摘要 提出了同时考虑浊度和池底漫反射的太阳池辐射透射模型和热效率模型,计算分析了浊度和池底反射 率对太阳池热性能的综合影响。模拟计算表明,浊度一定时,热性能总是随着池底反射率的增大而降低。计算 还表明,存在一个临界池底反射率,当池底反射率小于临界值时,浊度的增大导致太阳池热性能的下降;当池 底反射率超过临界值时,一定范围内浊度的增加反而有利于太阳池热性能的提高;当池底反射率在临界值附近 时,浊度的变化对太阳池热性能的影响很小。通过模拟计算得出了典型情况下的临界池底反射率,在太阳池的 实际研究和设计中可供参考。 Taking into account the water turbidity and diffusive bottom reflection, a radiation transmission model and a thermal efficiency model for the solar pond were put forward. The combined effect of the water turbidity and bottom reflectivity on the thermal performance of the solar pond was analyzed by means of numerical simulation. The thermal performance of the solar pond decreases with increasing the bottom reflectivity when the water turbidity is constant. There exists a critical value for the bottom reflec...
