Abstract

Abstract

In order to investigate the flow characteristics of isothermal jet into cross-flow for a safety characteristics,the effect region and the factors that contribute to the flow characteristics were studied.Based on the results,it can be concluded that the velocity ratio was the most important factor in this flow type.The calculations were agreed well with the visualization tests.injection（SI） inclined tube in the reactor cooling system,the numerical simulations were carried out at vari-ous velocity ratios between jet and main flow by using the commercial computational fluid dynamics software CFX.Via the computations,the 3-D flow traces of the typical operation condition were obtained,also the flow
