5Dr. KOH Yee Kan (mpekyk@nus.edu.sg)Anisotropic Heat Conduction in Carbon Nanotube FibersCarbon Nanotube Fibers could be used for novel applications, including for high-strength military vests, sporting goods and automobile applications. However, the thermal conductivity of carbon nanotube fibers is still relatively unknown, due to mainly the changes to accurately measure them. The thermal conductivity of carbon nanotube fibers is highly anisotropic, with heat resistance along the fibers much lower than heat resistance across the fibers. In this project, the student will experimentally measure the anisotropic thermal conductivity of carbon nanotube fibers, using a novel pump-probe setup in the lab. The work could lead to carbon nanotube fibers with good thermal propertiesHeat Transfer, carbon nanotube fibersStudents with backgrounds in Mechanical Engineering, Materials Science and Engineering, or Physics are welcomed.1

The phase-field formulation will be also applicable to ice modeling for Arctic conditions (unlike VOF formulation). There exist no such studies in the literature. Until now, there have been some experimental studies to understand the effects of wave-induced stresses and vortex force on a turbulent current profile. A renewed effort in this area, in close cooperation with ongoing CFD simulations, with appropriate hybrid turbulence model, will enable improved physical insight of the wave-current interactionCFD, finite elements, fluid mechanicsFluid and Solid Mechanics, Finite Elements Methods, Computational Fluid Dynamics1
