Abstract

The invention discloses a high-temperature, high-pressure and high-turbulent-flow single-liquid-drop evaporation experiment device and a method thereof, wherein the device and the method belong to the field of internal combustion engine combustion testing technology. The device comprises an air supplying device, an evaporation constant-volume elastomer member (14) which is connected with the air supplying device, a fan (5) and a telescopic liquid drop suspension device (7) which are arranged in the evaporation constant-volume elastomer member (14), and a control unit (2) which is connected with the evaporation constant-volume elastomer member (14). The fan (5) comprises a transmission and a mounting supporting device therein. The constant-volume elastomer member (14) comprises a fan mounting port (19), an observing window (24), a pressure sensor (6) and a temperature sensor (8). The high-temperature, high-pressure and high-turbulent-flow single-liquid-drop evaporation experiment device and the method thereof can realize evaporation characteristic experiment research on the small liquid drop in different turbulent flow conditions.

Description

technical field [0001] The invention relates to the technical field of combustion testing of internal combustion engines, in particular to an experimental device for high-temperature, high-pressure, high-turbulence single droplet evaporation. Background technique [0002] The development of internal combustion engine technology not only brings material civilization to human beings, but also has a huge impact on the environment on which human beings live. With the worldwide energy crisis and environmental pollution becoming more and more serious, people have increasingly stringent requirements for engines to save energy and control pollutant emissions. Therefore, research on clean alternative fuels is the most effective measure to solve the energy crisis and environmental pollution. Research on alternative fuels must improve its combustion characteristics, and the fuel-air mixing characteristics of fuel are the key factors restricting combustion performance. Further, the fue...
