1. On-Engine Turbocharger Performance Considering Heat Transfer
Abstract : Heat transfer plays an important role in affecting an on-engine turbocharger performance. However, it is normally not taken into account for turbocharged engine simulations. READ MORE

2. Numerical predictions of heat-transfer applied to electrical machines
Abstract : In order to meet the need for increased electrification, and at the same time reduce the total demand for electric energy, behavior change and technological innovation is needed. Over the decades power density of electric motors have increased, leading to increased demands on the cooling system design and performance. READ MORE

3. Numerical Simulation of Turbulent Flows for Turbine Blade Heat Transfer Applications
Abstract : Turbine blade heat transfer is an important engineering problem characterized by complex flow fields and high turbulence levels. This thesis is focused on using a full Navier-Stokes solver with two-equation eddy-viscosity models to predict external heat-transfer in single-stage, linear, two-dimensional uncooled turbine cascades.

4. Combustion, Fluid Dynamics and Heat Transfer in Oxy-fuel and Air-Fired CFB boilers
Abstract : The studies described in this thesis develop and encode modeling tools for the design and scale-up of oxy-fuel circulating fluidized bed (CFB) boilers across a wide range of operational conditions. The modeling comprises fluid dynamics, combustion, and heat transfer and uses expressions that are proposed in this work or derived from the literature, together with experimental data obtained under both oxy-fuel-fired and air-fired conditions.

5. Heat-transfer Enhancement for Slurries from Biogas Plants− Properties, processes, and thermal systems
Abstract : Biomethane production from renewable residues with anaerobic digestion gains increasing attention as a crucial alternative to petroleum fuels. It has been vigorously developed, but the large amounts of subsidy from the government indicate that the process efficiency needs to be further improved. READ MORE
