User's Manual for a Fully Automatic Three-Dimensional Potential-Flow Calculation Method. Part II. With Viscous Correction by Small Crossflow Boundary-Layer Analysis.
Abstract
This report describes a computer program which calculates three-dimensional viscous effects on the lift and pressure distributions of arbitrary three-dimensional bodies. The program is a combination of a panel method, which computes the potential flow about arbitrary three-dimensional lifting configurations, and a three-dimensional boundary-layer method, which calculates the viscous effects with small crossflow. These effects are applied to the three-dimensional shape, as in Part 1, in a 'strip-theory' sense and the resultant viscous lift and pressure distributions are again produced. The method of simulating the boundary layer in the final potential-flow calculation is by the addition of the displacement thickness to the original shape. The computer program is written in Fortran IV for the IBM 370 systems. 16 temporary external units are used for storage. The region size needed to execute the program is about 360K bytes, but this is a direct function of the number of elements defining the configuration.
