[ 1 ] - طراحی سنسور شش مؤلفه ای نیرو – گشتاور برای تونل کاویتاسیون

اندازه­گیری نیروهای هیدرودینامیکی روی اجسام زیر آب یکی از کاربردهای اساسی تونل آب می­باشد. برای این منظور، یک بالانس دقیق نیرو نیاز است. در این مقاله به طراحی یک بالانس کرنش­سنج شش مؤلفه­ای جدید، جهت اندازه­گیری نیروها و گشتاورهای وارده بر مدل بطور همزمان و مستقیم تحت شرایط با و بدون کاویتاسیون در تونل آب پرداخته شده­است. این بالانس، یک سازه پیچیده فنری است که از طریق اندازه­گیری کرنش ایجادشده ...

[ 2 ] - A two-dimensional numerical model of a planar solid oxide fuel cell

A two-dimensional CFD model of a planar solid oxide fuel cell (SOFC) has been developed.This model can predict the performance of SOFC at various operating and design conditions.The effect of Knudsen diffusion is accounted in the porous electrode (backing) and reaction zonelayers. The mathematical model solves conservation of electrons and ions and conservation ofspecies. The model is formulate...

[ 3 ] - طراحی شکل بدنه یک زیرسطحی خودکنترل با رویکرد مستقیم

The design process of Autonomous Underwater Vehicles (AUVs) involves several steps including design of body shape. Hydrodynamic design of the exterior hull shape is a main step of body shape design. The effective parameters in this process include the length of the nose and tail, the blunt sections of nose and tail as well as the profiles of the nose and the tail. In the presen...

[ 4 ] - شناسایی رفتار دینامیکی جریان ابرکاواک زایی

Studying the behaviour of supercavitation from the energy aspect can be divided into two sections. Studying the behavior of supercavitation in the flow field and in vicinity of the flow field. A large portion of field energy is kept in the field, and the rest of it distributed as noise (sound) out of the field. In this paper, harmonious structures of the field which are flowing as energy source...

[ 5 ] - Acoustic Model Identification Using Inverse Model

Sound measured at various points around the environment can be evaluated by a series of multi-pole sources and their acoustic strength can be acquired. In this numerical study, a method, called the inverse method, was examined to achieve this goal. A variety of arrangements of different sources were considered and the acoustic strength of these sources was acquired. Through the application of t...

[ 6 ] - Investigation of Hydrodynamic Derivatives of an AUV Based on the Water Tunnel Testing Maneuvers

Coefficients or hydrodynamic derivatives of autonomous underwater vehicles play a key role in their development. The most popular way for the estimation of coefficient is to implement captive model tests such as straight line tests and planar motion mechanism tests in towing tanks. In this paper, investigation of hydrodynamic derivatives was performed based on the water tunnel maneuvers. Forces...

[ 7 ] - توسعه مدل عددی-نیمه تجربی جهت تخمین مشتقات هیدرودینامیکی یک AUV

Increased use of Autonomous Underwater Vehicles (AUVs) caused an increase in their design sensitivity. The subject of most of AUV design studies was on drag reduction, ease of handling and their stability. Adequate design and prediction of the behavior of these vehicles requires an accurate estimation of corresponding hydrodynamic derivative loads. In this study, Hydrodynamic derivatives of the...
