Proc. ASME. GT2021, Volume 9A: Structures and Dynamics — Aerodynamics Excitation and Damping; Bearing and Seal Dynamics; Emerging Methods in Design and Engineering, V09AT23A005, June 7–11, 2021
Paper No: GT2021-58818
.... Dynamic mode decomposition (DMD) is applied to analyze the transient pressure on vibrating blade surface. Dominant flow structures like shock wave oscillating and corresponding frequency on blade surface can be acquired through DMD method. TWM simulation with DMD analysis indicates that the shock wave...

... in the cascade passage. In addition, a practical high pressure turbine stage is generally driven under transonic flow conditions where the shock wave strongly influences the pressure distribution on the endwall. Therefore, it becomes very important to clarify the effects of the shock wave formation...

... by deploying shock waves in a transient process. The operation principle is based on the shock tube where shock waves, rarefaction waves and contact waves result from the mix- ture of fluids with different levels of total pressure. The incorpo- ration of a wave rotor into a gas turbine increases the machine...

... and by reducing the driven section diameter. The influence of the two factors on shock presence and shock formation was analyzed separately. Tests were carried out for driver-to-driven pressure ratios of up to 22, obtaining shock waves at Mach number of up to 1.70 with a difference from the theoretical value...

... pressurized water to pressurize, desuperheat, and condense the refrigerant vapor — all in one dynamic process. The underlying phenomena of flash evaporation, shock wave compression, desuperheating, and condensation inside the wave rotor channels are described in a wave and phase-change diagram...

... particle image velocimetry (PIV). Shock waves in both flows were clearly observed. The effect of flow rate on a 3D configuration of shock wave at the inducer and a so-called rotor-stator interaction between a rotating impeller and a stationary cascade were discussed based on a phase-averaged measurement...
