Shock-fitting for Full Potential Equation

Pages : 44
Book Description
In this report a procedure is considered for fitting shock waves in transonic type-dependent finite-difference relaxation calculations by using the full potential equation. The iterative line relaxation method for transonic finite-difference (rotated or conservative schemes) calculations can be described by a time-dependent equation. The shock-fitting algorithm presented here depends on this unsteady equation. Written in conservative form, the jump condition is derived in terms of shock speed. In the steady-state limit, shock speed vanishes, and the steady shock polar is retained. In this way the jump conditions are imposed iteratively and in a manner consistent with the relaxation procedure that is used everywhere else in the flow field. Preliminary results for axisymmetric flows around a sphere are presented. Application of the algorithm to small-disturbance calculations are discussed in the appendix. (Author).

Book Description
The series of volumes to which this book belongs honors contributors who have made a major impact in computational fluid dynamics. This fourth volume in the series is dedicated to David Caughey on the occasion of his 60th birthday. The first volume was published in 1994 and was dedicated to Prof Antony Jameson. The second, dedicated to Earl Murman, was published in 1998. The third volume was dedicated to Robert MacCormack in 2002.Written by leading researchers from academia, government laboratories, and industry, the contributions in this volume present descriptions of the latest developments in techniques for numerical analysis of fluid flow problems, as well as applications to important problems in industry.
