21. Improved Energy Efficiency in the Aluminium Industry and its Supply Chains
Abstract : Energy is an essential resource in the daily lives of humans. However, the extraction and use of energy has an impact on the environment. The industrial sector accounts for a large share of the global final energy use and greenhouse gas (GHG) emissions. The largest source of industrial GHG emissions is energy use. READ MORE

22. Aerodynamic Investigations of a High Pressure Turbine Vane with Leading Edge Contouring at Endwall in a Transonic Annular Sector Cascade
Abstract : Efficiency improvement is an important aspect to reduce the use of fossil-based fuel in order to achieve a sustainable future. Gas turbines are mainly fossil-fuel based turbomachines, and, therefore, efficiency improvement is still the subject of many on-going research activities in the gas turbine community. READ MORE

23. Design and experimental studies of a biomass fired furnace for small- and medium scale heating applications
Abstract : The main objective of the work was to develop a biomass fired furnace for small and medium scale heating systems, which has the ability to manage wet as well as unclassified biofuels with maintained low emissions of harmful substances. The system should also be able to cope with large and frequently occurring thermal output variations fulfilling rigorous environmental restrictions. READ MORE

25. Interaction of sound waves with a swirl stabilized wood powder flame and their effects on flame characteristics
Abstract : Swirling flows have been widely used for many years in engineering applications such as; chemical and mechanical mixing devices, separation units, spray drying technologies, turbo machinery and combustion systems. In practical combustion applications, swirl motion has been adopted to the incoming reactant flows in order to enhance the mixing of fuel and oxidizer and to improve flame stabilization and establishment, especially in regions of relatively low velocities, by recirculating hot product gas to the incoming reactants.
