OMJulia: An OpenModelica API for Julia-Modelica Interaction
(Peer reviewed; Journal article, 2019)Modelica is an object oriented, acausal equation-based language for describing complex, hybrid dynamic models. About ten Modelica implementations exist, of which most are commercial and two are open source; the implementations ... -
Online Drilling Fluid Flowmetering in Open Channels with Ultrasonic Level Sensors using Critical Depths
(Journal article; Peer reviewed, 2017)In drilling operations, non-Newtonian drilling fluid is continuously circulated in a closed loop. One of the ways to monitor and regulate drilling operations is by accurately measuring the flow rate of circulating drilling ... -
Open Active Contour Model For Front Tracking Of Detonation Waves
(Journal article; Peer reviewed, 2017)This paper presents an image processing framework for tracking the front of the detonation wave from a sequence of images. The images are captured by high speed camera during a laboratory gas explosion experiment. By ... -
Optimal Operation of the Peat Drying Process in Steam Tube Dryers
(Journal article; Peer reviewed, 2015-11-25)Ukraine is an energy-dependent country and aims to reduce the import of natural gas, heat, and power in general. This implies extracting fuel from her own natural resources; one relevant and readily available energy carrier ... -
Population balance modelling for fertilizer granulation process
(Journal article; Peer reviewed, 2018)Few granulation plants are operated optimally. It is common to operate granulation plants below their maximum design capacity, and in many cases, periodic instabilities may also occur. From a process control and optimization ... -
Pressure wave propagation in Managed Pressure Drilling- model comparison with real life data
(Peer reviewed; Journal article, 2019)Drilling for oil and gas is a complex process, involving pumping of fluid through kilometers of pipes. Even though the drilling fluid has a high speed of sound (˜1000 m/s), the large lengths involved make pressure wave ... -
Second Order KP Scheme for the Solution of flow in a Venturi Channel
(Journal article; Peer reviewed, 2018)In many different applications, a Venturi channel is used as a tool to compute fluid flow rates. The Saint-Venant equation is a hyperbolic type Partial Differential Equation (PDE) which can be used to model fluid flows ... -
Sensor placement and parameter identifiability in grey-box models of building thermal behaviour
(Journal article; Peer reviewed, 2019)Building energy management systems can reduce energy consumption for space heating in existing buildings, by utilising Model Predictive Control. In such applications, good models of building thermal behaviour is important. ... -
Simulation of the Pyrolysis Process: from Plastic Waste to Environmental Friendly Fuel
(Journal article; Peer reviewed, 2018)How to deal with plastic waste is an important question, as it may affect both the climate and environment. A method that may be beneficial to dispose some kinds of plastic waste that cannot be material-recycled is ... -
Simulation of Transcritical Flow in Hydraulic Structures
(Journal article; Peer reviewed, 2015-11-25)In hydraulic engineering, transcritical flows are often required in some applications. One example is in a Venturi channel where the occurrence of critical depth is used to estimate flow rate in the channel. In this paper, ... -
Simulations and real applications of PI and MPC averaging level control in a water resource recovery facility
(Journal article; Peer reviewed, 2018)The basin level control system in an existing wastewater treatment plant is designed for two different operation modes: compliant level control for smooth pump flow, and stiff level control. Both a model-based predictive ... -
Spray drop size characterization in an external-mixing bluff-body atomizer based on acoustics and Multivariate Analysis
(Peer reviewed; Journal article, 2022)Air-assist atomizers have been widely used in various applications such as the aerospace industry, internal combustion engines, molten metal, food processing, etc. The mean drop size for these atomizers was obtained through ... -
State Estimation of a Thermal Model of Air-cooled Synchronous Generator
(Peer reviewed; Journal article, 2019)In this paper, we extend a previous study on a totally enclosed thermal model of a synchronous generator, with temperature state estimation using experimental data. The extension includes a new formulation of the system ... -
Structural analysis in Julia for dynamic systems in OpenModelica
(Peer reviewed; Journal article, 2019)In control theory for dynamic systems, the information about observability and controllability of states plays a key role to evaluate the possibility to observe states from outputs, and use inputs to move states to a desired ... -
