报告题目method of moments for resolving Polydispersed particle-laden flows

报告摘要:Population Balance Equation (PBE) is a general phenomenological mathematical framework involving huge numbers of inelastically colliding particle systems at different space and time scales, ranging from molecular to planetary and astrophysical scales. Despite its importance, an exact solution to the PBE that describes this system using real kernels has not been found.

In this conference report, the application of the Taylor series expansion technique in solving the PBE, i.e. Taylor series expansion method of moments (TEMOM), will be discussed. The technique was initially introduced for solving the PBE involving fine particle physicochemical processes, and its basic theory and applications have subsequently been developed further. The theories, implement criteria, and applications are presented here in a universal form for ease of use. The aforementioned method is mathematically economical and applicable to combination of colloid physicochemical processes, and can be used to numerically and pseudo-analytically describe the time evolution of statistical parameters governed by the PBE when coupled with Navier-Stokes equations. This report summarizes the principal details of the method, and discusses its application to fine particle engineering problems. The possible direction for the development of this method and its merits and shortcomings are also reported.
