The present paper focuses on some details of the general solver for N-S equation with an unstructured finite volume method. The general equation was discrete term by term and the general boundary dealing methods are also given out. A data structure and sparse matrix storage method are introduced which are easy to design a computer program and locally refine the grid. A test case is done and a good agreement of the result commercial software Fluent is achieved. A research is done with several different linear equation solvers, and the result shows that the algebraic multi-grid is better than the conjugate gradient method.
