茶园风力除虫机通风管道三维数值模拟
Three-dimension numerical simulation of ventilation pipe of a wind-driven insect-killing machine for tea garden
摘要
Abstract
In order to get uniform velocity distribution of airflow across the outlet, ventilation pipe structure of tea wind-driven insect-killing machine for tea garden was improved and optimized and the Reynolds-Averaged N-S equation in fluid mechanics, the Simple Algorithm for Flow and k-e turbulence model were applied to calculate the numerical simulation model of ventilation pipeline using the Fluent software. With flow rate of the medium-pressure blower being 16 m3/min, the internal flow characteristics of ventilation pipe under no-load condition were obtained. Numerical analysis indicates when the distance between the two air inlets is 280 mm, the velocity distribution of airflow across the outlet is uniform.关键词
