Liquid/Vapor Action in a Vessel During Blowdown

Abstract

Vapor bubble rise forms the basis for a theoretical study of liquid/vapor action in a saturated system during blowdown. Methods are developed and demonstrated for predicting time and space dependent mixture properties. Graphs are presented for estimating the time-dependent mixture level during steam, water, and mixture blowdowns from 1000 psia. Theoretical mixture levels are compared with vapor blowdown experiments. Although calculations strongly depend upon bubble rise velocity in the liquid, reasonable agreement with data is shown.
