水平撞击流干燥器连续相的数值研究

The Numerical Simulation of a Coaxial Two-impinging-streams Dryer

对于撞击流的研究主要停留在实验研究阶段,然而,实验研究受到时间、实验环境、实验设备等因素的限制。本文试图采用数值模拟的方法来研究水平撞击流干燥器中连续相流场的特性。通过比较,发现数值模拟的结果符合现有理论,从而验证了所建模型的正确性,并为今后进一步的理论研究和设计开发打下基础。

Since the method of the study of Impinging Streams had its limitation, in this paper, the method of numerical simulation was used to investigate the flow characteristics of a coaxial two - impinging - streams （TIS） dryer. After the comparison of the results from the classic theory and numerical simulation, it was found that the numerical simulation method could succeed in simulating the TIS dryer. It was step stone for the further theoretical study and design of the Impinging Streams dryers.
