1. Exergy Evaluation of Engine Operations : Combustion Process to Exhaust Flow
Abstract : Transitioning the transport sector to clean energy sources is crucial for mitigating greenhouse gas emissions and achieving carbon neutrality. A collaborative solution, combining both electric vehicles and combustion engines using renewable fuels, may prove more effective than competitive ones. READ MORE

2. Aerothermodynamics and exergy analysis in turbocharger radial turbine
Abstract : Coupling of turbomachine to reciprocating automotive engine in turbocharging leads to complex fluid flow and thermal characteristics in the turbine. Some undesirable characteristics include heat transfer, flow pulsation and secondary flow due to the complex geometry of the upstream exhaust manifold. READ MORE

3. Efficiency and Mixing Analysis of EGR-Systems for Diesel Engines
Abstract : The reduction of fuel consumption and the reduction of toxic emissions are the main goals of research and development in the area of internal combustion engines. The use of exhaust gas recirculation (EGR) to come further in that direction is today an established method for diesel engines. READ MORE

4. A novel solar-driven system for two-step conversion of CO2 with ceria-based catalysts
Abstract : Global warming is an unequivocal fact proved by the persistent rise of the average temperature of the earth. IPCC reported that scientists were more than 90 % certain that most of the global warming was caused by increasing concentrations of greenhouse gases (GHG) produced by human activities. READ MORE

5. Advanced power cycles with mixture as the working fluid
Abstract : The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. READ MORE
