Development of a Moving Front Kinetic Monte Carlo Algorithm to Simulate Moving Interface Systems
Chaffart, Donovan (University of Waterloo, 2023-06-02)Moving interfaces play vital and crucial roles in a wide variety of different natural, technological, and industrial processes, including solids dissolution, capillary action, sessile droplet spreading, and superhydrophobicity. ... -
Modelling and optimization of a pilot-scale entrained-flow gasifier using artificial neural networks
Wang, Han; Chaffart, Donovan; Ricardez-Sandoval, Luis A. (Elsevier, 2019-12-01)This paper explores the construction and validation of an artificial neural network (ANN) in order to accurately and efficiently predict the performance of a pilot-scale gasifier unit. This ANN model consists of multiple ... -
Optimization and control of a thin film growth process: A hybrid first principles/artificial neural network based multiscale modelling approach
Chaffart, Donovan; Ricardez-Sandoval, Luis A. (Elsevier, 2018-11-02)This work details the construction and evaluation of a low computational cost hybrid multiscale thin film deposition model that couples artificial neural networks (ANNs) with a mechanistic (first-principles) multiscale ... -
Uncertainty Analysis and Robust Optimization of a Single Pore in a Heterogeneous Catalytic Flow Reactor System
Chaffart, Donovan (University of Waterloo, 2017-08-31)Catalytic systems are crucial to a wide number of chemical production processes, and as a result there is significant demand to develop novel catalyst materials and to optimize existing catalytic reactor systems. These ...
