CFD Simulation of Solidification of non-Newtonian Fluid Flowing in a Complex Geometry Pipeline in Turbulent Flow Regime
Vesjolaja, Ludmila; Bujalski, Jakub M; Vågsæther, Knut (Journal article; Peer reviewed, 2018)In this CFD (Computational Fluid Dynamics) study, the turbulent flow of a non-Newtonian fluid through an industrial scale transportation pipeline is modelled in Ansys Fluent®, with a focus on the fluid solidification due ... -
Dynamics and Control for Efficient Fertilizer Processes
Vesjolaja, Ludmila (Doctoral dissertations at the University of South-Eastern Norway;105, Doctoral thesis, 2021-10-11)Granulation processes have been a subject of research for more than 60 years. During these years of research, there has been a significant improvement in qualitative and quantitative knowledge of the granulation processes, ... -
Population balance modelling for fertilizer granulation process
Vesjolaja, Ludmila; Glemmestad, Bjørn; Lie, Bernt (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 ...
