海岸TIBL的数值模拟──E─ε闭合模式的应用

NUMERICAL SIMULATION OF THE TIBL IN COASTAL AREAS-APPLICATION OF E-ε CLOSURE MODEL

利用二维的非线性ＰＢＬ方程组，采用工程上常用的Ｅ－ε闭合方法模拟了海岸地区热力内边界层的形成和发展过程中的背景个均风、温场以及湍流场的特征。

he two-dimension mesoscale planetary boundary layer model with a simple E-ε closure scheme, which has been used mostly in the field of engineering, is used to simulate the evolution of the thermal internal boundary layer (TIBL) in coastal areas and study the characters of wind, temperature and turbulence fields in the course of TIBL development. The result obtained from this model agrees with that from other models and observation data.
