We present a successful deployment of high-fidelity large-eddy simulation (LES) technologies based on spectral/$hp$ element methods to industrial flow problems, which are characterized by high Reyn...
In this paper we implement the element-by-element preconditioner and inexact Newton-Krylov methods (developed in the past) for solving stabilized computational fluid dynamics (CFD) problems with spectral methods. Two different approaches are implemented for speeding up the process of solving both steady and unsteady incompressible Navier-Stokes equations. The first approach concerns the applica...
Fourier spectral analysis of forearm skin laser Doppler flowmetry (LDF) signal was performed in fifteen hypercholesterolemic patients (HP), without clinically manifest arterial diseases, and in fifteen age-matched healthy control subjects (CS), in order to investigate skin blood flowmotion (SBF). The LDF frequency intervals studied were: 0.01-1.6 Hz total spectrum, as well as 0.01-0.02 Hz (endo...
In this paper we study the heat trace expansion of the perturbed harmonic oscillator by adapting to the semiclassical setting techniques developed by Hitrick-Polterovich in [HP]. We use the expansion to obtain certain inverse spectral results.
فاضلاب واحدهای چاپ و رنگرزی در صنایع نساجی اغلب حاوی رنگ و مواد شیمیایی هستند. یکی از رنگ¬های مورد استفاده در این صنعت، رنگ آلیزارین زرد می¬باشد که دارای ترکیبات معطر، هتروسیکلیک، بسیار پایدار بوده و باعث سخت شدن فرآیند حذف رنگ از فاضلاب می¬شوند. در این تحقیق، جاذب¬های h5pv2w10o4 (hp)، hp+co و hp+co+k ساخته شد. جذب رنگ آلیزارین زرد بوسیله جاذب¬های hp، hp+co و hp+co+k توسط فرآیند جذب سطحی بررسی ...
Nektar++ is an open-source software framework designed to support the development of highperformance scalable solvers for partial differential equations using the spectral/hp element method. High-order methods are gaining prominence in several engineering and biomedical applications due to their improved accuracy over low-order techniques at reduced computational cost for a given number of degr...
We review the basic algorithms of spectral/hp element methods on tetrahedral grids and present newer developments on hybrid grids consisting of tetrahedra, hexahedra, prisms, and pyramids. A unified tensor-product trial basis is developed for all elements in terms of non-symmetric Jacobi polynomials. We present in some detail the patching procedure to ensure C continuity and appropriate solutio...
