Computational fluid dynamic simulations of thermochemical conversion of pulverized biomass in a dilute flow using spheroidal approximation
(Peer reviewed; Journal article, 2020)A drag force model for spheroids, referred as the spheroid model, was implemented in OpenFOAM, in order to better predict the thermochemical conversion of pulverized biomass. Our previous work has found that the spheroid ... -
Thermodynamic properties of the 3D Lennard-Jones/spline model
(Peer reviewed; Journal article, 2019)In the Lennard-Jones spline (LJ/s) model, the Lennard-Jones (LJ) potential is truncated and splined so that both the pair potential and the force continuously approach zero at rc ≈ 1.74σ. It exhibits the same structural ... -
Data-driven modeling of a CO2 refrigeration system
(Peer reviewed; Journal article, 2019)This paper describes a data-driven method for system identification of a CO 2 refrigeration system. Traditionally, the interaction between the measured variables is not utilized as they are highly dependent on the refrigeration ... -
Uncertainty assessments of structural loading due to frst year ice based on the ISO standard by using Monte-Carlo simulation
(Peer reviewed; Journal article, 2020)Sea ice is the major source of loading for structural design in cold regions. The intrinsic properties of sea ice are generally associated with high degrees of uncertainty due to ice growth taking place during different ... -
A novel hybridized metaheuristic technique in enhancing the diagnosis of cross-sectional dent damaged offshore platform members
(Peer reviewed; Journal article, 2019)Offshore jacket platforms are widely used for oil and gas extraction as well as transportation in shallow to moderate water depth. Tubular cross‐sectional elements are used to construct offshore platforms. Tubular cross ... -
