摘要

The present paper gives the introductive description of a new method of derivatioon and expression by the authors for the conservation from of fluid dynamic equations in curvilinear coordinate systes.As different to the usually used mehtod based on the corrdinate transformation,our mehtod is rid of the dependence on Cartesian coordinates and overcomes the difficulty that either arbitrary components fo velocity cannot be adopted or the ocnservation cannot be riegorously presenved.Example equations are taken to demonstrate the flexible applications of this general and universal mehtod to the cases of various corrdinates and velocity components.Computational examples show that the method is quite suitable to turbomachinery.
