General review of flashing jet studies

WebThe only way to get a complete picture of the flow field is to analyze the ejector by a Computational Fluid Dynamics (CFD) approach. However, it must be stressed that CFD is not a design tool. The complete geometry of the ejector must be known in advance before any CFD analysis is attempted. WebJan 25, 2014 · The initial, flashing stage of the jet, where the system is furthest from equilibrium is least understood. To investigate theoretically these source processes, knowledge of accurate and reliable data such as distribution of droplet size, velocity and temperature is mandatory. These models are needed in design and safety assessment.
