Résumé

Tube bundle heat exchangers are widely installed in industrial refrigeration plants. However, there is lack of data and correlations for the design of these apparatus, because the physical phenomena of the heat and momentum transport processes, especially in two phase systems, are not well established. A new test facility is designed by the department of Technical Thermodynamics at the University of Kassel to investigate heat and momentum transfer in horizontal single tubes with hydrocarbons at high pressures in saturation state. The adiabatic two phase flow and condensation are investigated. Therefore the flow patterns, pressure drop and heat transfer are determined for a wide range of saturation pressure, mass flux and vapour quality. Furthermore the influence of the surface structure on the pressure drop is also examined.
