Optimization of operating conditions in the steam turbine blade cascade using the black-box method
Propulsion and Power Research, 2023 Water droplets cause corrosion and erosion, condensation loss, and thermal efficiency reduction in low-pressure steam turbines. In this study, multi-objective optimization was carried out using the black-box method through the automatic linking of a ...

Experimental Study on Critical Flow of Supercritical CO2 at Steady State and Model Verification
Yuanzineng kexue jishu, 2022 When the loss of coolant accident happens in a reactor, because of the high temperature and high pressure in the reactor and the low external pressure, the critical flow may occur at the break due to sharp depressurization and vaporization.

Numerical Simulation of Nozzle Flow Field with Secondary Injection Thrust Vector Control
MATEC Web of Conferences, 2018 Numerical simulations are performed to characterize the secondary injection thrust vector control. For this objective the following measurements were taken: considering the flow to be compressible and turbulent using Realizable k-ε turbulence model ...

The secular stagnation of productivity growth
, 2022 The concern that an economy could experience persistent stagnation, caused by a structural weakness of aggregate demand, goes back to Alvin Hansen's thesis of “secular stagnation.” Hansen's thesis has been revived in recent times, when it became clear ...

Research on flow field characteristic of close-coupled gas atomizing nozzles
Fenmo yejin jishuThe atomization nozzle is the core component for the metal powder preparation by close-coupled gas atomization method. The pressure at the tip of the melt delivery tube and the stagnation point is very important for the smooth outflow of the molten metal
