Embodiment Construction

[0050] See figure 1 , a multifunctional gas wave cooling jet flow field display and measurement device implementing the present invention is mainly composed of an oscillating receiving tube 44, a main body 12, an upper bearing seat 19, a turntable shaft section 13, a jet nozzle 11, an optical glass 38 and an acoustic oscillator 45 and other parts. The main body 12 is made of a metal plate with a size of 100-120mm in thickness. A circular chamber with a depth of 70mm and a diameter of Φ200mm is processed downward at the center of the upper part of the body at a distance of 160mm from the left end line, so as to match the placement of rotating or stationary For the nozzle 11, a round hole of Φ40 is processed in the lower part for the shaft end of the nozzle shaft section 11 to protrude from. The shaft end is connected by a key to install an assembly composed of a small pulley and the speed measuring gear 1. The counting gear 1 is composed of 60 Composed of four teeth, manufact...

Abstract

A kind of multiple functions gas wave cooling effluxion flow filed display device and measuring method which belongs to technique field of effluxion of pressure gas and expanded cooling and measuring control. The invention adopts integrated structure and works when running and static and possesses window for view and shooting image, it can analogue working mechanism and performance of multiple types of gas, and provides platform for leading high-precision PIV to wave mechanical flow filed measurement, and measures important parameters in-phase, and fulfills requirement of experiment, and accomplishes research content of changing condition, experiment component, rotate speed, two phases of gas and liquid, and accomplishes important experiment of best matching of structure and parameter. The structure is reasonable and easy, operation is convenient, and performance is stable and reliable. It fits for multiple functions gas wave cooling measuring filed of changing condition and research content.

Description

technical field [0001] The invention belongs to the technical field of jet flow and expansion refrigeration and measurement control of pressurized gas. Background technique [0002] Gas wave refrigerator, Chinese patent 89213744.4 and multi-stage gas wave refrigerator, invention patent 96115022.X, belong to one-time and multiple unsteady expansion refrigeration, all of which use a certain rotation speed to send the gas medium to the ends around the ring body in turn The closed receiving tube jet makes the resident gas in the tube do unsteady expansion work. Multi-stage gas wave refrigerator is a new type of refrigeration equipment developed on the basis of single-stage gas wave refrigerator. It is suitable for large flow and large expansion ratio working conditions, and has the characteristics of high efficiency and wide application range. Multi-tube jet flow oscillation refrigerator, has obtained utility model patent, invention patent to be authorized, application number: ...
