P1-approximation for radiative transfer: application to SF6 + Cu arc plasmas
(De Gruyter Open, 2014-12-01)The objective of the paper consists of a theoretical prediction of radiative heat transfer in arc plasmas of SF6 (sulphur hexafluoride) with various admixtures of copper vapours. As a mathematical tool the P1-approximation ... -
A Review of Thermal Conductivity of Epoxy Composites Filled with AIN or BN
(IEEE, 2017-08-31)new possibility to improve thermal properties and lifetime of electrical machines is adding some micro- or nano- particles to the epoxy resin and improve the heat dissipation of the machine. This will reduce the temperature ... -
Rotor Design and Optimization of Synchronous Reluctance Machine
(MM publishing s.r.o., 2015-03-11)Svět má bezedný apetit po elektrické energii. Většina této energie je použivána pro napájení elektrických strojů. Díky tomu elektrické stroje reprezentují velký potenciál pro energetické úspory. Synchronní reluktanční motor ... -
Spatio-temporal description of the cavitating flow behavior around NACA 2412 hydrofoil
(IOP Publishing, 2015-12-06)Spatio-temporal description of the cavitating flow around hydrofoil with 8 degrees incidence using proper orthogonal decomposition (POD) is presented. POD is a suitable tool, which provides information not only about the ... -
