Computational Modeling of Blade’s Impact on the Hole Cleaning Device’s Decaying Swirl Flow

Abstract

This work presents the Decaying swirl flow behaviors of turbulent flow in active mixer through a numerical examination and analysis. The numerical analysis was carried out by solving the 2D Navier-Stokes equations for new dynamic mesh tecnic, using the computational fluid dynamic (CFD) tool . The computation of the hydrodynamic and swirl flow efficiency yields an estimated index for various scenarios, the tangential velocity distribution, and the variation of pressure are analyzed. When it comes to hole cleaning, the swirl flow will be nearly parallel to the radial flow. Moreover, as the blades rises above the critical threshold, the swirl flow's rotational direction will alter.
