-pile power-cooling-mismatch (PCM) test designed to investigate the behavior of a nine-rod PWR-type fuel bundle under intermittent and sustained periods of high temperature film boiling operation was recently conducted. Emphasis was placed on de
