2. 1. Numerical Investigation of Turbulent Fluid Flow and Heat Transfer in Complex Ducts

   Author : Masoud Rokni; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SED; WET; GGDH; RNG; RSM; EASM; Low-Reynolds; Non-linear k-e; Heat transfer; Turbulent; Complex ducts; Secondary flows; Temperature invariance; Energy research; Energiforskning;

   Abstract : 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. READ MORE

4. 2. Jet Impingement and Infrared Heating of Cylindrical Foods. Flow and Heat Transfer Studies

   Author : Eva Olsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; fluiddynamik; plasma; Thermal engineering; applied thermodynamics; Gaser; fluid dynamics; plasmas; Gases; RSM; CFD; inverse heat transfer; jet impingement heat transfer; infrared heating; termodynamik; Food and drink technology; Livsmedelsteknik; PIV; SST; food; cylinder;

   Abstract : Rapid heat transfer methods such as jet impingement and infrared radiation can be used to speed up thermal processing in the food industry. The heating rate affects important food characteristics, such as colour. READ MORE

5. 3. Turbine Outlet Guide Vane Flows

   Author : Johan Hjärne; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spalart-Allmaras model; k-ω SST model; linear cascade; secondary flows; turbine exhaust casing; RSM; k-ε realizable model; turbine rear frame; engine mount bump; tail bearing housing; Outlet guide vane;

   Abstract : New design goals on modern jet engines often leads to more highly loaded turbines with fewer stages in order to save weight and cost. This gives higher swirl angles into the outlet guide vane (OGV), implying a more difficult aerodynamic design. READ MORE

6. 4. Carbide and MAX-Phase Engineering by Thin Film Synthesis

   Author : Jens-Petter Palmquist; Ulf Jansson; M. Jochen Schneider; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Thin films; microstructure; epitaxy; carbide; WC; MAX-phase; Ti3SiC2; DC magnetron sputtering; PVD; Reciprocal Space Mapping; RSM; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Abstract : This thesis reports on the development of low-temperature processes for transition metal carbide and MAX-phase thin film growth. Magnetron sputtering and evaporation, far from thermodynamical equilibrium, have been utilised to engineer the properties of the films by physical and chemical control. READ MORE

7. 5. Optimization of Castings by using Surrogate Models

   Author : Erik Gustafsson; Niclas Strömberg; Bo Torstenfelt; Linköpings universitet; []
