The article analyzes the modern theory and practice of pipeline transport bituminous oil together with low-viscosity solvent. In addition, a detailed analysis rheological models non-Newtonian fluids is carried out, which establishes number assumptions on rheology model selection algorithm currently in use (limited models, variability coefficient assignment, etc.). Ways their elimination are pro...

Increasing interests have been paid to nanofluids because of the intriguing heat transfer enhancement performances presented by this kind of promising heat transfer media. We produced a series of nanofluids and measured their thermal conductivities. In this article, we discussed the measurements and the enhancements of the thermal conductivity of a variety of nanofluids. The base fluids used in...

A new approach to calculate the axially symmetric binary gas flow is proposed Dalton’s law for partial pressures contributed by each species of a binary gas mixture (argon and helium) is incorporated into numerical simulation of rarefied axially symmetric flow inside a rotating cylinder using the time relaxed Monte-Carlo (TRMC) scheme and the direct simulation Monte-Carlo (DSMC) method. The res...

A complete thermodynamical analysis for a binary mixture of viscous Korteweg fluids with two velocities and temperatures is developed. The constitutive functions are allowed to depend on the diffusion velocity specific internal energies both constituents, together their first gradients, symmetric part gradient barycentric as well mass density concentration one second gradients. Compatibility en...

This paper concentrates on the propagation of waves in a layer of binary mixture of elastic solids subjected to stress free boundaries. Secular equations for the layer corresponding to symmetric and antisymmetric wave modes are derived in completely separate terms. The amplitudes of displacement components and specific loss for both symmetric and antisymmetric modes are obtained. The effect of ...

In the course of the last thirty years, light scattering techniques have been used with increasing effort and attention for the measurement of the thermophysical properties of pure fluids and fluid mixtures. Here, an introduction is given to dynamic light scattering (DLS) as a valuable tool for the measurement of diffusion processes. First, the basic principles of the method and its experimenta...
