西部地区外部环境对集装箱内部温度场影响的实验分析
Experimental Analysis of External Environmental Influence on Internal Temperature Field of Containers in Western China
摘要
Abstract
In order to explore the influencing factors of the temperature field inside containers in western China,a three-dimensional unsteady mathematical model of the fluid inside the container was established.Simulation software was used to simulate the internal temperature field distribution,and experimental verification was conducted to validate the simulation results.Atmospheric temperature and solar radiation were considered as influencing factors,and regression analysis was performed on the experimental data.The distribution of the internal temperature field of empty and loaded containers under the same environmental conditions was studied.The results show that atmospheric temperature is the main influencing factor of the internal temperature field of the container,with a regression coefficient of above 0.9.Solar radiation,as a thermal load on the container wall,also causes local temperature changes.The stacking method of the cargo inside the container can lead to a temperature rise.The error between simulation and experimental data is within 3 ℃,proving the feasibility of the established simulation model.This provides a design reference for thermal insulation measures in container transportation.关键词
