A prestigious form of research grant in Germany is the
Sonderforschungsbereich, which provides continuous funding over a period
of up to 15 years, but only as long as the work is yielding worthwhile
results. We acknowledge financial support of our work at Erlangen by the
Deutsche Forschungsgemeinschaft (DFG), Sonder- forschungsbereich 222.
Thanks to this support, the experimental results from six Dr. -Ing.
dissertations have provided the basis for our book: 8 - Schweinzer, J.
(1987) Heat transfer in bubbling fluidized beds at Ar;a. 10 - Seiter, M.
(1990) Particle motion and solids concentration in circulating fluidized
beds - Mattmann, W. (1991) Heat transfer in pressurized circulating
fluidized beds - Burschka, A. (1993) Pulsed light method - Dietz, S.
(1994) Heat transfer in bubbling fluidized beds - Gruber, U. (1995) Heat
transfer in lean phase systems This book is the result of the
enthusiastic and trustful cooperation of its authors. Nevertheless, we
are separate individuals. Chapters 1 to 12 and 19 are by O. Molerus;
Chapters 13 to 18 are by K. -E. Wirth. This book came into existence
after many rewrites, patiently endured by Mrs Winter, who typed all
versions of the manuscript, and by Mrs Scheffler-Kohler, who drew all
the figures. Bob Farmer and David Penfold helped us bridge the language
gap to produce a readable book. Weare grateful to Professor Brian
Scarlett of Delft University, who on behalf of Chapman & Hall allowed us
to write this book.
