固定床内传热参数的估算
A METHOD FOR CALCULATPNG HEAT TRANSFER PARAMETERS IN FIXED BED
【摘要】 本文采用模拟平板弯曲变形的曲面样条函数表达温度分布函数,由此建立一种在固定床反应器内由实验数据推算传热参数的算法,并求出一个温度分布函数.线性方程组的求解采用全主元高斯消去法,目标函数的求解采用单纯形法.本方法计算结果可靠,与文献值符合良好.此法还具有算法稳定,对初值要求不高等优点.
【Abstract】 A new calculation method is developed to evaluate the heat transfer parameters based on the experimental data in the fixed bed reactor and a temperature profile function is also obtained. The surface spline function is used to express the temperature profile. The Gauss complete pivoting is adopted to solve the system of linear equations and the simplex method is introduced to calculate the objective function. The calculation results by this method accord with the literature data. Some other advantages of this method, such as good stability, wide adcptive range of initial value are discussed.
