Viscosity and thermal conductivity of heavy oils in the region of high temperatures and pressures

The coefficients of dynamic viscosity and thermal conductivity of heavy high-viscosity oils (HVO) are experimentally and theoretically investigated at high temperatures and pressures. Methods are suggested for the calculation of dynamic viscosity and thermal conductivity of HVO in a wide range of parameters of state. The methods are developed on the basis of experimental data using elements of the theories of information and thermodynamic similarity of the properties of substances.
