The book will provide methods necessary to analyze complex particulate systems and related phenomena. Physical, chemical and mathematical description of fundamental processes influencing crystal size and shape, suspension reology, interfacial area of drops and bubbles in extractors and bubble columns will be provided. Examples of mathematical model formulation for different processes taking place in such systems will be shown. Connections between turbulent mixing mechanism and precipitation will be discussed. The influence of fine-scale structure of turbulence, including its intermittent character, on breakage of drops, bubbles, cells, plant cell aggregates will be considered. Important aspect of the mathematical modeling presented in the book is multifractal approach applied to take into account the influence of internal intermittency on different phenomena.

About the Author

Wioletta Podgórska is a Professor in the Faculty of Chemical and Process Engineering at the Warsaw University of Technology, Poland, where she obtained her Ph.D. and D.Sc. Her main theoretical and experimental research touch such fields as turbulent mixing, chemical reaction, precipitation, liquid-liquid dispersions. She is an author of about 100 scientific papers and reports. The paper Mixing-precipitation model with application to double feed semibatch precipitation based on her Ph.D. thesis and published in Chemical Engineering Science, 1995, was taken into account during selection of most influential contributions to mixing research (AIChE Meeting for NAMF 21st anniversary celebration). Her monograph Drop breakup and coalescence in turbulent field (OWPW, 2006, in Polish) was awarded by Polish Academy of Sciences in 2007. Professor Podgórska is also a coauthor of textbook Computations in bioreactor engineering (1st ed. 1996, 2nd ed. 2012, in Polish).
