This paper exploits blade surface pressure data acquired by testing a three-bladed upwind turbine operating in the field. Data were collected for a rotor blade at spanwise 0.7R with the rotor disc at zero yaw. Then, for the same blade, surface pressure data were acquired by testing in a wind tunnel. Analyses compared aerodynamic forces and surface pressure distributions under field conditions against analogous baseline data acquired from the wind tunnel data. The results show that aerodynamic performance of the section 70%, for local angle of attack below static stall, is similar for free stream and wind tunnel conditions and resemblances those commonly observed on two-dimensional aerofoils near stall. For post-stall flow, it is presumed that the exhibited differences are attributes of the differences on the Reynolds numbers at which the experiments were conducted.

Fluent Software

On the premise of the simulation data for the inner fuild passing the elbow pipe by means of software named FLUENT and dimensional analysis, the formula modle of inner surface pressure for elbow pipes came up by analyzing the relationships among the inner surface pressure P ,the fluid outlet pressure P0 ,axial angle α, circular angle β and the degree of curvature k; Depending on the inner surface pressure data simulated under 150 kinds of conditions, the pressure formula was fitted by means of 1stOpt software; The verification results show that the calculated value by the formula matched with the value of simulation by FLUENT software very well, the maximum relative error was 0.004%, and the research conclusion layed the theoretical groundwork for the design of the high pressure and high velocity elbow.

Typical Test

In order to assist in the understanding of high speed flutter, a series of tests has been conducted on a research fan in which the blade surface pressures have been measured by means of miniature silicon diaphragm pressure transducers embedded in selected fan blades. Prior to this investigation a program of rig tests was conducted to examine the effects of centrifugal force and vibration on the transducer performance and a transducer mounting technique was developed to minimize blade induced stress in the transducer. Instantaneous measurements of the tip stagger angles of the pressure instrumented fan blades have enabled a cross correlation to be performed on the blade surface pressure data and the blade tip angles. Some typical test results are shown.
