In the first stage of the atomization process, the critical wave number kmax with the fastest-growing amplitude is determined from the quadratic equation in k and includes a dependence on the kinematic viscosity of the liquid, the densities of the gas and liquid phases, the liquid/gas ...
who sought to characterize unsteady flow situations similar to those experienced during a sniff. In their model, the amplitude of an oscillating volume flow rate,Q, is related to the maximum pressureP, the radius of the channelrt, the kinematic viscosityμ, and the Womersley number Wo by the...
Density relaxation was set to 0.3, keeping the pressure relaxation unchanged (0.3). Modified turbulent vis cosity and turbulent viscosity were reduced to 0.5, with energy relaxation equal to 0.6. The mesh was deformed at a given time to move the plunger accordingly, which simu lated ...
