The invention discloses a gas-phase temperature-measuring probe suitable for gas-liquid two-phase flow, which belongs to the field of flow field temperature testing. A gas-phase temperature measuring probe suitable for gas-liquid two-phase flow, including a blunt body structure, a hollow tube is provided on the leeward side of the blunt body structure, a baffle plate is arranged in the hollow tube away from the blunt body structure, and the hollow tube is close to the blunt body. A flow hole is opened on one side of the body structure, and a first thermocouple is arranged in the hollow tube close to the blunt body structure. The gas-phase temperature measuring probe suitable for gas-liquid two-phase flow of the present invention can generate the separation of gas-liquid two-phase flow without external power, and the position of the first thermocouple is based on the difference in inertia to generate gas-liquid two-phase flow The liquid phase is separated, the liquid phase is filtered out through the blocking of the baffle plate, and the liquid phase is filtered out through the flow hole under the action of gravity, which ensures that the temperature of the gas phase measured by the thermocouple is not disturbed by the liquid phase, and the accuracy of the test result is high.
Description
technical field [0001] The invention belongs to the field of flow field temperature measurement, in particular to a gas-phase temperature-measuring probe suitable for gas-liquid two-phase flow. Background technique [0002] Gas-liquid two-phase flow widely exists in the fields of energy, chemical industry and national defense power technology, such as jet precooling of turbojet engine inlet, premixing and combustion of liquid fuel and air in aero-engine, gas turbine intake humidification and other processes. Accurately obtaining the temperature distribution characteristics of the gas-liquid two-phase flow field is the basis and key to study the gas-liquid heat and mass transfer characteristics and optimize the two-phase flow process organization. In the gas-liquid two-phase flow field, due to the influence of the droplet phase, it is difficult for non-contact optical measurement methods and conventional contact thermocouple probes to accurately measure the gas phase temperat...
