In the present paper, the results of the Artificial Compressibility version of the Characteristic Based Split algorithm (AC-CBS) are analysed for both forced and natural convection incompressible flows. A dual time-stepping procedure is used to recover the real transient solution. The true transient term is discretized explicitly up to the fourth order of approximation, allowing the adoption of larger true time steps, and resulting in a more robust and efficient algorithm.

Abstract
In the present paper, the results of the Artificial Compressibility version of the Characteristic Based Split algorithm (AC-CBS) are analysed for both forced and natural convection incompressible flows. A dual time-stepping procedure is used to recover the real transient solution. The true transient term is discretized explicitly up to the fourth order of approximation, allowing the adoption of larger true time steps, and resulting in a more robust and efficient algorithm.File in questo prodotto:
