The switching device turn-on and turn-off process will produce high-frequency electromagnetic interference, based on the finite element method ANSYS software with powerful computing capabilities, has been widely used in complex electromagnetic field calculations. In this paper, ANSYS software to model and analyze the insulated gate bipolar transistor (IGBT) and quantitative distribution of elec...

Intestinal absorption of beta-lactamine antibiotics (e.g., cefixime and cephalexin) has been shown to proceed through the dipeptide carrier system. In a previous study, nifedipine (NFP), an L-type calcium channel blocker, enhanced the absorption of cefixime in vivo but not in vitro, and it was suggested that neural mechanisms might be involved in the effect of NFP. The aim of the present study ...

Centrifugal pump is widely used and plays an important role in national economy. However, according to plenty of engineering practice model tests, it indicated that the clearance between impeller cover parameter for leakage loss hydraulic efficiency. In this paper, a single stage centrifugal was selected study influence on performance through combination experiment numerical simulation. Commerc...

The modern development in mathematics bridges this gap (see Fig. 1). It allows us to start from a high dimensional system obtained by finite elements and then automatically generate a low dimensional approximation. The dimension of a reduced model is controlled by the approximation error specified by the user. In this article the software MOR for ANSYS [1] is presented. MOR for ANSYS applies ne...

ABSTRACT: This paper describes analysis of deep beams subjected to two point loading with three different L/D ratios (1.5, 1.6, 1.71) using Non-linear Finite element method (ANSYS 9.0 software) in order to investigate the stress and strain distribution pattern at mid-section of the beam. In ANSYS 9.0 software, SOLID 65 and LINK 8 element represent concrete and reinforcing steel bars. Non-linear...

مدلسازی فیزیکی همراه با استفاده از مدل­های عددی  با دقت مطلوب برای شرایطی که امکان مدلسازی به ازای دبی­های زیاد در آزمایشگاه به دلیل محدودیت­های هیدرولیکی و فیزیکی میسر نباشد امری اجتناب­ناپذیر است. در این تحقیق، ضمن اندازه­گیری­های مدل فیزیکی، از مدل عددی المان محدود ANSYS CFX برای شبیه­سازی عددی میدان جریان شامل سرعت، فشار و ضریب کاویتاسیون برای مدل سریز سد آزاد استفاده شده است. به کمک دو معی...

The separation process of oily water using membranes has attracted the attention researchers and engineers. greater problem in use membrane is reduction permeate flux due to clogged pores by oil deposition inside or effect concentration polarization. For this purpose, a theoretical study water/oil module was performed. This device consists tubular ceramic provided with rectangular inlet section...
