Measuring device for internal thermal environment parameters of arc heater

Abstract

The invention discloses a measuring device for internal thermal environment parameters of an arc heater. The measuring device comprises cooling water inlets, cooling water outlets, cooling water channels, an air inlet structure, a measuring structure body, an inner-wall local heat flow measuring structure, an inner-wall temperature measuring structure and an inner-wall pressure measuring structure, the cooling water inlets and outlets include holes respectively, each cooling water channel is arranged between the cooling water inlet and outlet of the same group, the inner-wall local heat flow measuring structure is arranged between the cooling water inlet and outlet of different groups, the inner-wall temperature measuring structure and the inner-wall pressure measuring structure are arranged in the other side, and the air inlet structure is arranged in a measuring system. The internal thermal environment parameters of the arc heater are hard to measure due to the high-pressure and high-temperature environment in the heater. The measuring device can be used to overcome the difficulty in measuring the internal thermal environment parameters of the arc heater, and provides full data support for optimal design and operation monitoring of the arc heater.

Problems solved by technology

[0005] Due to the high temperature and high pressure environment inside the heater, it is difficult to measure its internal thermal parameters. Currently, only the internal pressure data can be measured.

Data on other thermal parameters are difficult to obtain
