摘要: Based on the Froude modeling concept, Heskestad proposed a set of scaling relationships for spray-plume interaction high droplet Reynolds number conditions (ReD ≥ 10). The is defined as ratio product diameter and absolute value velocity relative to gas over kinematic viscosity. Recently, Yu showed theoretically that methodology can be extended low ≤1) except requirement size. High in general prevail sprinkler applications usually take place water mist applications. To bridge gap, this paper describes generalization approach presents applicable interactions all conditions. These should experimentally validated before engineering
