Mathematical model of porous media dissolution coupled with two-phase flow is proposed. The model is based on the conception of dissolvable porous medium with deformable mass-variable porous skeleton. Model can be used for simulation of coupled chemo

The authors propose a mathematical model of two-phase filtration that occurs under the conditions of dissolution of a porous medium. The model can be used for joint description of complex chemical-hydrogeomechanical processes that are of frequent occ

A mathematical model of the formation of a clot (thrombosis) has been constructed in which the fibrin of the clot is considered as an elastically deformable solid phase of variable mass and the prothrombin, thrombin, fibrinogen, and fibrin monomers a

A mathematical model of the lysis of clots in blood vessels has been constructed on the basis of convectiondiffusion equations. The fibrin clot is considered as an immobile solid phase, and the plasminogen, plasmin, and plasminogen activators — as
