A detailed unsteady numerical simulation has been carried out to investigate the shock and unsteady flow in the low pressure (LP) rotor in a 1+1/2 counter-rotating turbine (vaneless counterrotating turbine (VCRT)).

Two-dimensional (2D) unsteady numerical simulation has been applied to study the effect of the variation in relative circumferential positions of rotors on the performance of a low speed compressor.

In this paper, a series of numerical simulations of bowed rotors with different lean angles are carried on.

According to principle of adjustable rotating blade fan and common characteristics of faults occurred freguently,swing faults of rotating blade in axial-flow fan of Qinhuangdao Power Generation Co.

In order to improve blade reliability under wet steam condition and prevent blade failure from liquid corrosion, the numerical model which can be used to analyze three dimensional, two-phase compressible turbulent flow field has been developed under rotating coordinate system, and it is adopted to investigate the water drop motion of a wet steam stage.

Reliability improved design of C50-90 steam turbine moving blade;

In air-cooled steam turbine, peak regulating steam turbine and the low pressure part of cogeneration unit operating under low volume flow conditions, the reverse flow in hub region of last rotor blade will carry water drops of wet steam in exhaust hood back to moving cascade passage, and cause moving blade trailing edge erosion and in turn fatigue crack.

This article describes how the wiser finalize the machining steps and tools considering the characteristic of M701F heavy-duty gas turbine compressor 13 stage moving blade,by using mastercam and Pro/E software,to construct the model.

Using the Dual-Time Stepping Method with Moving-Grid technique to solve the Navier-Stokes equations, the numerical analysis of the unsteady aerodynamics on vibrating cascade is performed.
