摘要
采用曲线拟合的计算方法,拟合了一组与本计算有关的水和水蒸气热物性参数(比容、焓和熵)的经验公式,从而整理出汽轮机相对内效率的一种简化计算方法。
In this paper, a group of empiric formulae for ordinary water and steam parameters(enthalpy, specific volume, entropy isentropic enthalpy drop, and exhaust enthalpy) is given and a simplified method to calculate the relative internal efficiency (high-, intermediate-, and low-pressure cylinder)of steam turbine is introduced.
