摘要
The mathematical model of turbulent buoyant recirculating flows is applied in thermohydraulics and an algebraic stress model is proposed to simulate noniso- tropic turbulent buoyant recirculating flows in a shallow water channel.It can be shown that the buoyancy force is able to reduce the turbulence in vertical di- rection and the heat conduction in the thermocline layer is nonisotropic.At the same time,the stacked-up and separated arrangement of intake-outlet for thermal power stations have been predicted by such numerical models.The results are in good agreement with experiments(ref.1-3).
