Numerical Investigation on the Gas Field Generated by High Pressure Gas Atomizer Focused on Physical Mechanisms of Gas Recirculation and Wake Closure Phenomenon
Physical mechanisms of gas recirculation and wake closure were investigated by modeling the gas field generated by High Pressure Gas Atomizer using computational fluid dynamics.A recirculation mechanism based on axial and radial gas pressure gradient was proposed to explain the gas recirculation.The occurrence of wake closure is regarded as a natur
