Air pressure transient generation as a result of falling solids in building drainage stacks: definition, mechanisms and modelling

The consequences of air pressure transients in building drainage and vent systems (DVS) can be serious, as they compromise the integrity of the appliance trap seal - the last line of defence between the potentially hazardous foul air in the drainage and sewer network, and the habitable space within buildings. Pressure transients are caused by rapid changes in flow conditions in fluid systems. Much previous research has defined the nature and effect of air pressure transient generation and propagation on the air pressure regime within DVS. This paper confirms that falling solids have an effect on the pressure regime in a vertical stack; that transients are generated and that pressures are modified in a way hitherto undefined.
