Computational study of incompressible turbulent flows with method of characteristics

作者：

Highlights：

• We developed a new characteristic-based scheme for incompressible turbulent flows.

• The Navier–Stokes partial differential equations were solved numerically.

• Numerical tests were conducted to flow past a circular cylinder.

• High stability range was achieved which led to fast convergence.

• Accurate results were obtained by applying the new CB method.
