摘要:
本文基于准一维流动模型运用近代变分法研究了磁流体发电通道的无约束最优化问题。文中以给定通道入口滞止焓和背压为端点条件,从长度给定的通道中抽取最大电功率为性能指标,运用本文所提出的最优化算法进行了小型法拉第型通道的最优化计算。得出了超音速通道为最优,在最优解附近输出电功率对通道型线的变化不太敏感等结论。本文还计算了磁场、壁温、背压、等截面段长度等参数的变化对最优通道性能的影响。文中采用的数学模型所考虑的因素比较全面,除了考虑化学反应、摩擦、散热之外,还考虑了边界层、漏电、电极电阻和有限分段等因素的影响。
Abstract:
This paper studied unconstrained optimization of MHD generator duct on the basis of quasi-one-dimensional model using the modern calculus of variations. The optimization procedure proposed was then applied to the design of a small segmented-electrode Faraday MHD duct. It is desired to maximize the electrical power output extracted from the duct of a given length under the terminal conditions of given inlet stagnation enthalpy and back pressure. It was concluded that the supersonic duct is optimal and its electrical power output is not sensitive to the variations of the duct shape around the optimal one. The effect of parameters, such as magnetic field, wall temperature, back pressure, length of the section with constant cross-section attached to the generator duct outlet, etc. , on the performance of the optimal duct was also calculated. More factors were considered in the model used. Besides friction, heat loss and chemical reaction, the factors, such as boundary layer, currct leakage, electrode resistance and finite segment of electrodes, were considered.
