CALCULATING THE THERMOHYDRAULIC EFFICIENCY OF POROUS STEAM-GENERATING CHANNELS IN THE TRANSITION REGION OF MOTION OF A FREON 12 HEAT-TRANSFER AGENT WITH BOUNDARY CONDITIONS OF THE FIRST KIND

The author has presented results of calculating the effi ciency of porous channels during the evaporation of a vapor– liquid Freon fl ow in the transition region of motion of the heat-transfer agent and with boundary conditions of the fi rst kind. For the sake of comparison, use was made of a smooth-wall tube as the reference surface. As a result of the conducted investigations, it has been shown that with the Freon 12 heat-transfer agent, positive values of geometric and energy coeffi cients of effi ciency can be obtained. The dependences of the effi ciency coeffi cients on the basic operating-structural parameters of the model have been analyzed
