AN EXPERIMENTAL INVESTIGATION OF FORCED CONVECTION BURNOUT IN HIGH PRESSURE WATER PART IV, LARGE DIAMETER TUBES AT ABOUT 1600 P. S. I.

摘要

The report presents 727 burnout results for tubes with uniform and non-uniform axial heat flux profiles. Most of the data are at 1600 p.s.i. although there are a limited number at 1250 and 1800 p.s.i. Tube diameters ranged from 0.5 to 1.8 inches. A new correlation for uniform flux data at these pressures is presented, having R.M.S. errors between 4 and 6％. A table of constant terms for this new uniform flux correlation is given, together with Macbeth's values for pressures of 560, 1000 and 2000 p.s.i.nExperimental and predicted burnout powers for non-uniform axial heat fluxes are compared and the existing methods of prediction are found to be in error by up to 20$. A new method for predicting burnout with non-uniform axial heat flux is developed which correlates all published data to an R.M.S. error of 6.7％.
