摘要
提出了一种改进的泡露点的计算方法。新方法使用线性化的目标函数、Newton—Raphson法和弦截法相结合的迭代方法 ,并且通过理想系统气液平衡关系来估算初值。与弦截法、函数转换法进行计算比较 ,结果表明该方法具有迭代时间短、迭代次数少的优点 ,一般只需要 1～
In this paper a modified method for calcalation of the bubble point and the dew point is proposed,By using the linearization object function and the iteration which combined with the Newton method and secant method the initial value is estimated with the gas -liquid equilibrium of ideal system.Compared with the secant method and function conversion method,the result show that the method converges more rapidly.Generally,it will converge after iterating 1～2 times.
