Fire Whirls and Building Aerodynamics
Numerical modeling of the behavior of fire and smoke within proposed building atria have revealed the possible presence of violent fire whirls or fire tornadoes induced by an inadvertent combination of ventilation and exhaust openings. Such fire vortexes can accelerate combustion up to ten times that seen during conventional fires, rapidly move fire and debris across available evacuation routes...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
From fire whirls to blue whirls and combustion with reduced pollution.
Fire whirls are powerful, spinning disasters for people and surroundings when they occur in large urban and wildland fires. Whereas fire whirls have been studied for fire-safety applications, previous research has yet to harness their potential burning efficiency for enhanced combustion. This article presents laboratory studies of fire whirls initiated as pool fires, but where the fuel sits on ...
متن کاملNumerical Study on Small-Scale Fire Whirl using Large Eddy Simulation
Fire whirl is a rotating fire with either a fixed or revolving flame centre-core caused by unbalanced entrainment. In general, the flame height of a fire whirl is significantly larger than that of a free standing fire. It is suggested by several studies that fire whirl is a disastrous scenario especially in urban or bush fires since it can greatly promote the fire spread and escalate the thread...
متن کاملThreat-Independent Column Removal and Fire-Induced Progressive Collapse: Numerical Study and Comparison
Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. This method is suitable especially in the case of blast-induced progressive ...
