摘要
Abstract
As a new generation of drying equipment, swirl medium time dryer (SMTD) has a simple structure, high efficiency, and large capacity. It is becoming a new trend of the research of gas-solid mo-phase flow drying technology. The computational fluid dynamics (CFD) software package Fluent was used in the numerical simulations of flow field inside the SMTD dryer. Reynolds stress model (RSM) was used to simulate the gas flow.The results indicate that the airflow in each drying chamber of cyclone dryer mainly swirls before it passes through the rotating stream tray where back-mixing is dominant. The distribution of tangential velocity is “S” type that the speed gradually increases to reach a peak from center to beth sides and then decreases. Axial velocity is dominant at the opening of the rotating-stream.关键词
