Extensive Verification of the Denton New Scheme From the User’s Point of View: Part I—Calibration of Code Control Variables

Abstract

Recently, a computer-aided interactive design system has been used for turbine design. The blade-to-blade flow program incorporated in the system is required to have short run times, robustness, and no limitations. The Denton time-marching code is attractive as it is fast and can handle mixed subsonic–supersonic flows. The Denton new scheme was published in 1982 and improvements were achieved in run times and entropy conservation. In this paper, code control variables are calibrated from the user’s point of view. Factors affecting computing costs and accuracy are investigated, and the “know-how” necessary to operate the code efficiently is discussed. Comparisons of calculated and experimental results are presented in part II.
