马铃薯气调集装箱内换热与气体组分浓度变化的数值模拟研究
Numerical Simulation of Heat Exchange and Gas Component Concentration Changes in Modified Atmosphere Containers for Potato
摘要
Abstract
This study aimed to deeply explore the key factors of potato storage environment in modified atmosphere containers through numerical simulation methods,providing a theoretical basis for the optimization and application of modified atmosphere container technology in Inner Mongolia.Using the computational fluid dynamics(CFD)method,combined with porous media theory and user-defined function(UDF)programming,a three-dimensional transient numerical model considering the respiration and metabolism ef-fects of potato was established.On this basis,the effects of different air supply speeds(2.000 m/s,5.000 m/s,and 6.000 m/s)on the airflow velocity field,oxygen and carbon dioxide concentration distribution,and temperature evolution process were studied.The simulation results showed that the air supply speed had a significant impact on the flow field structure and gas concentration dis-tribution,and the air supply speed of 5.000 m/s could achieve more uniformity between gas distribution and temperature field on the basis of balancing energy consumption and gas displacement efficiency.In terms of airflow distribution,the high-velocity jet and forced convection near the inlet caused the gas concentration to change drastically,while the middle and rear regions showed a gradu-al slowdown of concentration gradient and a stable trend of temperature.This study clarified the main transport mechanisms in the gas transport process,revealing its influence on the uniformity of the storage environment,and providing a scientific basis for the ap-plication of potato modified atmosphere container storage in Inner Mongolia.关键词
