Alatan, Lale; Leblebicioğlu, Mehmet Kemal (1999-04-01)
Derivation of the closed-form Green's functions and analytical evaluation of the method of moments (MOM) matrix entries have improved the computational efficiency of the significantly in the analysis of printed geometries. With this background in mind, an extension of this efficient numerical technique is to incorporate an optimization algorithm and to assess its potential as a computer-aided design (CAD) tool. Therefore, we have employed the Gradient search and Genetic algorithms, in conjunction with the e...
Use of detached eddy simulation for aerodynamics and aeroacoustics of blade sections
Cengiz, Kenan; Özyörük, Yusuf; Department of Aerospace Engineering (2018)
Investigation of noise generation mechanisms due to turbulence necessitates resolution of eddies in space and time. Among the broad-band noise simulation tools, direct numerical simulation (DNS) is the most comprehensive one. However, it is prohibitively expensive. At the other extreme, unsteady Reynolds-averaged Navier-Stokes (URANS) based solvers, which are widely used in industry, can merely be reliable for attached flows. Besides, the inherent time-averaging procedure destroys the unsteadiness of eddies...

Use of Asymptotic Waveform Evaluation Technique in the Analysis of Multilayer Structures With Doubly Periodic Dielectric Gratings
Gudu, Tamer; Alatan, Lale (Institute of Electrical and Electronics Engineers (IEEE), 2009-09-01)
The reflection and dispersion characteristics of multilayer structures that involve periodically implanted material blocks are obtained by using the MoM solution of the volume integral equation. The asymptotic waveform evaluation (AWE) technique is utilized to obtain a Pade approximation of the solution in terms of a parameter such as frequency or incident angle. The use of AWE technique enables a fast sweep with respect to the approximation parameter. Moreover, a robust method for extracting the dispersion...
