Abstract
Aimed at the special condition of fluidic dynamic seals of high speed fluid machineries such as the aero-engine, a new type of sealing form, gas face and cylinder film seal was proposed. According to the structure characteristics of the gas film seal, the mathematical analysis model of the gas face and cylinder film seal was built. Then the model of gas film's three-dimensional flow field was numerically calculated by Fluent in the form of turbulent flow. The influence of sealing geometry structure parameters on the stability performances of the seal such as face opening force Fd, cylindrical opening force Fc, leakage Q, and friction torque M was studied. The geometry structure parameters include gas face film thickness, face groove depth ratio, cylindrical film thickness, cylindrical eccentricity, cylindrical groove depth ratio, and cylindrical groove width ratio.
