The VOF (volume of fluid) multiphase transient simulation model of the windage loss of the gear pair under oil-jet lubrication was carried out by using the dynamic mesh technology with the powerful parallel computing capabilities of the Super Cloud Computing Center.Firstly, a two-phase (oil-gas) turbulence numerical model was established in the pro
Swiss Federalism builds on the traditional and to a certain extent also themodern diversities.Since middle age the Swiss confederation has always beenenriched and challenged by economic, religious, cultural and linguistic diversities.Since the foundation of Switzerland as a state of modernity in 1848the constitution has been more than 100 times mod
Due to the lack of the support from the main grid, the islanded hybrid ac/dc microgrid will more likely cause the power flow severe fluctuation and even the microgrid to be split once Serveware a serious contingency occurs.To maintain the security and stability of the system under such a condition, this paper proposes a new static security risk ass
