다양한 형태의 미소 채널에서 격자 볼츠만 방법을 이용한 이상 유동 해석

Abstract

This reserch investigates the lengths of droplets and the spatial periods between droplets in micro channels of having separately different entrance types. The entrance types of micro -channels are T-type, cross type and Y-type. Latties Boltzmann method is used for analysis. Interaction potential LBM proposed by Shan and Chen appears to be effective for immiscible two-phase flow in micro channel. Experimental data by Joshua D. Tice et al is found to be in good agreement with values obtained from simulations. As a result of aimulation, the sizes of droplets are most short in cross type. The formations of droplet are influenced by the ratio of flow rate and shapes of inlets.
