Thermal, structural, optical, dielectric and barocaloric properties at ferroelastic phase transition in trigonal (NH4)(2)SnF6: A new look at the old compound
Structural phase transition P-3m1 <-> P-1 of the first order and nonferroelectric nature was found in (NH4)(2)SnF6 at about 110 K in the process of thermal, optical, dielectric and X-ray studies. Order-disorder transformation ...
Barocaloric effect in ferroelastic fluorides and oxyfluorides
Using the data about the temperature - pressure phase diagram and the phase transition entropy at ambient and high pressure, intensive and extensive barocaloric effects were analyzed in the region of single and successive ...
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 ...
