2. 1. Fluid and suspension hydrodynamics in the impeller discharge flow of stirred tanks

   Author : Ziyun Yu; KTH; []
   Keywords : hydrodynamics; stirred tank; phase Doppler anemometer;

   Abstract : The hydrodynamics of an agitated tank have been studied byphase-Doppler anemometry. The focus is on the impeller anddischarge region of a 45o pitched blade turbine (PBT). Thestudy includes agitation of pure water as well as of a dilutesuspension of process particles. READ MORE

4. 2. Fundamental Mathematical Modeling of Gas Injection in AOD Converters with Emphasis on the Inlet

   Author : Anders Tilliander; KTH; []
   Keywords : AOD; nozzle; modeling; steel; fluid flow; gas injection.;

   Abstract : The overall purpose of the present work has been to developa novel mathematical model of the gas injection in the AODconverter process, based on fundamental transport equations.The model development was divided into two major steps, wherethe first step involved modeling of gas injection through acylindrical nozzle at high gas flow rates (the nozzle model).

5. 3. Experimental and numerical investigation of axial turbine models

   Author : Berhanu Mulu; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Abstract : Hydropower is a versatile renewable source of power generation able to change rapidly operating conditions. Hydropower plants may today work over a larger operating range than designed for due to the introduction of renewable sources of energy and the deregulation of the electricity market. READ MORE
