Comparison of 2D and 3D modelling applied to single phase flow of nanofluid through corrugated channels

Nanofluid flow through non-corrugated and corrugated channels is studied using a two-dimensional (2D) and three dimensions (3D) numerical simplification. Due to the high computational costs of a full 3D grid model, the 2D approach offer a more practical advantage. However, little information a...
