1. Computational Free-Surface Flows Computational Techniques for Nonlinear Seepage Flow in Porous Media with Free and Moving Boundaries
Sammanfattning : Motion of a viscous fluid interface is encountered in many physical processes in engineering applications. The accurate representation and efficient numerical solution of the fluid interface are crucial problems in simulations of the physical processes in these applications. LÄS MER
2. CFD MODELLING AND EXPERIMENTS ON AERATOR FLOW IN CHUTE SPILLWAYS
Sammanfattning : A chute spillway is a typical component of large dams for discharging floods. Because of the high water head, the flow velocity in the chute is often in excess of 20 m/s. Consequently, the structure is usually prone to cavitation damages. Flow aeration is evidenced to efficiently eliminate or to mitigate the damages. LÄS MER
3. Numerical Methods for Fluid Interface Problems
Sammanfattning : This thesis concerns numerical techniques for two phase flowsimulations; the two phases are immiscible and incompressible fluids. Strategies for accurate simulations are suggested. LÄS MER
4. Numerical Simulations of Physical Discontinuities in Single and Multi-Fluid Flows for Arbitrary Mach Numbers
Sammanfattning : Physical discontinuities, such as shocks and interfaces occur commonly in fluid mechanics. The emphasis of this dissertation lies on numerical simulations of shocked aerodynamic flows and two fluid flows with sharp interfaces in which Rayleigh-Taylor instability is present. LÄS MER
