Bivariate Taylor-series expansion Method of Moment for particle population balance equation in Brownian Coagulation
Journal of Aerosol Science, 2017Co-Authors: Jiang Zhi, Shen Jie, Lu ZhimingAbstract:Abstract In this study, we extend the Taylor-series expansion Method of Moment to two-component aggregation problem undergoing Brownian coagulation with kernels that are independent of composition. A set of closed particle population balance equation for lower-order Moments is then derived. Numerical results and its asymptotic solutions are validated by comparing with Monte Carlo simulation Method both in free molecular regime and continuum regime. It is shown that three dimensionless particle Moments M C 1 , M C 2 , M C 3 almost approach to a same value over large evolution time. The normalized variance of excess component A decreases as 1 / v ¯ and it tends to zero over large evolution time.

verification of expansion orders of the taylor series expansion Method of Moment model for solving population balance equations
Aerosol and Air Quality Research, 2015Co-Authors: Xiaotong Zhang, Yueyan Liu, Martin SeipenbuschAbstract:We verified the effect of the Taylor expansion order on the accuracy of the Taylor-series expansion Method of Moment (TEMOM) model in both the free molecular and continuum-slip regimes. The ordinary differential equations for Moments with fourth-order Taylor expansion were first derived for fractal-like agglomerates, which were further compared to the existing TEMOM model with third-order Taylor expansion. We confirmed that the TEMOM model with a fourth-order Taylor expansion is less accurate than that with a third-order Taylor expansion. Moreover, the scope of application of the TEMOM model with a fourth-order Taylor expansion is limited. The existing TEMOM model with a third-order Taylor expansion was verified as the most reliable model for solving population balance equations for agglomerates undergoing Brownian coagulation.

Quantitative spatial/spectral analysis of magnetic resonance imaging surface and phased array coils of arbitrary geometry based on Method of Moment
Proceedings of 18th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1Co-Authors: Fa-hsuan Lin, Syh-kang Jeng, Wei-peng Kuan, Jyh-horng ChenAbstract:Here we report a new generalized approach, based on Method of Moment, to the quantitative analysis of spectral/spatial properties of radio-frequency (RF) coils used in magnetic resonance imaging (MRI). This Method is especially powerful for phased array coils with the following abilities: (1) arbitrary coil geometry; (2) automatic calculation of complex current distribution, (3) B/sub 1/ homogeneity map and frequency response.
