develop a thermal conductivity model suitable for process simulation using the same inputs as the EF viscosity model. The updated EF and GW viscosity models and the EF thermal conductvity model are applicable to crude oils over a wide range of API gravities, temperatures and pressures.
Table A6. Thermal conductivity and thermal expansion ..... 18 Data for engineering materials This booklet lists the names and typical applications common engineering materials, together with data for their properties.
We describe models for the viscosity, thermal conductivity, and surface tension for selected fluids implemented in version 10.0 of the NIST computer program, NIST Standard Reference Database 23, also known as NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP).
Table 1 shows the required thermophysical properties that must be available for input before reliable numerical simulations of a cast-ing process can be performed, as well as their influence in the prediction of defects. Current commercial software requires that the thermal conductivity, specific heat capacity, latent heat,
Accurate thermophysical properties are available for several fluids. These data include the following: Density. C p. Enthalpy. Internal energy. Viscosity. Joule-Thomson coefficient. Specific volume.
