Abstract

There is a scarcity of data and theory currently available regarding the heat transfer coefficients associated with two-phase, multicomponent mixtures at cryogenic temperatures. This paper presents results of research aimed at measuring the convection heat transfer coefficients for hydrocarbon mixtures (methane, ethane, propane, and nitrogen (for dilution)) during evaporation while flowing within a heated horizontal pipe over a wide range of temperatures (from 100 K to room temperature). The results show the heat transfer coefficients along with their sensitivity to parameters such as heat flux, mass flux, pressure, and composition. (C) 2014 The Authors. Published by Elsevier B.V.
