Abstract
A report is given of some studies of adiabatic flashing flow of water in tubes; it forms an extension of the work reported in reference (1). The work, which is supported by a grant from the Science Research Council, is part of a programme of research directed towards the flash distillation process. The principal phenomena governing this type of flow are discussed, including, in particular, the local rate of formation of vapour, because it is this which determines the non-equilibrium character of flashing flow. Equations are developed to describe the problem, and numerical solutions are compared with experimental results. Experimental technique is discussed, including the measurement of density by a ‘one-shot’ gamma-ray method.
