Modeling of the nonlinear behavior of steel framed structures with semi rigid connections
Sarıtaş, Afşin; Özel, Halil Fırat (null; 2015-07-21)
A mixed formulation frame finite element with internal semi-rigid connections is presented for the nonlinear analysis of steel structures. Proposed element provides accurate responses for spread of inelasticity along element length by monitoring the nonlinear responses of several crosssections, where spread of inelasticity over each section is captured with fiber discretization. Each material point on the section considers inelastic coupling between normal stress and shear stress. The formulation of the ele...
Modeling of radiative heat transfer in strongly forward scattering media of bubbling fluidized bed combustor with and without recycle
Şen, Özge; Külah, Görkem; Selçuk, Nevin; Department of Chemical Engineering (2017)
Predictive accuracy and CPU efficiency of geometric optics approximation (GOA) and scattering phase function simplifications in the freeboard of lignite-fired METU 0.3 MWt ABFBC Test Rig were tested by applying them to the modeling of radiative heat transfer and comparing their predictions against measurements and benchmark solutions. The freeboard was treated as 3-D rectangular enclosure containing grey, absorbing, emitting gas with grey, absorbing, emitting, non/isotropically/anisotropically scattering pa...
Modeling of fluid -vapor interface in the condensation zone of a grooved heat pipe
Alipour, Mobin; Dursunkaya, Zafer; Department of Mechanical Engineering (2017)
Condensation in grooved heat pipes involves several simultaneous phenomena including vapor-liquid boundaries whose shapes are unknown a priori, fluid flow due to capillary and dispersion pressure gradients and condensation over ultra thin films. In grooved heat pipes, the majority of condensation occurs on fin tops due to the thinner liquid film, having a lower thermal resistance, compared to inside the groove where the fluid is substantially thicker. Majority of the studies in the literature assume an appr...
Modeling of Multi Open Phase Fault Condition of Multi-phase Permanent Magnet Synchronous Motors
Fei, Marco; Zanasi, Roberto (2011-09-10)
This paper deals with the modeling of multi-phase permanent magnet synchronous motors under multi open phase fault condition. The presented model is suitable for generic number of phases, generic shape of the rotor flux and generic number of open circuit faults. The motor model in fault condition can be used for faults occurring on both adjacent and not adjacent phases. The model can be very useful both for simulation and implementation of fault-tolerant control strategies.
