✦ Synopsis

A BS TRA C T

A nonlinear relationship between the pressure and the particle velocity at an air, fluid inte(face is derived under the assumption that propagation in the.fluid is exclusively outgoing. The derivation employs Riemann invariants. The relationship is then incorporated with the authors'existing interior scheme for nonlinear propagation (NLPP method) to allow a solution Jor a large amplitude acoustic pulse incident on a.fluid interface.

The Method of Fundamental Solution (also known as the F-Trefftz method or the singularity method) is an efficient numerical method for the solution of Laplace equation for both two-and three-dimensional problems. In recent years, the method has also been applied for the solution of Poisson equations
