ABSTRACT	Finite-element analysis code to solve incompressible Navier-Stokes equations was incorporated into the κ-ε turbulence model of high Reynolds number type,and applied to flows around single- and multi-component aerofoils.Although the reoderate deflection angles,the computed pressure distributions around the aerofoils and lift coefficients as well are in good agreement with measured results.The effectiveness of the turbulence model for such complicated flows was assured from this fact.For the flows which oscillated periodically or corresponded to aerofoils at high angles of attack,however,there was less agreement between computed and measured results.To solve a large-scale linear equation system,which was necessitated by the adoption of the implicit Euler scheme,a newly developed code for the direct method was used successfully.
