Study of industrial titania synthesis using a hybrid particle-number and detailed particle model

Abstract

We apply a hybrid particle model to study synthesis of particulate titania under representative industrial conditions. The hybrid particle model employs a particle-number description for small particles, and resolves complicated particle morphology where required using a detailed particle model.

Stochastic population balance methods for detailed modelling of flame-made aerosol particles

“…images. It has been used in the MOpS particle simulator to study flame synthesis of titania (Lindberg et al, 2019a) and soot (Hou et al, 2019), finding good agreement with experiments, and to study industrial synthesis of titania (Boje et al, 2020), enabling comprehensive characterisation of structures developed under relevant conditions.

High-order polynomial approximations for solving non-inertial particle size density in flames

“…Numerous approaches and numerical methods have been discussed and applied [2][3][4][5][6][7][8][9][10][11] and many references therein. The thermophysical models are usually developed by comparing their predictions against experimental results after solving the PBE.…”

Solving the population balance equation for non-inertial particles dynamics using probability density function and neural networks: Application to a sooting flame

“…6 A large variety of methods for simulating the time evolution of PSD have been discussed in the literature and applied with success, including advanced numerical strategies proposed recently to address the issues mentioned above. [7][8][9][10][11][12][13] However for many of these approaches, securing accuracy in the PSD shape prediction goes with a large computing effort, jeopardising the systematic application of the most precise methods to three-dimensional and unsteady simulations for virtual prototyping of real systems. Advanced methods for solving the PSD have been applied to canonical problems featuring low or moderate Reynolds numbers studied with direct numerical simulation (DNS), [14][15][16] while simplified approaches are usually developed to deal with complex three-dimensional flows, specifically in the context of particulate emissions from burners and com-2 This is the author's peer reviewed, accepted manuscript.…”
