Description

The HXFLOW code predicts three dimensional distributions of all flow parameters on the shell side of the TEMA shell & tube heat exchangers. HXFLOW can be used for design optimization, comparative evaluation and performance predictions (including the study of detailed flow distributions to identify potential problem areas). To aid in tube vibration analysis, an option exists to calculate and print tube gap velocities around the lengths of up to ten selected tubes.

The HXFLOW code consists of three distinct modules: HXGEOM – the geometry pre-processor module into which all required geometrical data are read and processed; and HXSOLVER – the thermal-hydraulics module where all flow computations are made and CFD-VIEW-module for the graphical display of all results.

The salient features of the code are summarized below: TEMA E, F, G, J type Shell and Tube Heat Exchanger; 30 degree, 45 degree, 60 degree and 90 degree tube layout; Single and Double segmental baffles; Impingement Plate included in the model; All data input using a Graphical User Interface, where the user is guided by numerous on-screen sketches; Capability to revise the grid density used for the solution process; Capability to obtain both parallel-to and cross-flow velocity distribution along any tube in the tube bundle; Graphical and numerical display of the results
