Thermophysical properties of molten core materials (corium) are necessary input parameters models and computer codes which predict the severe accident progression in light water reactors. The corium contains components UO 2 , ZrO Zr Fe. measurement is a very challenging task due to high melting points can reach 3000 K. This paper presents density system for drop based on techniques aerodynamic ...

Abstract The gas content is one of the important factors in cavitation, which may increase pressure inside cavity through diffusive mass transfer dissolved into cavity. In present study, we try to directly measure sheet at throat a converging-diverging nozzle. Then influences flow velocity and (amount oxygen) on partial are investigated. It found that, even low level, slightly but apparently hi...

Abstract Systems with multiple jets are encountered in many engineering applications, for example, propulsion units aircraft and rockets. When more than one jet is placed close to each other, the resultant aerodynamics complicated due mutual interaction of jets. In present work, mean flowfield mixing characteristics free supersonic from twin triple converging-diverging nozzles proximity studied...

It is well-known that stationary transonic solutions of the compressible Euler equations are hard to compute using the stationary form of the equations. Therefore, time marching methods with explicit or implicit time integration are normally employed. In this paper a method is described that computes one-dimensional transonic flows directly from the stationary equations. The method is based on ...

For the study of transients in gas-liquid flows, the equations of the so-called separated flow model are inadequate, because they possess, in the general case where gas and liquid move at different velocities, complex characteristics. This paper is concerned with the equations of motion for bubbly flow. The equations are discussed with emphasis on the aspects of relative motion and the characte...

Abstract Jet-Electrochemical machining (Jet-ECM) is a novel variation of traditional electrochemical in which electrically conductive material removed through anodic dissolution by means fine jet electrolyte. In this study, the effect nozzle geometry on removal characteristics are investigated physical experiments performed Jet-ECM system under development at university Manchester. A total 8 no...

This paper describes the experimental study of the noise generating characteristics of high-temperature, shock-containing jets emanating from conic-section, converging-diverging (C-D) nozzles. Conic C-D nozzles consist of two conic sections, one contracting and the other expanding, joined to form a supersonic nozzle with a very sharp radius of curvature at the nozzle throat. An experiment is co...
