Experimental observation of the precessing-vortex-core reconnection phenomenon in a combined-flow turbine
Some results of experimental studies of the vortex-core reconnection phenomenon in the flowthrough duct of a combined-flow turbine were presented. The studies were performed on a medium-scale hydrodynamic test bench, the ...
Rheological behavior of water and ethylene glycol based nanofluids containing oxide nanoparticles
The paper presents the results of experimental study of rheological behavior of nanofluids based from consideration of several tens of nanofluids based on water, ethylene glycol and engine oil, containing particles of ...
Experimental-calculated study of the forced convection magnetic nanofluids
Experimental-calculated study of the magnetic nanofluids forced convection in a constant magnetic field was carried out. Dependence study of the magnetic nanofluid heat transfer coefficient on the effect of a constant ...
Numerical investigation of hydroacoustic pressure pulsations due to rotor-stator interaction in the Francis-99 turbine
The paper deals with the numerical simulation of the flow in the Francis-99 hydraulic turbine at three different problem formulations, namely, the application of the method of rotating coordinate system, sliding mesh model, ...
Experimental study of the swirling flow effect on the efficiency of the local ventilation system
The paper presents the results of an experimental study of the local ventilation system. It is shown that the use of radially swirled counter-flow jet leads to significant increase in the efficiency of gas removing. This ...
