Studying laminar flows of power-law fluids in the annular channel with eccentricity
The paper deals with numerical and experimental investigation of non-Newtonian flow of modeling drilling fluids in the annular channel. The Reynolds number was ranged from 100 to 1500. The parameters of the power-law model ...
Investigation of the additive effect of nanoparticles on the hydrodynamic characteristics of drilling fluids
Investigations of the rheological properties of drilling fluids based on nanoparticles are carried out. The dependences of the effective viscosity and rheological parameters of fluids on the concentration, size and material ...
Structure and magnetic properties of titanium nickelide nanoparticles synthesized by pulsed laser ablation method
We have successfully synthesized magnetic titanium nickelide nanoparticles with equiatomic composition by pulsed laser ablation method. Using transmission electron microscopy and microanalysis was revealed that particles ...
Effect of liquid-phase sintering as a means of quality enhancement of pseudoalloys based on copper
The effects of liquid phase of metal binder on the microstructure and properties of self-diffusion gradient composite (Cu - Al – ZnO) were investigated. For the compositions considered, it was revealed that at ...
Change in generally accepted regularity of phase transformations of quartzite
Abstract The subject of this research is phasic transformations of quartzites that are under temperature treatment to remove moisture. This technology is used in enterprises operating melting furnaces. The studies have ...
