2. 1. Heat and Mass Transfer in Impingement Cooking. Aspects of Food Quality

   Author : Urban Wählby; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cooking; impingement; meat; mass transfer; buns; food quality; heat transfer;

   Abstract : Hot air impingement is a special form of forced convection, where the air is focused through the use of nozzles at a surface. In combination with rather high air velocities, a jet like phenomenon can evolve, which when used in for example cooking can achieve high heat transfer capacities. An Impingement oven prototype was constructed. READ MORE

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

   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. Modelling of Jet impingement Heat Transfer for Cooling of Cylindrical Foods

   Author : Eva Olsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiple jets; Nusselt number; cooling; sinle jet; Jet impingement heat transfer; CFD; cylinder; SST; food;

   Abstract : Cooling is an energy consuming operation in the food industry. Rapid cooling reduces the risk of growth of micro-organisms, improves the quality of the food product and increase the production rate... READ MORE

6. 4. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors

   Author : Andreas Abdon; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; plasma; combustor; gas turbine; cooling; numerical simulations; turbulence; ribs; impingement; Gases; fluid dynamics; plasmas; fluiddynamik; Gaser; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

   Abstract : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. READ MORE

7. 5. Experimental Study of Outlet Guide Vane Heat Transfer and Gas Turbine Internal Cooling

   Author : Chenglong Wang; Värmeöverföring; []
   Keywords : ;

   Abstract : Heat transfer in gas turbine related applications is investigated by steady state liquid crystal thermography (LCT) in this thesis. The work presented includes outlet guide vane heat transfer and gas turbine internal cooling. READ MORE
