Simulation of flow through a pipe using OpenFoam

Objective: The objective of this exercise is to be able to accurately simulate incompressible laminar flow through a pipe. Comparing 2 different types of boundaries in OpenFoam, symmetry and wedge. PART 1 Methodology: The domain chosen will make the exercise computationally very taxing, hence symmetry boundary condition…
