Users manual for a fully automatic threedimensional potentialflow calculation method. Part 2: With viscous correction by small crossflow boundarylayer analysis
Abstract
This report describes a computer program which calculates threedimensional viscous effects on the lift and pressure distributions of arbitrary threedimensional bodies. The program is a combination of a panel method, which computes the potential flow about arbitrary threedimensional lifting configurations, and a threedimensional boundarylayer method, which calculates the viscous effects with small crossflow. These effects are applied to the threedimensional shape, as in Part 1, in a 'striptheory' sense and the resultant viscous lift and pressure distributions are again produced. The method of simulating the boundary layer in the final potentialflow 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.
