Development of a finite volume code for spatially evolving simulations of flow past wings We have developed a three-dimensional finite volume code for performing simulations of spatially evolving flows. The finite volume technique is preferred due to its flexibility for implementing a variety of realistic and physically relevant boundary conditions e.g. unlike spectral codes this method is not constrained to periodic boundary conditions only and therefore allows simulations of flows past wings with finite spans. The algorithm is formulated with equations written in generalized coordinates which makes this code useful for simulating a wide variety of flows including spatially evolving jets, flows past bluff bodies of different geometries. etc. Also, versatile grid-generation is useful in compressible flows for local grid refinement to resolve shocks.
