2. Fluid Dynamics in Stirred Vessels - Experiments and simulations of single-phase and liquid-liquid systems
Abstract : This thesis applies experimental measurement techniques and computational fluid dynamics to evaluate turbulent mixing of liquid-liquid systems in stirred vessels. Also studies of macro-instabilities in a single-phase system and how they affect flow and thus mixing are conducted. READ MORE

5. Applicability of thermal energy storage in future district heating system - Design methodologies and performance evaluations
Abstract : District heating (DH) enables efficient and economical utilization of energy resources to satisfy the heat and hot water demands in buildings and is, thereby, well-established in Northern European countries. To achieve the future renewable energy system, the current DH systems are proved to undergo transitions towards the future DH systems, with major characteristics including renewable-based heat sources, low temperature networks, lower heating demands and smart controls.
