MUMERICAL COMPUTATION OF FLOW AROUND AEROSTATS USING A PRESSURE-BASED NAVIER STOKES SOL VER

摘要

An implicit finite volume algorithm based on numerical solution of Reynolds Averaged Navier Stokes (RANS) equations, is presented for prediction of turbulent flow around aerostat Structures with appendages. The algorithm employs a pressure-velocity solution strategy, Non-orthogonal body-fitted grids, collocated variable arrangement coupled to the low-diffu- Sive upwind schemes for convective flux discretisation and the eddy-viscosity based standard k-ε turbulence model for simulation of the turbulence effects.
