| Abstract: | Heat transfer film Coefficient of two-phase flow has been measured in a rising film e- vaporator with variable heat quantities and water rates.Having analysed effect factors on the film coefficient and regressed for experimental data,an empirical correlation of the film coefficient was obtained.Calculation values using the correlation agrred well with ex- perimental ones and compared with other data in the public references. |
