1. 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

5. Energy simulation and life cycle costs : estimation of a building's performance in the early design phase
Abstract : Sustainable development and the protection of the environment are key issues in our society today. The building stock in Europe accounts for over 40% of the final energy consumption, CO2 emissions and generation of waste. A large part of the life cycle performance is determined early. READ MORE
