Embodiment Construction

[0026] specific implementation plan

[0027] combine figure 1 Further introduce the composition of the air motion load simulation experiment platform. The high-speed rotation of the experimental platform requires the experimental device to have a very solid cement foundation. Both the motor 5 and the turntable 3 are fixed on the frame 1, so as to ensure that the whole platform is firm and stable when running. The turntable 3 is connected with the frame 1 through bearings, the central axis of the turntable 3 is connected with the motor 5 through the belt, the motor 5 drives the platform to rotate at high speed through the belt, and the speed of the turntable is obtained by the instant speed measuring device, so as to know the size of its dynamic load . The rotating speed of motor 5 is controlled and regulated by the frequency converter, and the frequency converter is installed outside the platform. Because what motor 5 has used is three-phase power line, so the electric wir...

Abstract

The invention provides a vapour condensation test method and a device by using a rotary stage to simulate the state of air movement load, belonging to the technical field of two-phase flow test. The movement load is obtained by stimulation of a ground rotary stage, and air dynamic load with different magnitudes can be obtained by regulating the rotary speed of the stage. The method mainly comprises the following four parts: a rotary table, a steam circuit, a coolant circuit, and experiment test and data acquisition storage equipment. The method and the device can simulate and research vapour condensation on air movement load in ground condition.

Description

technical field [0001] The device and method for ground simulation of steam condensation test under air motion load belong to the field of two-phase flow experimental measurement technology, and involve the new technology of ground simulation platform for air motion load, steam generation and condensation method, photographing of steam condensation process, and fluid parameter measurement method. Background technique [0002] Aerospace technology is an important symbol of a country's technological development level. In the field of aerospace, although the installation of high-power and highly integrated electronic and electrical equipment has improved the overall performance and combat capability of the aircraft, it has brought a heat load of tens of kilowatts, which is dozens of times the original, causing the air The circulation system struggled to meet the cooling requirements of its equipment and needed better energy management and refrigeration systems. The two-phase f...
