The approximational solution is decomposed into large and small eddy components. The high-precision solver is used to obtain the large eddy components and the low-precision solver is used to obtain the small eddy components since that the small eddy components carry a little part of the total energy. Numerical tests present the efficiency of the mixed-precision method.

This paper presents different methods for generating clouds of points around objects for use with meshless methods in computational fluid dynamics. This image shows the cloud generated around the original ROBIN body.

A cavitation implementation algorithm is developed using a pressure-based method for incompressible flows with three-phase interactions, which involve high Reynolds number multi-phase turbulent flows interacting with moving bodies of complex geometries.

An extended height function method for 3D VOF simulations applicable to the wetting phenomena on super-hydrophilic and super-hydrophobic surfaces is proposed. By implementing specific treatments of contact line identification and height function construction, reflecting the contact angle boundary condition, the proposed method ensures the first- or second-order convergence of the curvature at the contact line for a wide range of contact angles. Additionally, droplet spreading driven by surface tension on solid walls can be reproduced.
