A Heat Transfer Model Combining Differential and Integral Formulations for Thermal Analysis of Reciprocating Compressors

, 2012
Heat transfer in hermetic compressors is a complex phenomenon strongly affected by fluid flow inside and outside the compression chamber and by the efficiency of both the electrical motor and the crankshaft mechanism.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Heat Transfer Performance of Axially Grooved Heat Pipes

Heat Transfer Performance of Axially Grooved Heat Pipes
This paper describes experiments and analysis of the heat transport capability of axially grooved heat pipes. The heat pipes were made of aluminum axially grooved extruded pipes and the working fluid was R11. The effects of fluid inventory and inclination angle on the capillary pumping limit were investigated.

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
