“…Simões Moreira and Bullard (2003) modeled high-speed jets emanating from short nozzles, where expansion waves formed downstream of a liquid core. They applied the solution of a Chapman-Jouguet wave to the process of flash-boiling and predicted choked flow downstream of the wave.…”

“…Examples include cavitation in automotive fuel injection systems (Martynov et al, 2006), liquid flashing and gas condensation during operational or emergency venting of hydrocarbon pipelines (Ettouney et al, 2012), flash boiling of water during loss-of-coolant accidents in nuclear reactors (Nigmatulin and Soplenkov, 1994) and liquid boiling and expansion in refrigeration systems and heat pumps (Simões-Moreira and Bullard, 2003).…”

Simulation of two-phase flow through ducts with discontinuous cross-section

The development of an AUSM+-up based scheme for simulating transient single or two-phase flows through ducts with discontinuous or abrupt changes in area is presented. The non-conservative terms in the governing equations arising from the variation in the duct area are discretised to maintain exactly states at rest. An additional scaling of the pressure based dissipation is added to ensure numerical stability across the area change. The extensive application of the scheme to ideal gas and two-phase CO 2 based on the Homogeneous Equilibrium Model (HEM) for both shock tube and other transient flow problems indicate the scheme's capability to resolve such problems accurately and robustly.

“…Examples include study of cavitation in automotive fuel systems (Martynov et al, 2006), flash boiling of water during loss-of-coolant accidents in nuclear reactors (Nigmatulin and Soplenkov, 1994) and liquid boiling and expansion in refrigeration systems and heat pumps (Simões- Moreira and Bullard, 2003). In the particular context of Carbon Capture and Storage, the focus of such models has been on the flows resulting from pipeline decompression and failure (Brown et al, 2013b;Mahgerefteh et al, 2012;Munkejord et al, 2010).…”
