The prediction of vapor/gas volume fraction in a liquid media in a              rapidly depressuring system is a problem which arises in numerous               technical applications.  The solution requires knowledge of the number          of bubbles per unit volume of the flashing mixture, as well as the              volumes of the individual bubbles, as a function of time.                       Carefully-controlled depressurization experiments are performed in a            vertical shock tube, in which mean void fraction will be measured as a          function of time and pressure, with and without the presence of                 stainless-steel surfaces using deaerated distilled water.  The nucleus          distribution function is determined from these data by a numerical              inversion of the integral equation, or approximately by an inverse              transform procedure.  This experimental work gives information on the           effective distribution of bubble nucleii on typical engineering                 surfaces.
