Abstract
The Kelvin–Helmholtz stability of the cylindrical interface between the vapor and liquid phases of a fluid is studied when the vapor is hotter than the liquid and the two phases are enclosed between two cylindrical surfaces coaxial with the interface, and when there is a mass and heat transfer across the interface. Both axisymmetric and asymmetric disturbances are considered. A comparison of the results obtained here with those for the corresponding problem with plane geometry reveals that the plane geometry configuration is more stable than the cylindrical one, and, contrary to the case of Rayleigh–Taylor instability problem, the heat and mass transfer has a destabilizing influence on the system.
