Porous materials can be found in numerous areas of life (e. g., applied science, material science), however, the simulation fluid flow and transport phenomena through porous media is a significant challenge nowadays. Numerical simulations help to analyze understand physical processes different structure, as well determine certain parameters that are difficult or impossible measure directly only...

This paper investigates the effect of metallic sheaths on losses and temperature of medium voltage power cables. Two grounding methods of sheaths, including both ends bonding and single point bonding that causes different situations on cable ampacity, are considered. Electrical losses of cables that are main sources of heat are calculated in both conductor and metallic sheath of the cables. She...

Due to economic and ecological trends, materials used in the automotive industry are expected be lightweight. One of most important advantages lightweight is a reduction raw material consumption, which results lower production costs. In aviation industry, one features its density. Obtaining with density allows reduce total weight vehicle, causes improved performance fuel consumption. key soluti...
