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 ...
On laminar-turbulent transition in nanofluid flows
The paper presents experimental data on the laminar-turbulent transition in the nanofluid flow in the pipe. The transition in the flows of such fluids is shown to have lower Reynolds numbers than in the base fluid. The ...
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 ...
