Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings. While illustrations of parameters including particular values may be provided herein, it should be understood that parameters need not be exactly equal to the corresponding values, but rather may approximate the values within acceptable error margins or design constraints.
[0030] In one exemplary embodiment of the invention, a casing handling system is provided. The casing processing system includes: a plasma exciter, which is arranged on the periphery of the compressor casing in a non-axisymmetric manner, and is used for generating plasma to accelerate the air in the compressor casing.
[0031] In this embodiment, by applying non-axisymmetric plasma excitation with appropriate intensity and frequency at the fixed pos...

Abstract
The invention discloses a cartridge receiver processing system which comprises a plasma actuator. The plasma actuator is arranged on the periphery of a cartridge receiver of a gas compressor and above movable vanes of the inner side of the cartridge receiver of the gas compressor in a non-axial-symmetry mode. The plasma actuator is used for generating plasma and accelerating air nearby the plasma actuator. Due to the fact that plasma incentive with proper strength and frequency is exerted on the fixed position of the cartridge receiver of the gas compressor, on the one hand, the cartridge receiver processing system has the effect of broadening a stable operation area of the gas compressor, on the other hand, the cartridge receiver processing system can improve a flow state of a leaf apex area, has the effect of reducing flow loss, and enables leakage flow loss and mixing loss of the leaf apex area to be in a lower level all the time.
Description
technical field [0001] The invention relates to the technical field of fluid delivery in fluid dynamics, in particular to a casing processing system, which can be used in aviation, chemical industry, power generation, metallurgy, electric power, transportation, textile and other industries. Background technique [0002] As we all know, in my country's basic industrial fields (chemical industry, power generation, metallurgy, electric power, transportation, textile, etc.), there are a large number of fluid conveying machines with blades (axial flow, centrifugal, and a mixture of the two) as the aerodynamic structural elements. Includes gas compressors, ventilators, blowers and compressors. In addition, in the field of aviation, fans and compressors are one of the core components of aviation turbofan engines. To improve the thrust-to-weight ratio and stability of aviation turbofan engines, it is necessary to increase the stage pressure ratio, aerodynamic stability margin and eff...
