Thermal contact resistance between two adjacent materials is one of the major concerns in a large variety practical situations heat transfer. The presence this yields temperature jump across interface. Due to discontinuity, numerical modelling thermal runs into difficulties. In work, we propose simple and efficient model account for at immersed interfaces multi-material present based on diffuse...

A volume-penalizing immersed boundary method is presented for the simulation of laminar incompressible flow inside geometrically complex blood vessels in the human brain. We concentrate on cerebral aneurysms and compute flow in curved brain vessels with and without spherical aneurysm cavities attached. We approximate blood as an incompressible Newtonian fluid and simulate the flow with the use ...

A fixed-mesh algorithm is proposed for simulating flow–structure interactions such as those occurring in biological systems, in which both the fluid and solid are incompressible and the solid deformations are large. Several of the well-known difficulties in simulating such flow–structure interactions are avoided by formulating a single set of equations of motion on a fixed Eulerian mesh. The so...
