Convergent turbulence refinement toward irrotational vortex

Published: 28 July 2019 Publication History

Abstract

We proposed a detail refinement method to enhance the visual effect of turbulence in irrotational vortex. We restore the missing angular velocity from the particles and convert them into linear velocity to recover turbulent detail due to numerical disspation.
