A report presents a computational study of heat and mass transfer for isolated and interacting drops of one fluid (liquid O2) immersed in another fluid (H2) in finite, quiescent surroundings under supercritical conditions. The mathematical models used in this study were described in three previous articles in NASA Tech Briefs; namely, "Model of a Drop of O2Surrounded by H2 at High Pressure" (NPO-20220), "The Lewis Number Under Supercritical Conditions" (NPO-20256), and "Model of Interacting O2Drops Surrounded by H2 at High Pressure" (NPO-20257), Vol. 23, No. 3 (March 1999), page 70.

This work was done by Josette Bellan and Kenneth Harstad of Caltech forNASA's Jet Propulsion Laboratory. NPO-20404
