Fluidic flow refers to the liquid from the nozzle or orifice ejection, out of the solid boundary constraints, in the liquid or gas for diffusion flow. When the fluid is injected into the static environment, there are discontinuous planes with different speeds between it and the surrounding static fluid. The discontinuous plane will be inevitably interfered with, thus losing stability and producing vortices. The surrounding fluid enrolls into the jet, and constantly moves, deforms and divides into turbulence. Since the liquid flowing at high speed cannot be observed by conventional means, a high-speed camera is needed to record the morphometric changes of the fluid when it is shot into the static environment.
