6. Hydrodynamics and Heat Transfer in Vertical Falling Films with Smooth and Modified Heat-Transfer Surfaces – An Experimental and Numerical Investigation
Sammanfattning : High energy utilization efficiency is important to achieve a sustainable society. By having highly efficient heat exchangers, more energy can be recovered and reused at a lower cost. LÄS MER
7. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System
Sammanfattning : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. LÄS MER
8. On-Engine Turbocharger Performance Considering Heat Transfer
Sammanfattning : 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. LÄS MER
9. Heat Transfer in Circulating Fluidized Bed Boilers
Sammanfattning : Heat transfer to single particles in the transport zone of circulating fluidized beds and heat transfer to membrane tube walls have been investigated. The heat transfer coefficient to spheres in the transport zone of a circulating fluidized bed boiler has been measured with dark and light calorimeters. LÄS MER
10. Heat-transfer simulations applied to electrical machines
Sammanfattning : Electrification and energy efficiency are two important aspects in present scenarios describing a sustainable future. Electric motors constitute a large fractionof industry’s electricity demand today, and it is expected to remain high inthe future. LÄS MER
