This paper deals with the study of a flow field and namely configuration shock waves in blade cascade equipped part-span connector called tie-boss. The consists prismatic blades formed from mid-section very long last-stage steam turbine. is based on numerical simulations through that was previously tested wind tunnel. Commercial software Ansys CFX used for ICEM mesh generation. computational do...
In the present study, the antioxidant capacity of vitamin C was examined in the liver and the kidney tissues of mice with or without ciprofloxacin (CFX) treatment. The antioxidant capacity of the vitamin was evaluated in terms of lipid hydroperoxides (LOOH) and thiobarbituric acid reactive substances (TBARs). The experimental design was 15 days of water (control and CFX groups) or vitamin C (vi...
Preclinical Research The aim of this study was to determine the antiallodynic effect of acute administration of the β-lactam antimicrobials, ceftriaxone (CFX) and clavulanic acid (CLAV), for the control of established pain on a model of neuropathic pain (NP). We also investigated the involvement of dopaminergic and opioidergic pathways as well as alterations in serum concentrations of TNF-α in ...
Coronary spasm can occur in the presence or absence of coronary artery disease. We therefore determined the effect of preexisting coronary stenosis on the incidence of ventricular fibrillation during reperfusion after circumflex artery (CFX) occlusion. Twenty dogs underwent a 30-minute open-chest CFX occlusion. During reperfusion, CFX blood flow was restricted by a partial occluder. In dogs tha...
جریان غلیظ یکی از اصلی ترین عوامل انتقال مواد رسوبی به نزدیکی بدنه سد می باشد. در این مقاله با استفاده از روش عددی المان محدود، با استفاده از نرم افزار ansys-cfx به بررسی تأثیر زبری، الگوی قرارگیری، ارتفاع و شکل زبری ها در کف بر کنترل جریان غلیظ ورودی به مخازن سدها پرداخته شده است. جهت حل معادلات آشفتگی از روش k-ε استفاده شده است. پس از صحت سنجی مدل ، ابتدا جریان بدون وجود زبری ها مدل گردیده و ...
استفاده از سرریزهای پلکانی، به علت هزینهی ساخت پایین و بازدهی بالای آن، بطور فزایندهای رو به افزایش است. از این رو، مطالعات نیز در این زمینه با رشد و توجه زیادی از سوی مهندسین سدساز همراه بوده، ولی اغلب این مطالعات در زمینهی سرریزهای پلکانی با ارتفاع پله یکنواخت میباشند، در حالی که ارتفاع پله غیریکنواخت نیز میتواند در بعضی حالات به عنوان یک گزینه مطرح گردد. در این تحقیق یک نمونهی فیزیکی ا...
Bu çalışmada Dicle Üniversitesi Mühendislik Fakültesinin rüzgâr ve sıcaklık etkileri nümerik olarak incelenmiştir. Çalışma 4 durumda ele alınmıştır. Sırasıyla rüzgârın güneydoğu (ön kısım), kuzeybatı (arka kuzeydoğu (sağ kısım) güney batı (sol kısım)’dan esmesi durumunda bina üzerindeki akış özellikleri hesaplamalı akışkanlar dinamiği uygulamalarında sıklıkla kullanılan ANSYS CFX yazılım progra...
A new composite poly(caprolactone) (PCL) and poly(acrylic acid) (PAA) (PCL:PAA 1:5) scaffold was synthesized via dispersion of PCL particles into a PAA network. Silica microspheres (Si) (2–12 μm) were then prepared by a lyophilized micro-emulsion/sol-gel (Emugel) system using varying weight ratios. The model drug ciprofloxacin (CFX) was used for in situ incorporation into the scaffold. The phys...
This paper presents the coupled code system of PROTEUS-NODAL and SAM developed for multiphysics simulation molten salt reactors (MSRs). The coupling was made under MOOSE framework by developing a wrapper master application that controls neutronics thermal-fluidic calculations. verified validated using Molten Salt Fast Reactor (MSFR) benchmark problem available experimental data Experiments (MSR...
Influence of insertion of holes in the middle of obstacles on the flow around a surface-mounted cube
The aim of our study is to analyze the impact of insertion holes in the middle of obstacles on the flow around a surface-mounted cube, In order to do this; we studied four configurations of obstacles in a channel with a Reynods number based on obstacle height ReH = 40000. The hexahedral structured meshes were used to solve the fluid dynamics equations .The finite volume method are employed to s...
