2.3 Solution Methods

As discussed in Chapter  1, the population balance equation can be solved by three different methods in ANSYS FLUENT: the discrete method, the standard method of moments (SMM), and the quadrature method of moments (QMOM). For each method, the ANSYS FLUENT implementation is limited to a single internal coordinate corresponding to particle size. The following subsections describe the theoretical background of each method and list their advantages and disadvantages.
