A microcomputer software package, SFWS (Software for Water Sparging) Version 1.10, has been developed to analyze the sparging of water from the Melton Valley Storage Tanks (MVSTs) located at Oak Ridge National Laboratory (ORNL). SFWS is a menu-driven, user-friendly software package and does not require any previous experience with computer operating systems. The main menu is divided into four submenus consisting of: (a) evaporation of MVSTs, using thermodynamics analysis, (b) evaporation of MVSTs, using heat- and mass-transfer analyses, (c) comparison of the accuracy of this software against the experimental setup at ORNL, and (d) exit. The analysis is carried out based on the mathematical modeling of bubble formation, velocity of rise, and the Nusselt and Sherwood correlation obtained and used for heat- and mass-transfer analysis of gas/liquid two-phase flow (Perry & Green, 1984). The software is developed for the IBM or IBM compatible personal computer and is written in the GW-BASIC language.
