Numerical Investigations into the Base Drag of Various Wedges Using the Base Flow Model Developed by Mauri Tanner

摘要

The base flow model of Tanner for two-dimensional wedges is studied. The separation region is modeled to form a closed body behind the wedge. The flow past the wedge and the separation region, the form of which is systematically varied, is calculated using potential flow theory. Three wedges are studied: 5, 30 and 60 degrees. The potential flow is calculated using a low-order panel method. For the 60-degree wedge, results are compared with experiments.
