Heat Transfer in Gas–Liquid Flows Through Wire-Mesh Packing

Abstract

This article presents the research on the air–water system flowing in a pipe section with electrical heating with a wire-mesh bed inside it. The heat flux was determined and so was the convective heat transfer coefficient for the two-phase flow through a pipe length that had been completely or partially filled with the wire-mesh packing. The packing level was found to strongly affect the heat transfer potential. Also, the dominant role was identified for a liquid in the heat exchange process under two-phase gas–liquid flow through the wire-mesh packing.
