| Popis: | A three-dimensional Euler code, previously developed for high-speed propellers, was rewritten and vectorized for the Cray computer. First-order accurate, implicit integration was combined with approximate factorization, central differences, and constant coefficient dissipation to solve the unsteady, compressible Euler equations in general curvilinear coordinates. Calculations were compared with previous results and measurements. The new code required less memory and was more than two times faster than its predecessor. New boundary conditions produced more accurate results in terms of integrated performance characteristics. The code is a useful tool for examining the fluid dynamics and performance of propellers. |
