An embedded-boundary formulation for large-eddy simulation of turbulent flows interacting with moving boundaries
Title of dissertation: AN EMBEDDED-BOUNDARY FORMULATION FOR LARGE-EDDY SIMULATION OF TURBULENT FLOWS INTERACTING WITH MOVING BOUNDARIES Jianming Yang, Doctor of Philosophy, 2005 Directed by: Assistant Professor Elias Balaras Department of Mechanical Engineering A non-boundary-conforming formulation for simulating transitional and turbulent flows with complex geometries and dynamically moving bo...
متن کاملOptimal control of katabatic flows within canopies
What slope angle favours the development of katabatic flow is still an open question. Some studies have clarified that katabatic winds are stronger on steep slopes, while others have demonstrated that katabatic winds are stronger on gentle slopes. Here, we explore the control mechanisms of katabatic flow using a simplified theoretical model in an attempt to clarify the causes of the paradoxical...
متن کاملControl of Turbulent Flows
It is useful for many industrial applications to be able to control turbulence in uid ows, either to reduce it or, in some cases, to increase it. Active or passive control procedures are of interest. The problems that we face here are considerable and encompass those related to the control of complex nonlinear systems and those related to the direct numerical simulation of turbulent ows. Our ai...
متن کاملTurbulent Flows: General Properties
Turbulence is ubiquitous in natural fluids: atmosphere, ocean, lakes, rivers, Earth’s interior, planetary atmospheres and their convective interiors, stars, and space gases (neutral and ionized). From a mathematical perspective, its essential behaviors arise because the equations of fluid dynamics are a nonlinear partial differential equation (PDE) system. From an accompanying physical perspect...

Turbulence is ubiquitous in natural fluids: atmosphere, ocean, lakes, rivers, Earth’s interior, planetary atmospheres and convective interiors, stars, space gases (neutral and ionized), and perhaps even galaxies. From a mathematical perspective, its essential behaviors arise because the governing equations of fluid dynamics are a nonlinear partial differential equation (PDE) system, the Navier-...
