Finite volume method for simulation of flowing fluid via OpenFOAM

This article explains the non-Newtonian fluid simulations via OpenFOAM. The non-NewtonianIcoFoam solver is used for the simulation of the non-Newtonian fluid flow. High-resolution mesh is used for the simulation of flow around the cylinder. The article focuses on the implementation and functionality of the code of the non-Newtonian power law equations. Some basic information about OpenFOAM is also presented in the manuscript. The method used in the analysis for the simulation of the problem in the article is finite volume method (FVM). The simulations of the problem are demonstrated via graphs and animated videos. The flow analysis made by OpenFOAM states the behavior of velocity field when the fluid hits the obstacle. The animated videos further include the behavior of velocity in the leaving zone of cylinder obstacle. The clear view of fluid flow can be seen far from the cylindrical object. Graphic abstract
