Modelling of two-phase flow inside geothermal wells P. K. Chadha and M. R. Malin CHAM Limited, Bakery House, Wimbledon, London, UK A. Palacio-Perez Instituto de Ingeneria, UNAM Cd. Universitaria, Coyoacan, Mexico An extended homogeneous two-phase model is presented for the prediction of the two-phase flow of liquid and its vapor in a vertical well. Analysis of Two-Phase Flow Pattern Maps 8 3. Taitel and Dukler’s map Description of the map The Taitel and Dukler’s () map (Taitel and Dukler, ) is the most widely used flow pattern map for horizontal two-phase flow. This map is based on a semi-theoretical method, and it is computationally more difficult to use than other flow maps.
Two Phase Flow Modeling: Summary of Flow Regimes and Pressure Drop Correlations in The purpose of this report is to provide a summary of state-of-the-art predictions for two-phase ﬂows relevant to Advanced Life Support. The report is a follow-up on recommendation developed in the workshop by Chiara-monte and Joshi, where issues.

Summary. A comprehensive model is formulated to predict the flow behavior for upward two-phase flow. This model is composed of a model for flow-pattern prediction and a set of independent mechanistic models for predicting such flow characteristics as holdup and pressure drop in bubble, slug, and annular flow.

In the case of unsaturated flow, the role of the air phase could be ignored as its viscosity was low. This will not work any longer when two liquids are considered. The Lagrange method for numerical prediction of particulate two-phase flows is discussed and reviewed.

Abstract. The series of Workshops on Two-Phase Flow predictions was established in in theframework of a German/Yugoslavian cooperation projekt between the Lehrstuhl fürStrömungsmechanik, Universität Erlangen/Nürnberg, arid the Boris Kidric Institute ofNuclear Sciences, Belgrade, which is supported by the BMFT (Bundesministerium fürForschung und Technogie) and the.

In this paper numerical calculations of dispersed two-phase flows, based on the Euler/Lagrange approach, are presented with special emphasis on two-way coupling and turbulence modification. Proc. 6th Workshop on Two-Phase Flow Predictions, Erlangen (Germany), April An additional objective of the Workshop will be related to the validation of numerical predictions obtained by different model approaches and numerical codes.
These validations will be based on pre-defined test cases for which experimental or numerical results (e.g. direct or large eddy simulations) exist.
