A numerical model of time-resolved laser-induced incandescence (TIRE-LII) for different kinds of large carbonaceous particle is developed in this paper. Theoretical temporal LII signals were computed for the following classes of particles: soot, the well known hollow particles called cenospheres (tens of microns) and full carbonaceous particles called by analogy pleospheres (a few microns), pleo- from the Greek pleos (solid). The large carbonaceous particles have a characteristic time for internal gradient dissipation much longer than soot, thus a temperature profile establishes inside them. On the basis of these observations, a spatial time-dependent model for cenospheres and pleospheres was considered, i.e. a system of partial differential equations based on mass and energy balances.

A parametric modeling study on distributed MEMS transmission lines Unlu, M; Topalli, K; Demir, S; Aydın Çivi, Hatice Özlem; Koc, S; Akın, Tayfun (2004-10-14) This paper presents a parametric study of a new model for the distributed MEMS transmission line (DMTL) structures. In this new model, the MEMS bridges which are used as the loading elements of the DMTL structures are represented as low-impedance transmission lines, rather than a lumped CLR circuit. The model also includes LC networks at the transition points from the MEMS bridges to the unloaded parts of the DMTL which are simply high-impedance transmission lines. These LC networks are employed to model th...
A modeling recipe to optimize the nanostructure excitonic Dye Sensitized Solar Cells (DSSCs) Ameri, Mohsen; Mohajerani, E.; Samavat, F. (2017-01-01) A numerical modeling recipe has been established to perform a parametric simulation on the transport properties of charged species in dye sensitized solar cells (DSSCs). The main outputs of the simulation are the charged species densities and current voltage curve which determine the performance parameters of DSSC. But a realistic estimation of the performance parameters strongly depends on the number of physical parameters involved. To do so, we have attempted to engage the most recent theories in the pres...
A novel CEM technique for modeling electromagnetic scattering from metasurfaces ÖZGÜN, ÖZLEM; Mittra, Raj; Kuzuoğlu, Mustafa (Wiley, 2020-03-01) This paper presents a novel computational electromagnetics (CEM) technique, which hybridizes the periodic finite element method (FEM) with the method of moments (MoM), for efficient numerical modeling of electromagnetic scattering from metasurfaces consisting of truncated periodic or locally varying quasi-periodic array of structures. Based on the quasi-periodic nature of metasurfaces, the periodic FEM is employed to generate high-level macro basis functions (MBFs). Following that, a reduced MoM matrix is f...
A Novel Numerical Technique for Analyzing Metasurfaces ÖZGÜN, ÖZLEM; Mittra, Raj; Kuzuoğlu, Mustafa (2019-12-31) This work presents a novel technique for efficient numerical modeling of electromagnetic scattering from metasurfaces comprising of truncated periodic or locally-varying quasi-periodic surfaces. The proposed technique hybridizes the periodic Finite Element Method (FEM) with the Method of Moments (MoM) to develop an algorithm far more efficient than conventional numerical methods for electromagnetic scattering from arbitrary objects. The key feature of the proposed algorithm is that it takes advantage of the...
A variational multiscale constitutive model for nanocrystalline materials Gürses, Ercan (Elsevier BV, 2011-03-01) This paper presents a variational multi-scale constitutive model in the finite deformation regime capable of capturing the mechanical behavior of nanocrystalline (nc) fcc metals. The nc-material is modeled as a two-phase material consisting of a grain interior phase and a grain boundary effected zone (GBAZ). A rate-independent isotropic porous plasticity model is employed to describe the GBAZ, whereas a crystal-plasticity model which accounts for the transition from partial dislocation to full dislocation m...
