Numerical Simulation of Multi Physics Problems Including Fluids, Thermal, Structures, Thermal Stresses and Strains

Most real-world problems involve numerous interacting phenomena. These researchers are focused on doing problems where these phenomena and their interactions must be addressed. As an example, the problem of nanoparticle conveyance and deposition involves fluid-particle flows that experience numerous shock waves before the particles reach their target. A similar but different example occurs in the surgical tool that is used in cryosurgery. Other problems where interactions abound involve the coanda effect, which causes fluid jets to adhere to nearby surfaces rather than passing those surfaces without interaction. Still another example is the extraction of nano-size coal particles from fluid streams in order that these particles be subsequently used in slurries with water that burn with high effectiveness. This group is also interested in interactions of structures with other structures as occurs when guide wires interact with the inner surfaces of blood vessels. This is especially important when the blood vessel is highly curved, as in the aortic arch. The complexity of these problems requires the capacity of a supercomputer.
