Due to the homogeneous and continuous nature of fractured SiC fibers, there has been a lack effective methods for repairing macroscopic crack damage in SiCf/SiC composites, making it impossible achieve in-situ regeneration broken fibers. This study utilized COMSOL simulation software establish process system model preparation SiCnw through HFCVD. Based on gas-phase components during pyrolysis MTS, chemical vapor deposition reaction mechanism was explored. The coupled heat transfer module...
To access the enhancement effect of topology optimization and porous foam structure, numerical studies were conducted to investigate heat conduction (by metal foam, graphite topologically optimized fins, combinations fins) phase change material (PCM (n-octadecane)) based tubular thermal energy storage unit for spacecraft. The results showed that performed better than fins a combination which conductive material, mass, volume fraction PCM same. Graphite (140 W/(m·K)) had best transfer...
The utilization of Erythritol/xylitol eutectic material for low-temperature thermal energy storage and management holds great promise.

This research paper introduces novel technique that combines gas injection agitation seeding address this issue. study aims investigate the impact tube diameter, environment, duration on characteristics material. Experimental analysis reveals that, under...
The latent heat storage unit (LHSU) using phase change material (PCM) is a quite attractive passive thermal management technique. Graphite foam-PCMs composite are very useful especially in electronics cooling system for power applications due to their high energy weight ratio and response rate. A numerical study proposed investigate predict the behavior performance of LHSU foam-PCMs. simulation program based on finite volume approach was developed evaluate LHSU, enthalpy porosity method used...
Shape memory alloy (SMA) is a promising material which has widely been applied in aerospace industry. Its unique nature of the high stress output rate and low power requirement agrees need energy saving aircraft de-icing. Among few designs SMA de-icer, Gerardi's project for rotating blade more fit to de-icer aircrafts. However, it not clear that if capable de-icing non-rotating components or not. In this study, design were presented. Characteristics factors influence on confirmed by...
