hiTRAN.SP upgrade to version 4.1.0 is released

Have you ever wondered how hiTRAN works, please take a look at our hiTRAN flow video clip below. Here you can see a repeat of the Reynolds flow experiment with hiTRAN Elements.

Site update
 In case you are a native German speaker, please have a look to our updated page for Germany with three sections:

• Teil 1 : Überblick über die Funktionsweise von hiTRAN Turbulenzerzeugern

• Teil 2 : hiTRAN Turbulatoren zur Leistungssteigerung in Kondensatoren

• Teil 3 : Wärmeübertragung und Ablagerungsbildung in Rohren mit Turbulenzerzeugern

Research:

• Cal Gavin is currently undertaking hydrodynamic and thermal experiments on Falling Film Evaporators equipped with hiTRAN Matrix Elements. The first results with respect to heat transfer are promising. Hydrodynamic tests indicate that for flows especially in the laminar and transition regions turbulence is increased considerably, as seen in the picture below. A final report is expected for the end of this year. If you are interested in the results please contact Cal Gavin.

_______ laminar flow

_______ pseudo turbulence flow

• Another focus of Cal Gavin's research is currently directed to the the hydrodynamic changes in single phase flow induced by hiTRAN turbulators. This is a project in collaboration with Birmingham University carried out by Alex Smeethe a research Student at Calgavin. In the picture below an example is shown of how the flowfield is changed by the use of hiTRAN Turbulators. Note the much higher velocity at the tube wall compared to a plain tube case!
