Later, in , Gray used data from other researchers to expand his empirical correlation of airfoil drag rise due to ice accretion for an arbitrary airfoil [16].File Size: 2MB. In this chapter we choose standard airfoil NACA Which is symmetrical airfoil with a 15% thickness to chord ratio was analyzed on ANSYS FLUENT to determine the coefficient of lift, coefficient of drag and graph of coefficient of lift vs. coefficient of drag. The 2-dimensional cross sectional view was considered.

    Design and Experimental Results for the S Airfoil Dan M. Somers t March Abstract A percent-thick, laminar-flow airfoil, the S, for horizontal-axis wind-turbine applications, has been designed and analyzed theoretically and verified experimentally in the low-turbulence wind tunnel of . Two airfoil sections, NACA and NACA , of cm chord length (i.e., leading to trailing edge dimension) were shaped from curved laminated Lauan blanks which had the grain oriented along the blade arc.
