基于CFD的热风干燥饲料过程内流场均匀性研究
Uniformity of Flow Field in Hot Air Drying Process of Feed Based on CFD
摘要
Abstract
To study the distribution characteristics of the internal flow field of the drying oven in the process of hot air drying feed,FLUENT software was used to analyze the uniformity of the internal flow field of the feed drying oven by taking the air inlet and outlet mode of the drying oven,the air inlet velocity and the thickness of the feed layer as variables,and the turbulence uniformity and wind speed uniformity of the drying oven as the object.The influence of different factors on the internal flow field distribution of the feed drying oven was studied.The results showed that the opposite side wind energy significantly reduced the turbulence intensity and improved the turbulence uniformity.When the wind speed was constant,the uniformity of wind speed on the upper surface of the feed layer was proportional to the thickness of the feed layer,and the uniformity of wind speed on the lower surface was inversely proportional to the thickness of the feed layer.When the thickness of the feed layer was constant,the uniformity of the wind speed on the surface of the feed layer was inversely proportional to the wind speed at the inlet.This study provides theoretical guidance for improving the uniformity of the flow field in the drying oven.关键词
