Abstract Most of common thermal jackets for gun tubes are composite types, which have large mass and complex structures. With the development material technology, a single-layer jacket using new materials with low conductivity has good protection effects on tubes. The design requires consideration thickness, air gap, properties structural strength. In order to study factors that affect performa...

Abstract We present a study of smart growth in layered cylindrical structures. start from the characterization compatible field an anisotropic growing tube with aim to show small perturbation that may produce controlled deprivation compatibility and localization elastic energy storage composite structure made up tubes.

Metals are common construction materials for heat exchangers. However, metals may suffer from failure due to corrosion, especially in harsh environments. Innovative thermally conductive polymer composite tubes based on polypropylene or polyphenylene sulfide filled with graphite have been developed. Crystallization fouling metal surfaces has extensively studied. data very limited. In the current...

The properties of composite black holes in the background of electric or magnetic flux tubes are analyzed, both when the black holes remain in static equilibrium and when they accelerate under a net external force. To this effect, we present a number of exact solutions (generalizing the Melvin, C and Ernst solutions) describing these configurations in a theory that admits composite black holes ...
