1. 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
2. Advances in Ventilation Heat Recovery : An assessment of peak loads shaving using renewables
Sammanfattning : The building sector accounts for approximately 40% of total global energy usage.In residential buildings located in cold climate countries, 30-60% of this energy isused for space heating, 20–30% is lost by discarded residential wastewater, and therest is devoted to ventilation heat loss. LÄS MER
3. 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
4. Flow and heat transfer in a turbocharger radial turbine
Sammanfattning : In the past decades, stricter legislation has been imposed to improve fuel economy and to reduce tail-end emissions of automotive vehicles worldwide. One of the important and effective technologies adopted by the automobile manufacturers to fulfill legislation requirements is the turbocharger technology. LÄS MER
5. Numerical Investigation of Turbulent Fluid Flow and Heat Transfer in Complex Ducts
Sammanfattning : Th need for a reliable and reasonable accurate turbulence model without specific convergence problem for calculating duct flows in industrial applications has become more evident. In this study a general computational method has been developed for calculating turbulent quantities in any arbitrary three dimensional duct. LÄS MER
