Abstract: A multistage vaneless counterrotating turbine (MVCRT) eliminates vanes between rotors, which reduces the weight and size of the turbine and avoids viscous losses associated with vanes pronouncedly. An aircraft engine ...

Abstract: A four-dimensional variational data assimilation system consisting of a three-dimensional time-dependent cloud model with both liquid and ice phase microphysics parameterization was used to assimilate radar data into a ...

Abstract: To investigate the lubrication mechanism of carbon nanospheres and compare their tribological performance with carbon powder, this study presented a comprehensive analysis of their potential as lubricant additives through ...

Abstract: Two gaseous fire-extinguishing agents, N2 and C3H2F6, were used to suppress open-flame coal combustion, and their inhibitory effects as well as the corresponding mechanisms were probed by simulations and confined-space ...
