INVESTIGATION AND OPTIMIZATION OF WINGLETS FOR HAWT ROTOR BLADES Elfarra, Monier A.; Akmandor, I. Sinan; Sezer Uzol, Nilay (2011-03-25) The main purpose of this paper is to optimize winglet geometry by using CFD with Genetic Algorithm and study its effects on power production. For validation and as a baseline rotor, the NREL Phase VI wind turbine rotor blade is used. The Reynolds-Averaged Navier-Stokes equations are solved and different turbulence models including the Spalart-Allmaras, k-epsilon Launder-Sharma, k-epsilon Yang-Shih and SST k-omega models are used and tested. The results of the power curve and the pressure distribution at dif...
Investigation and optimization of winglets for hawt rotor blades Elfarra, Monier A.; Akmandor, I. Sinan; Sezer Uzol, Nilay (2011-01-01) The main purpose of this paper is to optimize winglet geometry by using CFD with Genetic Algorithm and study its effects on power production. For validation and as a baseline rotor, the NREL Phase VI wind turbine rotor blade is used. The Reynolds-Averaged Navier-Stokes equations are solved and different turbulence models including the Spalart-Allmaras, k-e Launder-Sharma, k-e Yang-Shih and SST k-ω models are used and tested. The results of the power curve and the pressure distribution at different spanwise ...
INVESTIGATION AND MODIFICATION OF HYDROKINETIC SAVONIUS TURBINE FOR LOW WATER SPEEDS Ike-Offiah , Chiedozie Augustine; Orang, Ali Atashbar; Oğuz, Elif; Sustainable Environment and Energy Systems (2022-11) With the ever-growing global interest in reducing greenhouse gases such as CO2, renewable energy options present a good energy alternative. Not only are they a sustainable option in their operational period, but they also have a low implementation cost especially, when compared to conventional fossil fuel sources. Hydrokinetic turbines have the advantages of energy predictability, relatively low visual impact, a high energy density, high capacity factor, and ease of manufacture, in addition to the low cost ...
Investigation of bit hydraulics for gasified drilling fluids Doğan, Hüseyin Ali; Özbayoğlu, Mehmet Evren; Department of Petroleum and Natural Gas Engineering (2004) Accurate determination of the pressure losses at the bit is very important for drilling practices in petroleum industry. In the literature, there are several studies on determination of the pressure losses. Major focus is concentrated on single phase drilling fluids, which is far from accurate estimation of pressure losses for multiphase fluids, i.e., fluids including a liquid and a gas phase, at the bit. Some of these models are valid for multiphase fluids, however, they are either valid for very high gas ...
