Heat transfer and pressure loss performances are experimentally studied for the flow through the pin-fin arrays, which consist of closely arranged very thin pins, in order to investigate the effect of turbulence on the heat transfer mechanisms. The flow visualization tests were carried out for ...
Flow phenomenon at the pin fin rear side and a leakage vortex near the pin fin tip were observed. High Nusselt numbers appeared on leading side. The leakage vortex imposed high energy losses in the mainflow. The flow and heat transfer characteristics were associated with Ro number and ...
Single-phase cryogenic (LN2) heat transfer using four diamond-shaped µPFHSs was characterized by Rasouli and Narayanan [1] in ReDh ranging from 108 to 507. The global heat transfer trends showed that, at a given Reynolds number (Re), heat sinks of same pin fin size and aspect ratio ...

2. In this study, a comparison between MEMS two-fluid heat exchangers with and without pin-fins is done for which the repeating unit of the MEMS two-fluid heat exchanger without pin-fin is identified as well and is shown in Fig. 2. Studies are done for a MEMS two-fluid heat exchanger...
Heat transfer from pin-fins situated in an oncoming longitudinal flow which turns to crossflow Experiments were performed to determine per-fin heat transfer coefficients for pin-fin arrays exposed to a novel airflow arrangement. The flow enters the a... M E.,Sparrow,and,... - 《International...
