ASHRAE is conducting research to increase understanding of transition flows inside commercially available enhanced tubes. It approved funding totaling $986,953 for eight research projects in the areas of indoor air quality, comfort and health, energy conservation, operating and maintenance tools, environmentally safe materials, and design tools at its 2003 annual meeting earlier this year. Among them is 1280-TRP, Measurement and Evaluation of Single-Phase Heat Transfer and Pressure Drop Inside Enhanced Tubes for Transition Flow. The principal investigator is Josua Meyer, Ph.D., P.E., Department of Mechanical and Aeronautical Engineering, University of Pretoria, Pretoria, South Africa. The project is expected to take two years to complete at a cost of $76,750. The project is sponsored by ASHRAE Technical Committee 1.3, Heat Transfer and Fluid Flow.
