A Method for Calculating Crossflow Separation Patterns on Submarine Hull/Sail Configurations
1991
Abstract : This report describes a method and a computer program for calculating the crossflow separation patterns on submarine hull/sail configurations. The method is based on inviscid flow solutions provided by a panel method and on solutions of the three-dimensional boundary-layer equations which incorporate the Cebeci-Smith eddy-viscosity formulation. The computer program embodies these two methods and an interface method with user friendly input and output subroutines. Calculated results are reported for submarine hull and submarine hull/sail configurations at incidence angles of 10 and 15 degrees and show that this numerical scheme, with its stability requirements, provides an efficient and accurate means of predicting crossflow separation patterns. A typical calculation time is around 30 seconds on a CRAY-2 computer for a submarine hull/sail configuration.
