Taylor series expansion scheme applied for solving population balance equation

Abstract

<jats:title>Abstract</jats:title> <jats:p>Population balance equations (PBE) are widely applied to describe many physicochemical processes such as nanoparticle synthesis, chemical processes for particulates, colloid gel, aerosol dynamics, and disease progression. The numerical study for solving the PBE, i.e. population balance modeling, is undergoing rapid development. In this review, the application of the Taylor series expansion scheme in solving the PBE was discussed. 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 the combination of fine-particle physicochemical processes and can be used to numerically and pseudo-analytically describe the time evolution of statistical parameters governed by the PBE. This article summarizes the principal details of the method and discusses its application to engineering problems. Four key issues relevant to this method, namely, the optimization of type of moment sequence, selection of Taylor series expansion point, optimization of an order of Taylor series expansion, and selection of terms for Taylor series expansion, are emphasized. The possible direction for the development of this method and its advantages and shortcomings are also discussed.</jats:p>

Distribution of Nanoparticles in a Turbulent Taylor–Couette Flow Considering Particle Coagulation and Breakage

“…where M0 is the total particle number, M1 represents the particle volume and is proportional to the particle mass and M2 is directly relevant to the particle polydispersity. In this paper, the TEMOM [22,23] was used to close Equation (11). The basic idea of the TEMOM is to transform any moment into the form of the first three moments using the Taylor series expansion technique so that the moment equations can be solved in a closed way.…”

Thermodynamic Analysis of Brownian Motion-Induced Particle Agglomeration Using the Taylor-Series Expansion Method of Moments

“…The main objective of all MOMs is to achieve the closure of Equation ( 5). In the classic TEMOM, this is accomplished in two procedures [9,19]: (1) the collision kernel is directly approximated by a two-variable third-order Taylor series expansion, for example, the power function (υ −1 i + υ −1 j ) 1/2 in Equation ( 2) can be expanded with respect to mean volume u = M 1 /M 0 ; (2) and all the higher and fractional moments are approximated by the polynomial equation with respect to the first three moments:…”

“…Here the values x i are the pipeline partition points and y i = y P,i (pressure) or y i = y u,i (celerity) are generated data from solving Eqs (20) and (21). With replacing the polynomials P(x i ) and u(x i ) in the error function (24) we have…”
