21. Advances in Time-gated Ballistic Imaging for Studies of Atomizing Fuel Sprays
Abstract : The transportation sector of today relies heavily on fossil fuels. This is undesirable both due to the finite nature of the fossil resources and to the effects of global warming. Therefore, there is a need to find alternative fuels and simultaneously develop combustion engines with higher efficiencies. READ MORE

22. Large Eddy Simulation of Atomizing Sprays
Abstract : Liquid-gas two-phase flows occur frequently in daily life, in nature e.g. falling rain drops or waves in the sea, and in industrial applications, e.g. READ MORE

23. Investigation of jet pulsation effects on near-nozzle mixing and entrainment
Abstract : Turbulent jet flows are very common in engineering applications. One example is that of fuel injection in internal combustion engines, which is closely related to the combustion process. Because of the widespread use, the resulting emissions of such engines have a significant impact on human health and the environment. READ MORE

24. Experimental Studies of Primary Break-up of Diesel Engine Fuel Injector Sprays
Abstract : This thesis will focus on experimental studies of primary breakup of pressure-atomized sprays. The industrial application that this thesis will address is fuel sprays in modern Diesel engines, and so the focus will be sprays emitting into relatively slow-moving, high pressure, high-temperature gases.

25. Study on Metallic Melt Coolant Interactions and Debris Bed Formation in a Water Pool
Abstract : To assess corium coolability during severe accidents of LWR, significant number of studies have been conducted previously to investigate the characteristics of debris beds formed from FCI due to fragmentation of molten corium and settlement of the fragments in a water pool. However, their focus has been placed on the oxidic component (UO2/ZrO2) of corium, while little attention has been paid to the debris bed formation due to FCI of the metallic component (Zr/Fe) of corium.
