Lack of precision and inconsistencies in existing correlations, an attempt was successfully made to develop a new and more mechanistically based correlation (Kattan, 1996 [1]) for boiling inside plain tubes. This new general correlation is original in that ...
The aim of this paper is to present the results obtained with a 3-D numerical method allowing the prediction of the cavitation behaviour of a centrifugal pump and to compare this prediction to model tests. The proposed method consists in assuming the cavit ...

Two-phase flow pattern data were obtained with 12.0 mm bore sight glasses for five refrigerants: R-123, R-134a, R-502, R-402A and R-404A. The existing flow pattern maps of Taitel-Dukler and Hashizume poorly represented the data while the VDI map identified ...
The conversion to the new alternative refrigerants caused by the greenhouse and ozone effects is now replacing nuclear reactor analysis and safety as the major driving force in two-phase heat transfer research. Extensive studies are underway on pool boilin ...
Flow pattern data for horizontal intube flow boiling are presented for refrigerants R-134a and R-402 (60/2/38). The flow pattern observations were compared with various criteria for determining whether the entire circumference of a horizontal evaporator tu ...
A mathematical model for the simulation of water airlift pumps is developed, based on the "interspersed continua" approximation for two-phase flow systems, together with an algorithm that selects the appropriate friction correlation for specific flow regim ...
A critical review of evaporation in plain, horizontal tubes is presented, focusing primarly on flow boiling correlations. Emphasis is placed on analyzing the integrity of currently accepted ideas and methods, identifying the weaknesses in current design me ...
