摘要：
An adaptive moving pivot technique for the solution of population balance equations is presented that extends previous pivot techniques (Kumar and Ramkrishna, Chem. Eng. Sci., 51(8): 1311-1332, 1996; 51(8): 1333-1342, 1996; 52(24): 4659-4679, 1997) in two ways. Firstly, equations are derived to guarantee the preservation of two arbitrarily chosen integral properties. Secondly, a grid adaptation strategy is proposed. With these extensions the scope of pivot techniques is significantly broadened. The growth term is now also preserving two arbitrarily chosen integral properties.
