【Abstract】 A two phase turbulence model and hybrid finite analytic method (HFAM) are used to predict the behavior of bubbly jet in static environment. It has more strong prediction ability than integral method relatively. The agreement between the calculated results and experimental ones show that the turbulence model and HFAM are effective and proper.更多还原
