Pressure distribution on propeller blade surface using numerical lifting surface theory

Abstract

Block 20 continued) PSP are compared with selected experimental values that are believed to be accurately and reliably measured. Comparisons are also made between PSP predictions and other theoretical predictions. The predictions by PSP are generally in good agreement with experimental values and with other prediction methods except for the tip region where current procedures may not be accurate enough to represent the actual flow.

“…A typical chordwise pressure distribution for a section of a ship propeller obtained by Hess & Yalarezo (1985) is shown in Figure 14, together with results computed by Kim & Kobayashi (1984) and measurements Versmissen & van Gent (1983). Kim & Kobayashi's results were obtained from their extension of the PSF-2 vortex-lattice program to include the Figure 13 Illust~'ation of propeller blade and hub panelling.…”

“…The solid line (identified as PRESENT METHOD) was obtained by Hess & Valarezo (1985) using their surface-panel code. The dashed line (identified as PSP METHOD) was obtained by Kim & Kobayashi (1984) using a vortex-lattice method based on PSF-2. The two experimental curves were obtained by Versmissen & van Gent (1983) using pressure transducers embedded in a 0.48-m diameter propeller model.…”
