Abstract :

Numerical methods for interface simulation and surface tension modeling have been investigated with the focus on surface tension dominant free surface and interfacial flows. The Navier-Stokes equations are solved using a finite-volume formulation with a two-step projection method on a fixed staggered grid. The interface between the liquid and gas phase is tracked by a coupled level set and volume-of-fluid (CLSVOF) method which combines the strengths of the level set (LS) and the volume-of-fluid (VOF) methods and tracks the interface with higher accuracy while maintaining mass conservation. A surface tension modeling algorithm, referred to as the pressure boundary method (PBM), which preserves the jump discontinuity of pressure at the interface, is employed to model the surface tension. The CLSVOF and PBM algorithms have been applied to several practical problems, through which the robustness and versatility of the combined scheme are demonstrated.

After the technical talk above, a recruitment talk for students interested in pursuing graduate studies in the USA will also be given. A short overview of the well-established graduate programs offered by the College of Engineering at UTA will be presented.

Biography :

Dr. Tong has extensive academic and industrial research and development experience. From 1978 to 1981, he worked as an engineer at the Westinghouse Nuclear Center in Pittsburgh, PA. His academic research involves spray combustion and numerical modeling of heat transfer and fluid flow. He was a Visiting Faculty at the Aero Propulsion Lab of Wright-Patterson Air Force Base (1984), University of California at Irvine (1986), and the Combustion Research Facility of Sandia National Lab (1987). Dr. Tong is a member of ASME and various honor societies such as Sigma Xi, Tau Beta Pi and Pi Tau Sigma. He has published extensively and has been serving as a reviewer for various technical journals. In addition, Dr. Tong had served as the chairman of graduate studies in mechanical engineering at the University of Texas at Arlington (UTA) for many years and is currently the graduate advisor. Dr. Tong received his B.S. degree from the University of Hawaii in 1977. Subsequently, he received his M.Sc. and PhD degrees from the California Institute of Technology and Carnegie Mellon University, in 1978 and 1983, respectively.
