Abstract
- Numerical simulation of the flow field of chrysanthemum hot air drying chamber before and after optimization was carried out by using porous media model. To solve this problem, by setting the optimization scheme of the turbulence fan, the wind speed non-uniformity coefficient M in multiple sections was reduced from 125.51%, 149.27%, 144.81%, 135.63% and 106.45% to 90.44%, 116.15%, 86.92%, 77.49% and 76.67%, respectively. After flow field optimization, airflow velocity in the middle and rear of drying chamber increases significantly, and airflow uniformity in the whole space is improved.
