Fluidized Processes: Theory and PracticeAlan Wesley Weimer A peer-reviewed selection of 15 papers from a symposium series at the American Institute of Chemical Engineers, November 1991 in Los Angeles. For such fluid-particle systems as circulating fluidized beds, two-phase gas-solid and gas-liquid bubbling fluidized beds, three-phase magnetically stabilized |
