Detached-Eddy Simulation of Normal Flow past Flat Plates: The Influence from Corner Curvature

Research output: Contribution to journal › Journal article › Research › peer-review

Abstract

Normal flow past flat plates at high Reynolds numbers appears in various engineering contexts. To accurately model such flows for slender plates in Computational Fluid Dynamics requires scale-resolving rather than scale-modeling methods. The present paper uses Detached-Eddy Simulation to investigate the influence of plate corner curvature on global flow quantities such as the time-averaged drag coefficient. The effect of corner curvature is mapped and collated with the literature. Solution verification is carried out to quantify the numerical uncertainty. The time-averaged drag coefficient increases significantly between semi-cylindrically rounded (<C_D >_t = 2.28) and sharp-cornered (<C_D >_t = 2.42) plates.
