In this research, flow pattern and pressure drop characteristics of kerosene-water two phase flow in horizontal mini-channel was investigated. The tube diameter was 0.53 mm, and it was made from pyrex glass. The volumetric fluxes of each liquids were set between 0.05 and 0.6 m/s. The several flow patterns were observed in mini-channel, i.e. Droplet flow, Slug flow, Slug-Annular flow, Annular flow, Parallel flow and Kerosene slug flow. The transition of flow pattern has been explained by using Weber number of each phase. The pressure drop has shown a good agreement with Lockhart-Martinelli correlation, moreover the adaptability of the moving film model to the estimation of pressure in the slug flow regime has been confirmed.
