1. Heat and Mass Transfer Investigations of Relevance for Food Engineering Applications
University dissertation from Mrs Gunvi Andersson, Div. Heat Transfer, Box 118, 22100 Lund, SwedenAbstract : This thesis concerns two interrelated subjects of heat and mass transfer processes. The first one concerns mainly experimental measurements, with a subsequent development of a calculation procedure, of the thermal and hydraulic performances, experimental methods and evaluation procedures applied on various plate heat exchangers (PHEs) as evaporators with the refrigerant ammonia as working medium.

3. Computational Analysis of Gas Flow and Heat Transport Phenomena in Ducts Relevant for Fuel Cells
University dissertation from Jinliang Yuan, Division of Heat TransferAbstract : The thesis concerns modeling, simulation and numerical analysis of heat and mass transport, and fluid flow in ducts of both solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). The unique fuel cell boundary conditions (thermal, mass) for the flow ducts in fuel cells are identified and applied. READ MORE

4. On CFD-Analysis of Heat Transfer of a Heavy-Duty Diesel Engine
University dissertation from Jinliang Yuan, Division of Heat TransferAbstract : In this work, a heavy-duty diesel engine was studied by employing CFD simulations on a closed volume engine segment. These simulations were used to evaluate both the effects from certain parameters on the wall heat transfer, and to examine how reduction of heat transfer would effect the engine performance and emission levels.

5. Computational Analysis and Modeling Techniques for Monolithic Membrane Reactors Related to CO2 Free Power Processes
University dissertation from Heat TransferAbstract : Funded by European Community and Swiss government research project AZEP (Advanced Zero Emission Power Plant), the project was carried out at the Department of Energy Sciences at Lund Faculty of Engineering (LTH). The project addressed the development of a specific, zero emissions, gas turbine-based, power generation process to reduce local and global emissions in a cost-effective way. READ MORE
