Optimal and Nonoptimal Flows in a Swirl Atomizer

Liquid flow in a simplex swirl nozzle

“…With this criterion, the air core radius is found from roots of a third-order polynomial obtained from equation (24). It should be noted that in the case of high Re numbers, equation (24) takes the form of an inviscid solution (Craig et al 2009 andXue et al 2004). …”

“…Assuming that the tangential velocity of liquid is converted completely to the radial velocity at the nozzle exit (Taylor 1948, Craig et al 2009), the spray angle can be found as,…”
