Method for predicating combustion intensity of cigarettes based on detection of flow field distribution

Abstract

The invention discloses a method for predicating the combustion intensity of cigarettes based on detection of flow field distribution. The method comprises the following steps: determining air flow ofa combustion cone end in a smoking process of a cigarette sample by utilizing a flow detection device; determining combustion surface temperature under a corresponding smoking sequence of the cigarette sample by utilizing an thermal infrared imager and extracting all temperature data; recording a product of a temperature average value and data quantity as a dependent variable y; taking the air flow of the combustion cone end in the smoking process of the cigarette sample as an independent variable x to obtain a regression equation of a prediction model; after determining the air flow of the combustion cone end in the smoking process of other cigarettes, substituting into the prediction model, so as to obtain the predicated combustion intensity of the cigarettes. According to the method disclosed by the invention, an experiment process for determining cigarette combustion property parameters is simplified and a detection method of the combustion intensity is supplemented; unstable factors in the determination of combustion temperature are reduced, and a data processing process and the working amount are simplified; the detection efficiency is improved and basic data is provided forguiding cigarette material researches, cigarette combustion and smoking mechanism analysis and cigarette material designing.

Description

technical field [0001] The invention relates to a method for predicting the burning intensity of cigarettes, in particular to a method for predicting the burning intensity of cigarettes based on detecting flow field distribution. Background technique [0002] With the continuous development of technology in the tobacco industry, more and more attention has been paid to the characteristic parameters of the cigarette burning process, such as the temperature distribution of the cigarette when it is burned. The temperature distribution during cigarette burning not only affects the chemical composition and content of the main and side stream smoke, but also has a close relationship with the density, draw resistance, air permeability of cigarette paper, and tipping paper. Therefore, an in-depth study of the temperature field distribution during the burning process of cigarettes, and the connection of the temperature field distribution with the draw resistance of cigarettes and the...

Problems solved by technology

The first method is to use infrared imaging to detect the surface temperature of the cigarette combustion cone; the second method is to use a thermocouple to detect the internal temperature of the cigarette combustion cone. In this method, the thermocouple is in direct contact with the measured tobacco, which will affect the measured cigarette sample. environment of

In addition, the workload of data extraction in the later stage of the test of these two methods is heavy, especially when performing large-scale measurements, it often takes a lot of time and cost, and it is not "quickly waiting"
