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 к-ε 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 wer...
