A summary is given of the work carried out over the past few years in the field of experimental boiling fluid flow. The various apparatus tested are described, along with pertinent variables investigated in each test. The tests described cover natural circulation boiling at pressures up to 600 psia, and power densities up to 95 kw/liter. Both steam-water densities and steamwater friction factors, for boiling with uniform heat addition, were studied. Also included are: (1) a brief description of boiling instability tests using electrically heated elements; and (2) a summary of visual studies using air-water mixtures at atmospheric pressure. Design equations, and hydrodynamic and heat transfer design criteria for natural circulation boiling reactors are presented. Included are methods for calculating steam volume fractions and recirculating flow rates as functions of reactor power. Heat transfer equations are listed, compared, and discussed. Burnout limitations are discussed. The method for calculating recirculating natural circulation boiling reactors is based on modifications of the standard equations for single-phase flow. (auth)
