Over the past two years the Australian biodiesel industry has faced difficult times causing large scale producers to drastically curtail production with some even ceasing operation. This turn of events has highlighted the advantages of small scale production, which are investigated in depth in a companion paper (de Boer and Bahri 2009a). For small scale production to be viable the transesterifi...
This research describes aerodynamic characteristics of small-scale wind turbine blade, called Archimedes spiral wind turbine blade. Numerical approaches on the prediction of aerodynamic performance of the blade have been conducted. Both steady and unsteady state numerical simulations using ANSYS CFX are performed on the several cases of rotating speeds. Large scale tip vortex is captured and gr...
In axial flow compressor, blade surface roughness is affected by many failure modes such as fouling, erosion, corrosion and foreign object damage. But with development of filter performance, particles with diameter larger than 2 μm cannot enter into compressor, so fouling is the most important influence factor which results in the variation of surface roughness. This study respectively discusse...
Computational Fluid Dynamic (CFD) modeling of a continuous countercurrent hydrolysis process was performed using ANSYS-CFX. The liquid properties and flow behavior such as density, specific heats, dynamic viscosity, thermal conductivity, and thermal expansivity as well as water solubility of the hydrolysis components triglyceride, diglyceride, monoglyceride, free fatty acid, and glycerol were c...
استفاده از سرریزهای پلکانی، به علت هزینه ی ساخت پایین و بازدهی بالای آن، بطور فزاینده ای 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 زمینه ی سرریزهای پلکانی با ارتفاع پله یکنواخت می باشند، در حالی که ارتفاع پله غیریکنواخت نیز می تواند در بعضی حالات به عنوان یک گزینه مطرح گردد. در این تحقیق یک نمونه ی فیزیکی ا...
هدف این پروژه بررسی پایداری خودرو در اثر افزایش نیروهای آئرودینامیکی وارد بر خودرو در سرعت های بالا بوده است. به این منظور پس از بررسی پیشینه موضوع و کارهای انجام شده بر روی این موضوع در فصل اول ، در فصل دوم به بررسی روش های بدست آوردن اثرات آئرودینامیکی بر روی خودروی مدل طراحی شده، پرداخته شده است. همانطور که می دانیم تونل باد مهمترین ابزار برای بدست آوردن اثرات آئرودینامیکی است. برای این منظو...
Buoyancy driven flow is found in many engineering application such as the mixing of fluids with different densities. In nuclear reactor safety the mixing of borated and deborated water is a critical issue that needs investigation, assessment and prediction. As nuclear reactor geometries are complex, in this study a simple vertical mixing test facility (VeMix) was used to validate numerical mode...
Training equipment used by professional sportsmen has a great impact on their sport performance. Most universal exercisers may help only to improve the general physical condition due to the specific kinematics and peculiar resistance generated by their loading units. Training of effective techniques and learning of psychomotor skills are possible only when exercisers conform to the movements an...
Pump cavitation is the formation and subsequent collapse or implosion of vapor bubbles in a pump. It occurs when the absolute pressure on the liquid falls below the liquid’s vapor pressure. This paper describes the validation of cavitation inception on a radial flow pump which develops 21m of head at 26lps of discharge at its best efficiency point (BEP) of discharge while operating at a speed o...
