1. 1. Hydrodynamics, Erosion and Heat Transfer in Pressurized Fluidized Beds

   Författare :Jan Wiman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; hydrodynamics erosion; heat transfer; tubes; fluidized bed; gas flow; pressurized fluidized bed; bubble;

   Sammanfattning : Measurements of hydrodynamics, local tube erosion and local instantaneous bed-to-tube heat transfer were carried out in a cold, pressurized, fluidized bed with different horizontal tube banks. The influence of pressure, fluidization velocity, particle size and tube-bank geometry was studied. LÄS MER
