Type of article: Article

Summary

IN VERTICAL GAS-LOADED TWO-PHASE REFLUX THERMOSIPHONS, THE TEMPERATURE AND CONCENTRATION GRADIENTS, BETWEEN THE ACTIVE AND SHUT-OFF REGIONS CAN CREATE DOUBLE-DIFFUSIVE MIXED CONVECTION FLOWS. WHEN THE NONCONDENSABLE GAS MOLECULAR WEIGHT IS GREATER THAN THAT OF THE VAPOUR, DIFFERENT STEADY AND TIME-DEPENDENT GAS RECIRCULATION PATTERNS DEVELOP, SIMILAR TO THOSE OBSERVED DURING RAYLEIGH-BENARD CONVECTION INVRAO EXPERIMENTAL RESULTS PRESENTED SHOW THAT BIFURCATIONS FROM AXISYMMETRIC TO THREE-DIMENSIONAL, THEN ASYMMETRIC, AND FINALLY MULTIPLE DISTINCT GAS-FLOW PATTERNS OCCURS AS THE RAYLEIGH NUMBER INCREASES.
