Mathematical analysis of a discrete fracture model coupling Darcy flow in the matrix with Darcy-Forchheimer flow in the fracture [PDF]

open access: yesarXiv.org, 2014
We consider a model for flow in a porous medium with a fracture in which the flow in the fracture is governed by the DarcyForchheimer law while that in the surrounding matrix is governed by Darcy's law.

Computer simulation based analysis of transient two-phase thermal evolutions during multiprobe cryosurgery of hepatic tissues embedded without or with blood vessels

open access: yesInternational Journal of Thermofluids
Cryosurgery is demarcated as cell annihilation by freezing temperature yielded through a cryogenic probe. Thermal distributions nearby the adjacent blood vessels can impede the iceball evolution and surgery success.

Electric controlling of surface metal-insulator transition in the doped BaTiO3 film

open access: yesAIP Advances, 2017
Based on first-principles calculations, the BaTiO3(BTO) film with local La-doping is studied. For a selected concentration and position of doping, the surface metal-insulator transition occurs under the applied electric field, and the domain appears near

Soret and dufour impacts on radiative power-law fluid flow via continuously stretchable surface with varying viscosity and thermal conductivity

open access: yesScientific Reports
The intricate dynamics of mixed convective thermic and species transport in a power-law flowing fluid through a continuously stretched surface are investigated. The uniqueness of this study lies in the consideration of fluid variable thermic conductivity
