SINGLE & TWO-PHASE FLOW IN SAFETY DEVICES
CANCELLED
The objective of this 4-day lecture series is to provide a state-of-the art of flow modeling of control and safety devices with peculiar emphasis given to safety relief valves. Proper sizing and design of such equipment requires knowledge of flow and thermodynamic conditions upstream and downstream of the device, physical and thermal properties of the fluid(s). It is worth noting that two-phase flow is now frequently encountered in various relief processes. This situation becomes considerably more complex due to the large number of variables associated with the interaction of the phases and possible flashing occurrence.
Experts coming from the scientific, industrial and technological communities will discuss their day-to-day experience in flow testing and CFD simulation exemplifying, nuclear, chemical and cryogenic applications.
The lectures are intended to accommodate attendees of both novice and advanced levels of technical expertise.
