Title: Bubble boiling in flow of refrigerating media

Creator:

Bohdal, Tadeusz

2017

Type:

artykuł w czasopiśmie

Description:

The paper describes results of investigations of heat transfer and pressure drop during bubbly boiling of refrigerating media. In this article were presented of authors own experimental studies and were proposed new simple calculation model describing bubble boiling in the tubular channel. The author attempts to put forward a simplified description of the process of bubble boiling in a straight pipe. The two-phase one-component (liquid-vapour) system is treated as a continuum governed by the laws of conservation of energy, momentum and mass. The continuum is characterised by parameters that describe the two-phase system, such as density of the two-phase mixture, static void fraction or static equilibrium dryness fraction. In view of engineering applications, a one-dimensional model is used where physical quantities are cross-section averaged. This way the average velocity, pressure, temperature, and so on, are introduced. The results of the proposed model have been compared with the results of the experimental research with satisfactory compliance.
