Computational investigations of flow and heat transfer in gas liquid slug flow in millimeter size channels

Abstract

In this thesis the flow and heat transfer in slug flow regime in small diameter channels under different conditions have been studied using computational fluid dynamics CFD using volume of fluid VOF method to capture the gas liquid interface The hydrodynamics of slug flow for a range of bubble volumes for equivalent sphere radius close to 1 between 0 72 1 55 keeping all other parameters constant has been studied in a periodic unit cell consisting of a gas bubble and two halves of adjacen...
