“…At high Reynolds number, explicit schemes such as the popular MacCormack algorithm [7] have very restrictive stability properties associated with the CFL time step limit and the fine mesh near blade boundaries. In principle, we can resolve this stability problem by using an implicit algorithm like the Beam-Warming or Eriley-MacDonald schemes [8,9].…”

The present paper describes a computer code, currently under development, aimed at solving the equations of three-dimensional viscous compressible flow in turbomachinery goemetries. The code uses a simple, novel pre-processed implicit algorithm. An outline of the method is given and the current capabilities of the code are assessed. The code is applied to the study of the flowfield in a cascade of transonic gas turbine rotor blades. The geometry and the presence of inlet end-wall boundary layers lead to significant three-dimensional effects. The pattern of secondary flow development, including the details of the leading edge horseshoe vortex and associated saddle point, are clearly resolved and correspond to experimental experience. A computation is also presented to show the influence of dihedral (non-linear stacking) on the secondary flow development.
