Description
Technical Field
The invention belongs to the technical field of spray cooling and internal combustion engine spraying, and comprises a spray flow measuring and measuring liquid collecting device, wherein the device is used for measuring performance parameters such as spatial distribution of spray field flow.
Background
The spraying is a necessary process in the fields of spray cooling and internal combustion engine spraying, and the good spraying effect can not only obviously improve the heat exchange efficiency in the spray cooling process, but also fully atomize fuel in the internal combustion engine spraying process and improve the combustion efficiency. The flow distribution is one of important parameters for researching a spray field, and the distribution rule of parameters such as the flux of the spray field can be directly obtained through the flow distribution in the spraying process, so that the flow distribution is a focus of attention of numerous scholars.
Usually, a multipurpose test tube with a large flow rate of a spray field collects a liquid sample at a fixed point of the spray field, and a glass test tube wall is thick (about 1-2mm), so that a large error is generated, and the measurement precision is influenced. The liquid collection part of the experimental device adopts a matching mode of a stainless steel tube (hereinafter referred to as a metal test tube) with thinner wall thickness and a hose.
In the spray flow spatial distribution measuring process, more accurate flow distribution measurement needs a thinner steel pipe to divide a spray field, and working media can remain in the steel pipe or suspend in a drop at a metal test tube outlet due to the surface tension of the working media, so that the working media can not be accurately and completely collected, and larger errors are caused.
The measurement process of the spray field usually requires multiple movements of the experimental device to achieve the full measurement of the performance parameters of the spray field, however, each movement of the device requires recalibration and calibration of the device position to maintain it level and accurately move to the exact location of the spray field to be measured, which is time consuming and may create operational errors. The experimental device can accurately move and measure the flow of all positions of the spray field without moving after one-time position calibration is completed.
