This paper reports that the concepts of thermal drag and thermal clogging, etc. developed for single-phase thermal compressible flow were extended into gas-liquid two phase flow systems under heating, and used to investigate heating effect on fluid flow within such systems. An approximate analytical relation between thermal acceleration pressure drop and dimensionless heating number He was obtained based on these concepts and the compressibility Z of fluid was employed to conduct generalized analyses. Good agreements are reached by comparing its results with some existing data.
