Abstract

A three-dimensional moving mesh method for solving theEuler equations describing the compressible flowabout a wing undergoing arbitrary motions anddeformations is described. A finite-volumeformulation is chosen where the volumes distort asthe wing moves or deforms. By using transfiniteinterpolation, a technique for generating therequired sequence of grids has been developed.Furthermore, as the speeds of the grid at thevertices of the finite volumes are required by theflow solver, transfinite interpolation is also usedto obtain these by interpolation of the boundaryspeeds. A two-dimensional version of the method hasalso been developed and results for both two- andthree-dimensional transonic flows are presented andcompared with experimental data where available.
