Modeling of Local Hematocrit for Blood Flow in Stenotic Coronary Vessels

Fluids, 2023
This mainly theoretical work is devoted to the study of the contribution of the cell-free layer (CFL) near the vessel wall to hemodynamics in a large coronary artery with stenosis to assess the relevance of CFL modeling to the needs of interventional ...

Physical modelling of tundish slag entrainment under various technological conditions [PDF]

, 2017
This paper deals with the issue of physical modelling of vortexes creation and tundish slag entrainment over the mouth of the nozzle into the individual casting strands. Proper physical model is equivalent to the operational continuous casting machine No.

Co3O4 surface studies and adsorption of Li2O2 nanocluster [PDF]

MATEC Web of Conferences
Lithium-air batteries are one of the most promising energy storages, characterized by their high energy density and substantial specific capacity. However, their performance is affected by high charging over potential and poor cycling stability.

The theory of direct magnetoelectric effect in the bilayer system of ferromagnetic–piezoelectric [PDF]

Journal of Advanced Dielectrics, 2016
The theory of direct magnetoelectric (ME) effect in a bilayer of ferromagnetic and piezoelectric is developed taking into account nonuniform distribution of electrical field on a piezoelectric layer thickness.

Physical modelling of degassing process by blowing of inert gas [PDF]

, 2018
This paper deals with the possibilities of using physical modelling to study the degassing of metal melt during its treatment in the refining ladle. The method of inert gas blowing, so-called refining gas, presents the most common operational technology ...

Analytic and numerical realisations of a disk galaxy [PDF]

, 2010
Recent focus on the importance of cold, unshocked gas accretion in galaxy formation -- not explicitly included in semi-analytic studies -- motivates the following detailed comparison between two inherently different modelling techniques: direct ...

The Physical Conditions in Starbursts Derived from Bayesian Fitting of Mid-IR SEDS: 30 Doradus as a Template [PDF]

, 2011
To understand and interpret the observed Spectral Energy Distributions (SEDs) of starbursts, theoretical or semi-empirical SED models are necessary. Yet, while they are well-founded in theory, independent verification and calibration of these models ...
