On Boiling of Crude Oil under Elevated Pressure
Anastasiya V. Pimenova, Denis S. Goldobin
We construct a thermodynamic model for theoretical calculation of the boiling process of multicomponent mixtures of hydrocarbons (e.g., crude oil). The model governs kinetics of th…
Formation of bubbly horizon in liquid-saturated porous medium by surface temperature oscillation
Denis S. Goldobin, Pavel V. Krauzin
We study non-isothermal diffusion transport of a weakly-soluble substance in a liquid-saturated porous medium being in contact with the reservoir of this substance. The surface tem…
Coherence of Noisy Oscillators with Delayed Feedback Inducing Multistability
Anastasiya V. Pimenova, Denis S. Goldobin
For self-sustained oscillators subject to noise the coherence, understood as a constancy of the instantaneous oscillation frequency, is one of the primary characteristics. The dela…
Noise-Produced Patterns in Images Constructed from Magnetic Flux Leakage Data
Anastasiya V. Pimenova, Denis S. Goldobin, Jeremy Levesley +2
Magnetic flux leakage measurements help identify the position, size and shape of corrosion-related defects in steel casings used to protect boreholes drilled into oil and gas reser…
Magnetic Flux Leakage Method: Large-Scale Approximation
Anastasiya V. Pimenova, Denis S. Goldobin, Jeremy Levesley +3
We consider the application of the magnetic flux leakage (MFL) method to the detection of defects in ferromagnetic (steel) tubulars. The problem setup corresponds to the cases wher…
Collision of viscoelastic bodies: Rigorous derivation of dissipative force
Denis S. Goldobin, Eugeniy A. Susloparov, Anastasiya V. Pimenova +1
We report a new theory of dissipative forces acting between colliding viscoelastic bodies. The impact velocity is assumed not to be large, to avoid plastic deformations and fragmen…
