Thermo-hydraulic study of inclined louvered fins
… the air side. To increase the heat transfer rate fins are added on the airside which increase the surface area. Over the past decades a considerable amount of research has been performed to improve the performance of fin-andtube heat exchangers: e.g. transfer the same amount of heat with a smaller …

Practical Applications of Delta Winglets in Compact Heat Exchangers with Louvered Fins
… industry in systems that cool engine components. Louvered fin heat exchangers are used over their continuous fin counterparts because of the significant advantages they provide in heat transfer efficiency, while only causing small increases in overall pressure losses. With the recent emphasis that …

Spatially Resolved Heat Transfer Studies in Louvered Fins for Compact Heat Exchangers
… heat transfer study of six scaled up louvered fin geometries that are typical of those found in modern louvered fin compact heat exchangers. Heat transfer measurements were performed over a range of Reynolds numbers and with two different boundary conditions. A fully heated boundary …

Evaluation of Internal Fin Geometry for Heat Transfer Enhancement in Automobile Exhaust Energy Harvesting Systems
… generators using two different internal fins — louvered fins and herringbone wavy fins. The multi-louvered fins basically have 'multi flat plate' behavior and will enhance the heat transfer by deflecting the air from its original path and aligning it with the plane of the louvers. …

Metal foams as novel materials for air-cooling heat exchangers
… is considered as a replacement for conventional louvered fins in brazed-aluminum heat exchangers. Closed-loop wind tunnel experiments are conducted to measure the pressure drop and heat transfer performance of metal-foam heat exchangers. In addition to characterizing the air-side pressure-drop …

Flow, Heat Transfer, and Pressure Drop Interactions in Louvered-Fin Arrays
… of the most common interrupted surfaces is the louvered fin. The goal of this work is to develop a better understanding of the flow and its influence on heat transfer and pressure drop behavior for both louvered and convex-louvered fins. Specifically, this research explores the end effects of …

Heat Transfer Measurements and Optimization Studies Relevant to Louvered Fin Compact Heat Exchangers
… contain tubes carrying one fluid and external fins through which passes another fluid. To enhance the fin-side heat transfer in a compact heat exchanger, which is typically the air side of the heat exchanger, louvers are manufactured into the fins. Louvered fins initiate the growth of new …

Measurements and Predictions of the Heat Transfer at the Tube-Fin Junction for Louvered Fin Heat Exchangers
… investigation, a scaled-up model of the louvered fin-tube wall was tested in a flow facility. Although computational results for the isothermal tube wall are shown, control of the experimental isothermal tube wall proved to be unrealistic and only heat transfer measurements along the …

Instability of flow boiling in parallel microchannels
… transient heat transfer problem of louvered fins bounded with multiport aluminum plates using commercial software (ANSYS FLUENT). While the fin geometry was kept constant in all simulations, two different multiport plate configurations (11 round ports, D=1.2 mm; and 22 square ports, …
