Abstract. This chapter reviews the aerodynamic characteristics of horizontal axis wind turbines (HAWTs). While the aerodynamics of wind turbine are relatively complicated in detail, the fundamental operational principle of a HAWT is that the action of the blowing wind produces aerodynamic forces on the turbine blades to rotate them, thereby capturing the Cited by: 3. An experimental aerodynamic evaluation of three compact radial turbine builds was performed. Two rotors which were 40 to 50 percent shorter in axial length than conventional state of the art radial rotors were tested. A single nozzle design was used. One rotor was tested with the nozzle at two stagger angle settings.

The current work aims at describing the mechanisms of winglets on turbine rotors, and furthermore to determine the maximum achievable aerodynamic efficiency, defined as the mechanical power coefficient, Cp, for wind turbine rotors with winglets, using both a newly developed Free Wake Lifting Line (FWLL) method and the CFD code EllipSys3D. AbstractFor a radial turbine with vaneless volute, the inflow of turbine rotor usually has a circumferential flow distortion due to the influence of the volute tongue. The rotating blades of the rotor are exposed to harmonic aerodynamic loads caused by the distortion, which may induce rotor resonance and lead to high cycle failures (HCF).

The aerodynamic evaluation of two highly loaded compact radial turbine rotors was conducted at the NASA Lewis Research Center Small Engine Component Test Facility (SECTF).
The experimental results were used for proof-of-concept, for modeling radial inflow turbine rotors, and for providing data for code verification. Axial-flow turbines and radial-inflow turbines are the two most common types of dynamic turbines.
The flow streamlines through the blade rows of an axial-flow turbine have essentially a constant radius, whereas there is a substantial reduction in radius through the radial-inflow turbine.
2 radial-inflow turbine which will be designed, manufactured and tested as a part of the Australian Solar Thermal Research Initiative. Following the ORC cycle optimisation, there is a need for aerodynamic optimisation of the radial-inflow turbines which are almost the only choice, with the eventual competition of screw expanders.

The objectives of the program were to design, fabricate, and rig test compact radial-inflow turbines with equal or better efficiency relative to conventional designs, while having 40 percent less rotor length than current traditionally-sized radial turbines.
The rotor is the key part of the radial inflow turbine, and the performance of the radial inflow turbine is highly dependent on the rotor design. A good flow condition in the rotor is required to achieve a high performance. The h - s diagram for the radial inflow turbine is presented in by: 1.

In a radial turbine, the flow enters radially and exits either axially or radially depending on whether it is an inflow or outflow type radial turbine. The most commonly used type of radial turbine is a radial-inflow turbine, in which the working fluid flows from a larger radius to a smaller radius.
Furthermore, the optimization results indicate that using the present optimization approach the total-to-static efficiency of the optimized T radial inflow turbine can be increased by % under design condition and the rotor weight can be decreased by kg (%) as compared with that of the original case.
