For modeling multi-phase where the disperse phase play a major role for determining the flow structure and inter phase transfer quantities, the size distribution of the particles has to be considered. This can be done by extension of the mass balance equation to a population balance equation. In this work, a least squares spectral method is tested for predicting the evolution of the disperse phase in a vertical two phases bubbly flow. The least squares spectral method consists in minimizing the L2 norm of the residual over the simulation domain. The results are compared with experimental data obtain for two different initial bubble distribution.
