• Aware Load Direction for Servers: A Feasibility Study

  In this paper, scientists from State University of NY, Binghampton, who are also a part of the National Science Foundation ES2 Lab address the problem of improving the energy efficiency of servers that provide web-based services, including services provided through clouds. They propose an automated technique for allocating workload to servers to operate the fewest number of servers that are... details>>

• Models for Battery Reliability and Lifetime - White Paper from National Renewable Energy Lab

  Models describing battery degradation physics are needed to more accurately understand how battery usage and next generation battery designs can be optimized for performance and lifetime. Such lifetime models may also reduce the cost of battery aging experiments and shorten the time required to validate battery lifetime. Models for chemical degradation and mechanical stress are reviewed.... details>>

• Heat Transfer Enhancement by Finned Heat Sinks with Micro-structured Roughness

  Researchers at the Polytechnic Univeristy of Turin Italy investigated the benefits of micro-structured roughness on heat transfer performance of heat sinks, cooled by forced air. Heat sinks in aluminum alloy by direct metal laser sintering (DMLS) manufacturing technique were fabricated; values of the average surface roughness from 1 to 25 microns (standard milling leads to roughness around 1... details>>

• SANYO DENKI AMERICA, INC. Fundamentals of Brushless DC Axial Cooling Fans

  Brushless DC (BLDC) fans have become the most popular mode of electronics cooling in recent years. They impart kinetic energy to a localized air mass and increase the fluid velocity, which in turns increases the convectional coefficient, h, and increases the amount of heat removed. The fluid velocity is directly proportional to h through the Reynolds and Nusselt number equations. The... details>>

• A Two-Phase Pressure Drop Model Incorporating Local Water Balance and Reactant Consumption in PEM Fuel Cell Gas Channels

  A two-phase 1-D pressure drop modeling scheme that incorporates the effect of local channel saturation on flow regime is introduced. The model provides a basis for extending two-phase pressure drop correlations from fundamental studies to more complex conditions within PEMFC reactant channels. The need for additional studies beyond the fundamental level is highlighted and key factors that... details>>

• State-of-the-art research study for green cloud computing

  Although cloud computing has rapidly emerged as a widely accepted computing paradigm, the research on cloud computing is still at an early stage. Cloud computing suffers from different challenging issues related to security, software frameworks, quality of service, standardization, and power consumption. Efficient energy management is one of the most challenging research issues. The core services... details>>

• Boiling Heat Transfer in Battery Electric Vehicles

  In this paper the feedback stabilisation of a boiling-based cooling scheme is discussed. Application of such cooling schemes in practical setups is greatly limited by the formation of a thermally insulating vapour film on the to-be-cooled device, called burn-out. In this study a first step is made, to check the viability of such cooling systems, already used in high performance electronics,... details>>
