Transient Modeling Techniques for the Analysis of Electromagnetic Launchers
Tosun, Nail; Keysan, Ozan; Department of Electrical and Electronics Engineering (2021-9-7)
Although electromagnetic launchers (EMLs) are better than gun-powder-based launchers, they have to endure severe electrical and mechanical conditions. Therefore, the optimal design and accurate simulations of these devices are essential. The inductance and electromotive force (EMF) variations in the transient, which significantly impact the launch process, are modeled. Moreover, velocity skin effect (VSE) is added to the EML calculations in an effective way. Commercial finite element software cannot solve t...
Transient simulation of internal separated flows using an intelligent higher-order spatial discretization scheme
Oymak, O; Selçuk, Nevin (1997-04-30)
This paper summarizes the method-of-lines (MOL) solution of the Navier-Stokes equations for an impulsively started incompressible laminar flow in a circular pipe with a sudden expansion. An intelligent higher-order spatial discretization scheme, which chooses upwind or downwind discretization in a zone-of-dependence manner when flow reversal occurs, was developed for separated flows. Stability characteristics of a linear advective-diffusive equation were examined to depict the necessity of such a scheme in ...

Transient Stability Enhancement of the Power System Interconnected with Wind Farm Using Generalized Unified Power Flow Controller with Simplex Optimized Self-Tuning Fuzzy Damping Scheme
Vural, A. M.; Bayindir, K. C. (2012-07-01)
Due to increasing penetration of wind power into traditional grid, co-working of synchronous generators with wind turbines is gaining attention in terms of system stability. This paper deals with the transient stability enhancement of such systems by generalized unified power flow controller (GUPFC) having grid frequency switching quasi multi-pulse converters. Besides independent real and reactive power flow control capability of the two series converters, one series converter is commissioned to damp synchr...
Transient shape factors for dual-porosity simulation of tight rocks
Kilicaslan, Ufuk; Akın, Serhat (2021-05-01)
The shape-factor concept provides an elegant and powerful upscaling method for fractured reservoir simulation. Many different shape-factors, among which the well-known Warren and Root, and Kazemi shape-factors have been proposed in the past. Since different shape-factors can lead to totally different reservoir behavior, selection of the appropriate shape-factor value is critical for accurate fractured reservoir modeling. Constant shape factor is commonly used for simulation of fractured reservoirs by assumi...
