RISAir-Side Surface Wettability Effects on the Performance of Slit-Fin-and-Tube Heat Exchangers Operating Under Wet-Surface Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A study of condensate retention and the attendant thermal-hydraulic effect associated with changes in air-side surface wettability is presented for a series of slit-fin-and-tube heat exchangers ...
A Numerical Study of Flow and Heat Transfer Enhancement Using an Array of Delta-Winglet Vortex Generators in a Fin-and-Tube Heat Exchanger
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work is aimed at assessing the potential of winglet-type vortex generator (VG) “arrays” for multirow inline-tube heat exchangers with an emphasis on providing fundamental understanding of ...

Fluid Flow and Heat Transfer at Micro- and Meso-Scales With Application to Heat Exchanger Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By their very nature, compact heat exchangers allow an efficient use of material, volume, and energy in thermal systems. These benefits have driven heat exchanger design toward higher compactness, ...
Flow Modes and Mode Transitions for Falling Films on Flat Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow mode transitions for a liquid film falling over flat tubes are studied for a wide range of conditions. Hydraulic oil, ethylene glycol, ethylene-glycol-water mixtures (at three different ...
