Abstract: This paper gives an approach to expanding the nonconservation viscous vector equations in non-orthogonal curvilinear coordinates. In the expansion expression the number of terms included is greatly decreased, so the method can be easily used in engineering calculation. Numerical results of 2-dimension calculations in plane blade grid and in pressure-amplied pipe indicate the new approach of expansion very useful in practice.

Key words: internal fluid field, blade grid, numerical calculation
