N2 - An efficient segregated algorithm for fluid flow and heat transfer problems, called IDEAL, was proposed D. L. Sun et al. [11]. In addition, the IDEAL algorithm was extended to 2-D/3-D grid systems. In these IDEAL algorithms, all of the algebraic equations are solved by the alternating-direction implicit (ADI) method, called the IDEAL+ADI method. In this article, the efficient Bi-CGSTAB method is adopted instead of the ADI method to solve the algebraic equations in the IDEAL algorithm, called the IDEAL+Bi-CGSTAB method. It is found that the IDEAL+Bi-CGSTAB method is much better than the IDEAL+ADI method to solve open systems but little worse to solve closed systems.
