-# OpenFOAM
+# OpenFOAM Tutorials Plus
+This repository contains several OpenFOAM cases and notes related to my blog [OpenFOAM Studio [in Chinese]](https://zhuanlan.zhihu.com/openfoam).
+
+Here's a brief description:
+* **linuxCheatSheet**
+
+  OpenFOAM Linux Cheat Sheet.
+
+* **flatPlate**
+
+  A simple 2D geometry is used to show the development of a turbulent boundary layer. It's an exercise of [Flow over a flat plate - YouTube](https://youtu.be/69Nna1UjICI).
+
+* **abruptContraction**
+
+  Abrupt contraction of a rectangular channel where cavitation occures. The *blockMeshDict* is written with variables. *interPhaseChangeFoam*, *pisoFoam* and  *pimpleFoam* are used.
+
+* **abruptContractionPar**
+
+  Parallel edition of abruptContraction.
+
+* **waterChannel**
+
+  Two-phase open channel flow. It's a fork  of the original interFoam tutorial *waterChannel*. The *surfaces* function is configured to generate water surfaces (namely, the isosurfaces where *alpha.water* is equal to 0.5). 
+
+Pull requests are welcome! Happy foaming!
