 July 8, 2008, 15:12 Population Balance Theory #1 student Guest   Posts: n/a Am interested in doing mathematical and theoretical research in the Population Balance field. I did Google search but become more confused. Hope someone can answer my questions. 1/ What is the population balance theory. 2/ What is population balance equation(S) 3/ what is the relationship between population balance equations and incompressible and compressible flow, and CFD 4/ where I MUST start 5/ is population balance equation(S) are a general case of multiphase flows 6/ any information about the mathematical descripption (NO commercial software please) 7/ I did search in Wiki-CFD and could not find any information. We may therefore but your answers in our Wiki Am quite sure somebody out there can give us more information. Thank you for your assistant and consideration Best regards, Student
