Abstract
In order to improve the heat transfer efficiency of the multi-channel dryer, based on the Navier-Stokes equations and the standard two equation kinetic-ε (epsilon) turbulent model, the Volume of Fluid model in fluent software was used to simulate the two-phase flow field of the condensation heat transfer in a micro-channel of dryer, the structural optimization and the influence of process parameters on the uniformity of temperature distribution were analyzed. The results showed that the saturated water vapor began to condense and release heat when it entered the channel, and with the flow of water vapor in the channel, the channel surface presented a certain range of temperature distribution, the condensate converged at the bottom of the channel and the liquid film gradually thickened along the channel. In general, the heat transfer coefficient of the multichannel dryer is high, and the temperature difference between the inlet and outlet of the channel can be reduced by the reverse convection heat transfer in the multi-channel dryer with double inlet, the relationship between the speed of dryer and the average condensation heat transfer coefficient shows an increasing trend of slope decreasing.
