Computer simulation for the process of thermal response of LPG tanks based on high-temperature environment

To forecast the thermal response of LPG ( liquefied petroleum gas ) storage tank under the conditions of a non-normal thermal environment is of great practical significance to the evaluation of gas storage and transportation security, especially on disastrous accident prediction. This paper is based on the relationship between conservation of mass and energy conservation to describe the physical model and mathematical model of tank of LPG storage tank thermal response under high-temperature environment. And to have the theoretical analysis on the process from the high temperature environment to the internal heat transfer medium and the confirmation of the system pressure, and use the finite difference method to solve the mathematical model for thermal response of the liquefied gas storage tank, and found the rule of change of the pressure, temperature, density and quality under liquid region and the gas zone. The Object-oriented, visualization of visual c++ software was used to develop the numerical simulation software of the liquefied gas storage tank thermal response under the environment of high-temperature. This software is used to calculate the numerical value of the thermal response and the curve simulation of liquefied petroleum gas storage tank under the different flame environment, the different shape of the container, and the filling of the volume of different media etc.
