Thermal conductivity of supercooled water.
The heat capacity of supercooled water, measured down to -37°C, shows an anomalous increase as temperature decreases. The thermal diffusivity, i.e., the ratio of the thermal conductivity and the heat capacity per unit volume, shows a decrease. These anomalies may be associated with a hypothesized liquid-liquid critical point in supercooled water below the line of homogeneous nucleation. However...
متن کاملThe Study of Thermal Conductivity Silver/Water Nanofluid
In present study, the thermal conductivity of silver/water nanofluid was investigated experimentally. Four different volume concentrations of nanofluids (2, 3, 5 and 10%) were prepared by dispersing silver nanoparticles in water. The properties of nanofluids were measured by varying the temperature from 20ºC to 100ºC and also, different sizes of nanoparticles dispersed in water (20-30, 50-60 an...
متن کاملThermal Conductivity of Cu and Al-Water Nanofluids
Nanofluids are suspensions of nanoparticles in the base fluids, a new challenge for thermal sciences provided by nanotechnology. In this paper, the tested fluids are prepared by dispersing the Al and Cu into water at three different concentrations such as 500, 1000 and 2000 ppm. Thermal conductivities of these fluids are measured experimentally by thermal property analyzer i.e. KD2 Pro by using...
متن کاملThermal conductivity of ordered molecular water.
The authors use molecular dynamics simulation to investigate the thermal transport characteristics of water with various degree of orientational and translational orders induced by the application of an electric field. The authors observe that the orientational ordering of the water dipole moments has a minor effect on the thermal conductivity. However, electric-field-induced crystallization an...
متن کاملThermal conductivity minimum: a new water anomaly.
We investigate the thermal conductivity of liquid water using computer simulations of the TIP5P model of water. Our simulations show that, in addition to the maximum at high temperatures at constant pressure that it exhibits in experiments, the thermal conductivity also displays a minimum at low temperatures. We find that the temperature of minimum thermal conductivity in supercooled liquid wat...
