摘要
对斜坡太阳能热气流发电系统进行数学建模,并根据数学模型编制相关的计算程序。在改变烟囱高度和改变热流密度两种工况下进行数值模拟,计算结果表明:随着烟囱高度的增大,集热棚出口风速逐渐增大、空气温度逐步降低;随着热流密度的增大,集热棚出口风速、温度逐渐增大。通过该模型的数值计算结果与实验测量值有较好吻合度,验证了该模拟方法的正确性。
A mathematical model was established of the slope solar chimney power plant system. A procedure was built according to mathematical model to calculate the theoretical performance of the system. Influence of the chimney height and heat flux was carried on. Simulation results indicate that the speed of fluid was increased and the temperature of the fluid was reduced when raise the height of chimney; the speed and temperature of the fluid were increased when enhance the heat flux. The research shows that an excellent consist both with numerical simulation and the practical testing methods, further more, the mode is tested to be validity.
