A compressible viscous three-phase model for porous media flow based on the theory of mixtures
Qiao, Yangyang; Evje, Steinar (Peer reviewed; Journal article, 2020)In this paper we focus on a general model to describe compressible and immiscible three-phase flow in porous media. The underlying idea is to replace Darcy’s law by more general momentum balance equations. In particular, ... -
Mathematical and Numerical Modelling of Lithium Battery
Bandara, Yasas (Master thesis, 2021)Application of lithium-ion batteries have increased in recent years due to their high energy density, low weight and smaller form factor. Machine learning algorithms are used in lithium-ion battery management systems due ... -
Mathematical modeling of compressible and incompressible multiphase flow based on mixture theory
Qiao, Yangyang (PhD thesis UiS;501, Doctoral thesis, 2020-11)MIXTURE THEORY has been developed based on balance laws and conservation principles which is well known in continuum mechanics, and has been widely applied to systems which can be characterized as a mixture of interacting ... -
On the numerical discretization of a tumor progression model driven by competing migration mechanisms
Qiao, Yangyang; Li, Qing; Evje, Steinar (Peer reviewed; Journal article, 2021)In this work we explore a recently proposed biphasic cell-fluid chemotaxis-Stokes model which is able to represent two competing cancer cell migration mechanisms reported from experimental studies. Both mechanisms depend ... -
Simulation of Counter-Current Spontaneous Imbibition Based on Momentum Equations with Viscous Coupling, Brinkman Terms and Compressible Fluids
Tantciura, Sergei; Qiao, Yangyang; Andersen, Pål Ø. (Peer reviewed; Journal article, 2021)A numerical model is investigated representing counter-current spontaneous imbibition of water to displace oil or gas from a core plug. The model is based on mass and momentum conservation equations in the framework of the ...
