Heat Transfer Characteristics of High Crossflow Impingement Channels: Effect of Number of Holes

Peter Ott, Alexandros Terzis, Santiago Llucià

In modern turbine airfoils, narrow impingement cooling channels can be formed in a double-wall configuration. In these wall-integrated cooling cavities, the generated crossflow is one of the most important design factors, and hence, the number of impingeme ...

Comprehensive Consideration on AMR Configuration for Magnetocaloric Heat Pump

Didier Albert Simon Vuarnoz

This paper discusses the system performance of a magnetic heat pump with an active magnetic regenerator. The heat-transfer coefficient and pressure drop in the AMR are performed analytically. Measurements on the experimental magnetic heat pump test device ...

GreenCool: An Energy-Efficient Liquid Cooling Design Technique for 3-D MPSoCs Via Channel Width Modulation

David Atienza Alonso, Arvind Raj Mahankali Sridhar, Ayse Kivilcim Coskun, Jie Meng

Liquid cooling using interlayer microchannels has appeared as a viable and scalable packaging technology for 3-D multiprocessor system-on-chips (MPSoCs). Microchannel-based liquid cooling, however, can substantially increase the on-chip thermal gradients, ...

Integrated analysis of quench propagation in a system of magnetically coupled superconducting coils

Luca Bottura

We demonstrate in this paper how to use direct modeling of heat transfer and circuital equations based on "packaged" simulation tools to produce a model suitable for the study of quench propagation in a system of magnetically coupled solenoids protected wi ...
