The measured heat transfer coefficients and numerical simulation of temperature rise change in superheated water bodies
In the design phase of a coastal power plant,numerical simulation is usually used to predict the influence scope of thermal water discharge needing the realistic heat transfer coefficients.The coef-ficient was almost judged based on experience and lack of systematic research actually so far.To solve this problem,this paper analyzed the comprehensive heat dissipation of the Meizhou bay power plant,and proposed a method for measuring the coefficients.The measured data showed that heat transfer co-efficients fluctuated dramatically during high and low tides,so the empirical constant was not complete-ly reliable with deviation.Conversely,the model results could reflect the temperature rise change more accurately caused by external factors,which was more consistent with the measured.This simulation method increased the accuracy of the heat transfer coefficients,and it had an important progress in ra-tionally determining the influence of thermal water drainage.
