Problems solved by technology

[0005] However, the shortcomings of the above application are that the shooting and debugging of the device are relatively complicated, it is inconvenient for the experimenter to observe, the mixing of the gas components cannot be carried out, and the applicability of the device is relatively single, which cannot meet the diverse experimental conditions. cost too high
In addition, most of the existing single-droplet test benches have the problem that the flame is affected by the size of the chamber space or that although the chamber space of the test bench is sufficient, the chamber is not convenient for observation or shooting.

Description

technical field [0001] The invention belongs to the technical field of combustion experiment devices, and more particularly relates to a droplet evaporation and combustion device and an experiment method that are convenient for observation and shooting. Background technique [0002] Nanofluid is a new type of energy that is emerging to replace petroleum fuels, that is, by adding nano-scale particles to traditional fuels, the traditional fuels are modified, thereby improving the combustion efficiency of fuels, reducing the ignition delay of fuels, etc., but fuel The combustion process is divided into many stages. In order to further develop nanofluid fuels, it is necessary to further understand the properties of nanofluids. Therefore, it is very important to explore the effects of different types of nanoparticles, different sizes of nanoparticles, and different concentrations of nanoparticles on the combustion properties of nanofluids such as ignition delay and ignition tempe...
