Uncertainty analysis is the process of estimating the uncertainty in a result calculated from measurements with known uncertainties. Uncertainty analysis uses the equations by which the result was calculated to estimate the effects of measurement uncertainties on the value of the result. Uncertainty analysis is used in the planning stages of an experiment to judge the … [Read more...]
Heat pipe fundamentals
The use of heat pipes in thermal management is increasing rapidly as power densities in electronics continue to rise. Heat pipes are attractive because they can typically carry 100 or more times as much heat as an equivalent piece of solid copper. The basic principle of heat pipe operation is very simple. A small amount of working fluid, typically water, is sealed inside a … [Read more...]
Graphite fiber reinforced al and cu alloys for thermal management applications
Technological advances in the electronics industry have revolutionized the way the world communicates and conducts business. Today's electronic products, from cellular phones to sophisticated imaging satellites, demand lightweight, low-cost materials that provide more functionality in less volume. To meet these challenges, electronic systems must dump large amounts of waste … [Read more...]
Acoustic noise emission and communication systems in the next century
Acoustic noise emission is one of several physical design issues addressed during the design of telecommunications and information technology equipment. In most systems, noise is a by-product of the air-movers used for system cooling. The amount of heat dissipated in electronic systems cooled by forced convection is directly proportional to volumetric flow rate. The flow rate, … [Read more...]
Beyond the arrow plot – New methods for flow visualization
Within the realm of CFD-based flow analysis, the presentation of data is a vital issue. Researchers and developers need to gain insight, and non-technical managers and commercial staff have a critical need to understand the true ramifications of the data. Unfortunately, current methods for visualizing flow have limitations that make it difficult to interpret vast quantities of … [Read more...]
