The Kelvin–Helmholtz instability of the cylindrical interface between the vapor and liquid phases of a fluid has been investigated when the vapor is hotter than the liquid and the physical model is a free-swirling annular liquid layer confined in a tube with the gas phase in the center. A stability analysis that includes the effect of swirl along with mass and heat transfer is presented. In this paper, the ratio between conduction heat flux and evaporation heat flux characterizes the heat transfer at the interface. This work examines the effect of various nondimensional parameters on the instability of the flow. When the ratio of the conduction heat flux to the evaporation heat flux increases, the growth rate increases and the wave number remains unchanged. Although the confinement increases, the stability of the liquid varies from its condition without heat and mass transfer.
