WebDuring venting of a runaway chemical reactor, the volume of the reactor contents rises or swells with the volume of gas and/or vapour bubbles formed within the liquid. The ability to model level swell is essential in order to determine how much liquid the disposal system must be designed to handle. WebAbstract.
