RÉSUMÉ

Enhancement of heat transfer due to slug bubbles passing through a capillary channel submerged into liquid is considered. A model of hydrodynamics is proposed describing the influence of the entrance region of the rectangular channel. Different regimes of heat transfer depending on fourth time-values of process: τ0, tc = Lc/Ub, t* = y*/Ul, tb = V/(UbS) are determined. A physical model of heat transfer takes to account the influence of liquid velocity, nonstationary effect of bubbles passing near heater and predominantly influence of the thermal layer forming on the low part of the heater. The calculation from this model is shown to provide agreement with experimental data.
