Leading Edge Cooling Performance of an Integrated Cooling Configuration

Volume 4: Heat Transfer, Parts A and B, 2008
This paper presents the experimental work on the leading edge cooling performance of an integrated impingement and pin-fin cooling configuration. Experiments are conducted for seven different spatial geometries under the simulated condition of 1400 degree Celsius-class actual turbine vane leading edge with the temperature ratio of 2.1.

Micro film cooling performance

International Journal of Heat and Mass Transfer, 2009
A novel idea for micro film cooling experiment is proposed and conducted. Both fabrication of a micro film-cooled device and evaluation of its performance are presented. The film cooling device is placed in a wind tunnel system for evaluation with the blowing parameter (M) ranging from 1 to 12.5 and the film jet slot heights of 25 μm, 45 μm and 50 μm ...

Antriebstechnik: Coole Performance

DER KONSTRUKTEUR
Eine möglichst geringe Motorerwärmung ist das A und O beim Betrieb vonHochgeschwindigkeitsmotoren, die unter anderem in Turboverdichternund Schwungmassenspeichern einen wichtigen Beitrag zur Energiewendeleisten. Frequenzumrichter der Produktserie SD4x von Sieb & Meyerreduzieren umrichterbedingte Motorverluste auf ein Minimum.

Pre-Cooling and Sports Performance

Sports Medicine, 2012
Pre-cooling is used by many athletes for the purpose of reducing body temperature prior to exercise and, consequently, decreasing heat stress and improving performance. Although there are a considerable number of studies showing beneficial effects of pre-cooling, definite conclusions on the effectiveness of pre-cooling on performance cannot yet be ...

Cooling System Performance Evaluation

SAE Technical Paper Series, 1998
<div class="htmlview paragraph">With the ever increasing demand on automotive manufactures to reduce lead times, improve performance, add air conditioning, meet noise and pollution legislation the need to evaluate and improve cooling system performance at the design stage is becoming increasingly important.

Cooling Water Inhibitor Performance

Corrosion, 1960
Corrosion inhibitors in open recirculating cooling water systems require rapid and complete film formation for maximum effectiveness. The protective film is established on clean surfaces by initial treatment with inhibitor at high dosage levels. Protection then can be maintained by continuous treatment at substantially lower levels.

Performance of a Conduction Cooling Module

Journal of Electronic Packaging, 1990
A piston-type conduction cooling module for PCB-mounted IC’s has been developed and tested. Analysis of performance has been made using a finite difference scheme for the conduction piston. The effect of direct contact area between the piston and the IC as well as the effect of thermal conduction grease between them have been investigated.

Performance Study of Cooling Pads

Advanced Materials Research, 2013
The efficiency of an evaporative cooler on different cooling pads have been studied. Two type of cooling pads made of a curtain fabric and a raw cotton fabric were comparatively studied. The effect of blower speeds at 725, 1015 and 1450 RPM and water flow rate of 26.9 liters per minute were investigated.

COOL Substrate for Power and Performance

Pan Pacific Symposium, 2015
ABSTRACT Recent demands in system integration and high data transmission are challenging single chip and multi-chip packaging technologies with extremely tight pad pitch and large die size. As high I/O and fine pitch devices are increasingly being introduced, there is a critical need for a packaging substrate having ultra-fine line ...
