چکیده
Serving as a key component of the core engine, high-load axial compressor is expected to have high performance, which determines several critical parameter levels aero-engine. The unsteady effect on performance induced by interaction among different rotors should not be ignored during design compressor. between R1 (the first rotor row) and R2 second transonic was measured in detail using high-frequency pressure fluctuation sensors, aiming reveal evolution distribution characteristics sweep inside passage. results show that near choke points, oblique shock wave at leading edge high-pressure region blade side triggers R1-2BPF (blade passing frequency) disturbance, from traditional harmonic wake disturbance. A ‘long tail’ flow structure, indicates major influence wave, obviously reaches exit influences upper part S1 R2. combination R1-1BPF (mainly caused disturbance) field significantly, both them sharply grow middle rear parts passage where strength two disturbances increases 24% 68%, respectively, compared Moreover, circumferential non-uniformity significantly increase some locations exit, attributed relative clocking positions blades.

Application of Analytical and Numerical Methods for the Design of Transonic Axial Compressor Stages
Usually, the first stage of a compressor of a gas turbine works in the region of transonic flow, so that the designer has to take into account a lot of flow details like shocks, boundary layer separation and their interaction, when a new machine is defined. Beside other problems the choice of the blade geometry and profile family is one important consideration. For the design of the blades anal...
متن کاملUnsteady Transonic Flows in an Axial Flow Compressor*
Introduction. This paper deals with some transonic flow problems for the supersonic axial flow compressor: these arise in connection with flutter analysis for fan blading. Very detailed solutions for unsteady plane transonic flows through a cascade of flat plates have been given by Goldstein Braun and Adamczyk (1977) and Nagashima and Whitehead (1977), see also Goldstein (1975), Kurosaka (1974)...
متن کاملEffect of aging and manufacturing tolerances on multi-stage transonic axial compressor performance
The Axial compressor is an integrated part of a gas turbine. The central part of compressors is its blades. Blade aerodynamic has a significant effect on compressor performance. Because of the adverse pressure gradient in the compressor, any deviation in the blade profile has a significant influence on the flow field as well as the compressor performance. During the manufacturing and operation ...
متن کاملNumerical And Experimental Analysis Of A Linear Compressor
The paper presents the study of a new compressor for household appliances, developed through a virtual simulation system, with Simulink and Adams software. Linear compressor has a linear motor coupled to a mechanical system: a piston and a spring. The advantage of this compressor respect to a standard reciprocating compressor is due to the high reduction of energy losses and variable capacity p...
