Creating an accurate method to simulate unsteady incompressible flows using a simple grid system

What is it about?

In simulations that resolve fine details of turbulent flows, it is important to use accurate methods to avoid errors. A new method called HCDS6 has been developed for simulating incompressible flows on simple grids. This method is more accurate and easier to implement than standard methods, especially around complex shapes. Tests using a software called REEF3D show that HCDS6 performs well in different flow scenarios, making it a good option for efficient simulations of turbulent flows.

Why is it important?

This research introduces a new method, called HCDS6, for improving the accuracy of fluid flow simulations. The HCDS6 method is special because it is both more accurate than the standard method and easier to use than other advanced methods. It works well on complex shapes and grids without producing extra errors, making it a good option for detailed fluid simulations.
