Numerical computation of full three-dimensional flow in transonic turbines
Abstract
The scalar integral form of momentum equations in the cylindrical coordinate system is derived by a simple method. The derived equations can be applied to an arbitrary control volume. It is shown that all radial momentum equations are missing a term. The influence of the missing term on computational results is discussed using a numerical test. It is also shown that the discrete form of the radial momentum equation has a wrong sign and cannot be applied to an arbitrary control volume.
