The viscosity and thermal conductivity of ethane in the limit of zero density

New independent representations of the viscosity and thermal conductivity of ethane in the limit of zero density. For viscosity, the correlation is over the temperature range of 200 to 1000 K, with the highest uncertainty being 2.5% . The correlation for thermal conductivity covers from 225 to 725 K with a highest uncertainty of 3%....

Experimental Data for the Viscosity and Thermal Conductivity of Water and Steam

All reliable experimental data available relating to the viscosity and thermal conductance of water has been collected and turned into the current temperature scale and a set of units. There are four groups of data collected; liquid at ambient pressure, the rest of the liquid phase, the vapor phase, and the super-critical region. For each data point collected, a density was calculated theoretically. Viscosity was measured in the range of ...

Thermal conductivity of four polyatomic gases

The transient hot wire method was used to measure the thermal conductivity of the following polyatomic gases: hydrogen, nitrogen, carbon monoxide and methane. The measurements occurred in the range from 0.8-10 MPa, at 35 degrees Celsius, and have an estimated uncertainty of ±0.2%....

The viscosity and thermal conductivity of normal hydrogen in the limit of zero density

With a basis upon the semi-classical kinetic theory of polyatomic gases and critically examined data, a new representation of the viscosity and thermal conductivity coefficients of normal hydrogen is created in the limit of zero density as a function of temperature. Measurements are made with the transient hot wire method, among others, and are taken between 20 and 2200 Kelvin. The highest uncertainties are 2%, ...

Potential applications of nanofluids for heat transfer

Multiple studies claiming the usefulness of nanofluids for the enhancement of heat transport have been proven ill-founded. Although they have significantly raised thermal conductivities, there is an inerrant increase in viscosity when adding nanoparticles to a liquid. This paper explores areas of research that analyze nanofluid properties that could potiential indicate future applications. A promising direction is using particles that can change ...
