【Abstract】 CFD software was used to numerically simulate the production and processing system of white tea, so as to obtain the distribution of air flow through the tea, and to improve the poor uniformity of air flow distribution in the system by adding variable cross section.The simulation results show that increasing the variable section and changing its tilt angle can effectively improve the flow uniformity of the system, and the system uniformity is the best when the tilt angle of the variable section is 15°.更多还原
