A note on a derivative scheme for the finite volume method applied to incompressible viscous fluid

In the last two decades, there have been significant advances in application of the finite volume method to a wide spectrum of physical phenomena, ranging from heat transfer and compressible/incompressible fluid flow to solid mechanics. The finite volume method requires for different applications similar approximations of derivatives at the control surface. Within this framework, this study discusses a derivative scheme used in the finite volume method for incompressible viscous fluids. The numerical scheme is based on an implicit technique associated with the SIMPLE method to attain pressure–velocity coupling. The present work addresses simulation of two-dimensional flows in plane channels with and without contractions. The results show velocities and pressure fields with good agreement when compared to analytical results.
