...L. Wilson; Arunn Narasimhan; S. P. Venkateshan Hydrodynamic experiments measuring longitudinal pressure-drop versus flow rate are conducted for turbulent flow of air (channel hydraulic diameter based Reynolds number range of 2300 to 6860) through near-compact heat exchanger models with rod bundles...

...B. Prabhakara Rao; Sarit K. Das A detailed experimental study on flow maldistribution from port to channel of a plate heat exchanger is presented. In general, flow maldistribution brings about an increase in pressure drop across the heat exchanger. This increase is found to depend on flow rate...

...J. H. Nie; B. F. Armaly; W. Q. Tao; Q. W. Wang Measurements of three-dimensional turbulent flow in the exit head section of a shell-and-tube heat exchanger were performed using three-component laser Doppler velocimeter. The test geometry is half of a hemispherical cap with two outlet-tubes...

...F. Dupont; C. Gabillet; P. Bot The isothermal flow in a model channel of plate-fin heat exchanger with periodically arranged embossed-like vortex generators is investigated. Velocity measurements are performed by LDA in the transitional regime (Reynolds number from 1000 up to 5000). Strong...
