Model Based Unbalance Identification for Paper Machine's Tube Roll
(Springer, Cham, 2019-06-14)
Mass unbalance is a major concern in modern day rotating machinery. For single and double disc rotor bearing systems, model based techniques have been used to identify the unbalance. The aim of this research is to predict ...
Modeling of industrial-scale sorption enhanced gasification process: One-dimensional simulations for the operation of coupled reactor system
(Elsevier, 2021-03-23)
Sorption enhanced gasification (SEG) is a promising technology for producing gas derived from renewable feedstock to be used in biofuel synthesis processes. As a response to the growing need for renewable fuels, an SEG ...
Hydrothermal carbonization of lignocellulosic agro-forest based biomass residues
(Elsevier, 2021-02-25)
To increase the understanding of hydrothermal carbonization (HTC) of lignocellulosic biomass residues, four feedstocks: giant bamboo, coffee wood, eucalyptus, and coffee parchment, were studied. The effect of operating ...
Assessing the performance of deep learning models for multivariate probabilistic energy forecasting
(Elsevier, 2021-01-16)
Deep learning models have the potential to advance the short-term decision-making of electricity market participants and system operators by capturing the complex dependences and uncertainties of power system operation. ...
Variable-speed-drive-based method for the cost optimization of air filter replacement timing
(Elsevier, 2021-03-13)
The flow resistance of air filters accounts for a significant share of the electric energy consumed by fan systems. Due to their inevitable fouling, filters must be replaced periodically. This paper presents a novel ...
Decentralized cooperative scheduling of prosumer flexibility under forecast uncertainties
(Elsevier, 2021-03-10)
Scheduling of prosumer flexibility is challenging in finding an optimal allocation of energy resources for heterogeneous prosumer goals under various forecast uncertainties and operation constraints. This study addresses ...
Magneto-Thermal Analysis of an Axial-Flux Permanent-Magnet-Assisted Eddy-Current Brake at High-Temperature Working Conditions
(IEEE, 2020-05-07)
This paper proposes an analytic coupled magneto-thermal analysis of an axial-flux (AF) permanent-magnet-assisted (PMA) eddy-current brake (ECB) at high-temperature working conditions. In the topology investigated, permanent ...
Validation of the Axial Thrust Estimation Method for Radial Turbomachines
(Hindawi, 2021-02-24)
The fast preliminary design and safe operation of turbomachines require a simple and accurate prediction of axial thrust. An underestimation of these forces may result in undersized bearings that can easily overload and ...
Wheel–rail contact simulation with lookup tables and KEC profiles: a comparative study
(Springer Nature, 2020-12-18)
This paper describes and compares the use and limitations of two constraint-based formulations for the wheel–rail contact simulation in multibody dynamics: (1) the use of contact lookup tables and (2) the Knife-edge ...
Pool stratification and mixing induced by steam injection through spargers: CFD modelling of the PPOOLEX and PANDA experiments
(Elsevier, 2019-03-29)
Spargers are multi-hole injection pipes used in Boiling Water Reactors (BWR) and Generation III/III+ Pressurized Water Reactors (PWR) to condense steam in large water pools. During the steam injection, high pool surface ...
