1. 1. Fluidized Bed Operating Parameters and Eulerian Erosion Models

   Författare :Mattias Gustavsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Eulerian erosion model; fluidized bed; distributor plate; slugging; plenum chamber; brittle; two-fluid model; ductile; air-feed system;

   Sammanfattning : A numerical two-fluid code, Gemini 2D, was adapted to study gas-solid fluidization in arbitrary 2D domains. The code was also used to study fluid dynamic mechanisms of dense particle flow that cause ductile and brittle erosion of solids. LÄS MER

3. 2. Thermal and hydraulic performance of compact brazed plate heat exchangers operating as evaporators in domestic heat pumps

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; plate heat exchanger; evaporator; heat pump; flow boiling; pressure drop; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : This thesis investigates the performance of compact brazed plate heat exchangers (CBE) operating as evaporator in heat pump applications. The thesis, and the performances investigated, has been divided into three main sections; One zone evaporator performance; Two zone evaporator performance; and finally Local performance. LÄS MER

4. 3. Heat and Mass Transfer Investigations of Relevance for Food Engineering Applications

   Författare :Dirk Sterner; Värmeöverföring; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; mathematical modelling; frozen and non-frozen food; minced beef patties; cooking; heat and mass transfer; plate heat exchangers; evaporation;

   Sammanfattning : This thesis concerns two interrelated subjects of heat and mass transfer processes. The first one concerns mainly experimental measurements, with a subsequent development of a calculation procedure, of the thermal and hydraulic performances, experimental methods and evaluation procedures applied on various plate heat exchangers (PHEs) as evaporators with the refrigerant ammonia as working medium.

   Sammanfattning : Proton exchange membrane fuel cells (PEMFCs) are considered as the mostpromising alternative power sources with a wide variety of applications owing to their attractive advantages compared to other conventional power sources. During the past decades, the cell performance has been gradually improved. LÄS MER

7. 5. Performance analysis of a low-speed high-torque hydrostatic transmission unit

   Författare :Håkan Olsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

   Sammanfattning : This thesis concerns a study of the performance of an industrial low-speed high-torque hydrostatic drive system. This type of hydrostatic transmission is commonly used in continuous operation in a wide range of heavy-duty drive applications. In many applications the transmissions have to compete with e.g. LÄS MER
