A tentative method for the rapid calculation of the pressure drop during forced-circulation boiling of water is presented. The method is based upon the application of pressure-drop data, obtained during the isothermal flow of air and various liquids, to the evaluation of local pressure gradients during forced-circulation boiling. Curves are developed by means of which the pressure drop during boiling can be estimated quickly once the exit quality, the boiling pressure, and the pressure drop for 100 per cent liquid are known. The proposed method is definitely an extrapolation of existing data and, as such, requires further experimental verification. |
