Abstract: In the paper, an improvement λ-type scheme is proposed based on characteristics idea in order to overcome the strong dispersive effect or nonlinear instability of the original λ-scheme. Furthermore, the numerical simulations of two models of ID computational fluid dynamics problems by using the improvement scheme are given, and the numerical results are satisfactory.

Key words: λ-scheme, characteristics, numerical simulation
