ABSTRACT The positive effects of passive flow control on the blade that uses various methods aerodynamic performances horizontal axis wind turbines (HAWTs) are well‐known. In current study, splits were made for stall control. A numerical study using computational fluid dynamics (CFD) modeling was conducted to investigate split impacts HAWT blades. blades designed NREL's S819 profile at root section and NACA 63‐415 middle tip sections. Chord length angle attack determined by element momentum...
Experimental studies were conducted to reveal the heat transfermechanism of impacting water mist on high-temperature surfaces. A numerical model was developed simulate, for atmospheric applications, air and spray cooling surfaces heated temperatures ranging from nucleate film boiling. Local transfer coefficients measured in film-boiling regime at various velocities liquid mass fluxes. The test conditions cover variations velocity 0 50.3 m/s, flux 7.67 kg/m2s, surface temperature stainless...
Wind turbines without pitch control are more preferable from economical point of view but aerodynamic stall affects them and after a critical wind speed local boundary layer separation occurs. Consequently, their power production is relatively low. In this study, air ducts added on the blade using airflow kinetic energy low-momentum fluid behind surface was increased delay examined The Response Surface Optimization method utilized in order to get best possible design under constraints...
In many studies, computer-aided simulation methods are used to design vertical-axis wind turbines. Compared with conventional optimization methods, which show continuous improvement in parallel technology, provide important advantages, particularly terms of time and cost. On the one hand, a turbine is designed obtain maximum power; on other this must be able operate safely under extreme conditions. When considered from point view, computational fluid dynamic analysis first step that provides...
