This project applies new, efficient, algorithms to computer codes that will describe the complicated details of trasonicflow in engine intakes and nozzles. the emphasis is on the ability of the codes to describe unsteady effects. great accuracy is provided by a second-order integration… More

We propose to write codes for a fast evaluation of steady, compressible, two-dimensional, inviscid flows, either subsonic or transonic, with or without bow shocks and imbedded shocks. the computational speed will be provided by a novel sweeping technique, based on the "lambda" integration scheme.… More

The computational technique for two-dimensional, unsteady flows which we developed (a combination of the lambda-schemeand shock-fitting) has produced excellent results and requires substantially less computational time than shock-capturing techniques. it is proposed to extend the technique to… More
