Hybrid methods for simulating hydrodynamics and heat transfer in multiscale (1D-3D) models
The work is devoted to application of different-scale models in the simulation of hydrodynamics and heat transfer of large and/or complex systems, which can be considered as a combination of extended and "compact" elements. ...
An experimental study of dependence of hydro turbine vibration parameters on pressure pulsations in the flow path
The operation modes of the hydraulic power plant water turbine with the formation of a precessing vortex core were studied on the hydrodynamic set-up with the model of hydraulic unit. The dependence of low-frequency ...
Numerical investigation of flow structure and pressure pulsation in the Francis-99 turbine during startup
We performed numerical simulation of flow in a laboratory model of a Francis hydroturbine at startup regimes. Numerical technique for calculating of low frequency pressure pulsations in a water turbine is based on the use ...
