Abstract

In order to study the distribution of airflow and built the movement model of airflow velocity in traditional Chinese-medicine solar drying chamber, the numerical simulation of three-dimensional steady-state model was carried out to analyze the effect of different wind speeds on the airflow distribution in drying chamber using computational fluid dynamics(CFD) software Fluent and the k-ε model. The results showed that, compared to the airflow speed of 2m/s and 10m/s, the internal wind speed and airflow distribution were better when airflow velocity was 6m/s.
