Heat transfer enhancement in tubes is widely applied various industrial processes. The traditional method of heat to insert radial fins expand the internal surface area and destroy flow. However, there a flue gas corridor central tube, cost expanding inner fin high. A centrally symmetrical bent extruded aluminum was developed enhance tube. An experimental platform constructed test performance f...

Abstract Tensor shape mismatch is a common source of bugs in deep learning programs. We propose new type-based approach to detect tensor mismatches. One the main features our best-effort inference. As inference problem undecidable general, we allow static type/shape be performed only manner. If cannot guarantee absence inconsistencies, dynamic checks are inserted into program. Another feature g...

In this study, the effect of microstructural characteristics on mechanical properties high-chromium white cast iron-matrix composites reinforced by in situ TiC and ex WC was investigated. To end, two different powder mixtures (Ti + Al graphite Fe) were compressed to produce green compacts that inserted into mold, before casting. The microstructure resulting base metal characterized using optica...

The use of metal foams as permanent cores in casting products is a promising strategy. It aims to improve the properties cast components by adding certain foam features (e.g., lightweight, high specific stiffness, impact energy/vibration absorption ability, and good acoustic insulation properties). eliminates steps removal, treatment, compulsory recycling for traditional temporary sand cores. H...
