Boiling at the Boundary of Two Immiscible Liquids below the Bulk Boiling Temperature of Each Component

摘要

The problem of vapor formation in the system of two immiscible liquids is considered at the tem-peratures that are lower than the bulk boiling temperature of each component and higher than the tempera-ture at which the sum of the saturated vapor pressures of the components is equal to atmospheric pressure. In this situation, boiling occurs at the surface of direct contact between the two components. The kinetics of the vapor layer at the contact boundary is theoretically described, and a solution is obtained for the idealized case where the properties of the two liquids are close to each other. The relation between the solution for the vapor layer kinetics and the integral boiling characteristics of the system is considered, and the problem of cooling the system in the absence of a heat inflow is solved.
