This website is very useful to compute Reynold number, y+ and other parameters to define the prism layers in Simcenter STAR-CCM+ as well as OpenFOAM snappyHexMesh for external and internal flow when meshing.
-the height of the first cell in the prism layer
-boundary layer thickness

Trang web tính các tham số cần thiết khi tạo lưới và layer cho Simcenter STAR-CCM+ và OpenFOAM.
- Kích thước lớp cell đầu tiên
- Độ dày lớp biên

Use Volupe's All-Y calculator for precise meshing of geometries in your CFD analyses, ensuring accurate results.

I see this video explains SIMPLE Algorithm in simple way :). Everyone also can watch other videos on this channel.
The SIMPLE Algorithm (to solve incompressible Navier-Stokes).

Cách quan sát dòng laminar và turbulent trong mô phỏng CFD
-----------------------------------------
How to recognize difference between laminar flow and turbulent flow in CFD simulation?

What is turbulent?
1. Unpredictable: the flow is chaotic and change direction somewhere in the fluid
2. swirls on many scales: eddies or vortices span a huge range of sizes
3. Diffusive: it mixes things together
4. High Reynolds number: is result turbulent flow. Laminar flow only occurs at low Reynolds number
5. Dissipative: it takes in energy at the largest scales at these big eddies, until on the smallest scale that energy gets dissipated to the fluid as heat.

Everyone loves laminar flow but turbulent flow is the real MVP. A portion of this video was sponsored by Cottonelle. Purchase Cottonelle Flushable Wipes and ...
