Two phase magnetic material modelling using two dimensional extended Preisach model
Journal of Electrical Engineering, 2018 Abstract Extended Preisach model parameters can be strongly related to microstructural properties of material. It can also include real physical magnetization mechanisms such as domain wall motion and domain rotation. This paper shows that Preisach model is able to anticipate different phases in material structure.

Two-dimensional calculations of stratified turbulent flow in a pipe
Қарағанды университетінің хабаршысы. Математика сериясы, 2019 In this paper, we consider the stratified turbulent flow of a two - phase medium in inclined pipes. Based on the new turbulence model [1], a program code for calculating two - dimensional flows for the study of two - phase stratified flows in pipes was ...

Chiral Schwinger model with Faddeevian anomaly and its BRST quantization
European Physical Journal C: Particles and Fields, 2020 We consider chiral Schwinger model with Faddeevian anomaly, and carry out the quantization of both the gauge-invariant and non-invariant version of this model has been.

The Longitudinal Flow of Oil and Petroleum Products in the Channels and Pipes: Part II
Chemical Engineering Transactions, 2019 A model associated fluid flow and heat transfer of longitudinal flows of oil in pipes and channels are considered. The model is an extended version of the Bingham flow on the case of flow with one or two solid cores. The fluid part is a two-phase medium,
