Steady laminar flow in a 90° bend

Steady laminar flow in a 90° bend

This research undertook an assessment of the characteristics of laminar flow in a 90° bend. The research utilised the computational fluid dynamics software tool ANSYS Fluent, adopting a finite volume method. The study focused on pressure decreases, velocity profiles, Dean vortices and Dean cells pre...

The study focused on pressure decreases, velocity profiles, Dean vortices and Dean cells present in the bend.
