The investigation of boiling crisis of nanofluids
Saturated boiling of nanofluids on a cylindrical heater with different diameters is experimentally studied. Studied nanofluids were prepared using distilled water and different metal oxides nanoparticles. The volume ...
Experimental investigation of pool boiling of water-based AL2O3 nanofluid on a copper cylinder
Saturated boiling of nanofluid on a copper cylinder is experimentally studied. The studied nanofluid were prepared using distilled water and Al2O3 nanoparticles. The volume concentration of the nanoparticles was equal 3 ...
Experimental study of the effect of air injection on the pressure pulsations in the hydro turbine flow path under different operating conditions
The paper presents an experimental study of oscillatory response in the Francis turbine of hydraulic unit. The experiment was performed on large-scale hydrodynamic test-bench with impeller diameter of 0.3 m. The effect of ...
The study of the influence of stabilizing devices on the pressure pulsations at the free discharge of water through the turbine
The free discharge through the turbine is applied in the course of construction of hydro power plant or in case of excessive water inflow during floods or emergency situations. The experimental and numerical investigation ...
An experimental study of the influence of pressure pulsations in the water turbine flow path on vibration parameters of the hydraulic unit
The paper presents an experimental study of the relationship between the vibration of the water turbine unit and the pressure pulsations in the flow path. It is shown that the air injection into the flow path leads to a ...
Density effect on the mixing efficiency and flow modes in T-shaped micromixers
Flow patterns and mixing of liquids with different densities in T-shaped micromixers are numerically investigated at Reynolds number range from 1 to 250. The density ratio of the mixing media varies from 1 to 2; its effect ...
