2. 1. Engine Optimized Turbine Design

   Author : Nicholas Anton; Anders Christiansen-Erlandsson; Magnus Genrup; Marc Gugau; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; Heavy-duty; Turbine; Axial; Radial; Machine Design; Maskinkonstruktion;

   Abstract : The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. READ MORE

4. 2. Thermodynamic Simulation of HCCI Engine Systems

   Author : Olof Erlandsson; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HAM; Turbine; Compressor; Turbocharger; Engine; Modeling; HCCI; Simulation; Motors and propulsion systems; Motorer; framdrivningssystem;

   Abstract : This thesis focuses on engine system simulation using thermodynamics and chemical kinetic models to investigate the performance and efficiency of Homogeneous Charge Compression Ignition (HCCI) engines for stationary applications. It includes the development of software as well as models for engine, turbocharger, intercooler, inlet and exhaust manifolds, wastegate valve, inlet air humidifier, inlet air heater and more.

5. 3. Design of an Experimental Facility for Investi- gating the Flow in a Low Pressure Turbine Exit Structure

   Author : Borja Rojo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbine Rear Frame; Turbine Exhaust Case; Experimental; Exit Guide Vane; Engine Exit Structure; Aerodynamics; Outlet Guide Vane; Gas Turbine; Wind Tunnel; Heat transfer.; CFD; Turbine Rear Structure;

   Abstract : This report presents the design of a turbine facility for investigating the flow in the EES located at Chalmers University of Technology. The EES is the structure located downstream of the LPT in a jet engine. In this rig, in order to generate realistic inlet boundary conditions for the EES, an LPT stage is located upstream of the EES.

6. 4. Developing Humidified Gas Turbine Cycles

   Author : Michael Bartlett; KTH; []
   Keywords : advanced gas turbine cycles; evaporative; humidified; power; heat and power;

   Abstract : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. READ MORE
