Description
Summary:Results of calculation of the efficiency of porous direct-flow steam-generating channels in the transition region of motion of a heat-transfer agent with boundary conditions of the first kind have been presented. The obtained data have been compared with the results of calculations for a smooth-walled tube. It has been shown that positive values of geometric coefficients of efficiency of such a channel can be obtained when water is used as the heat-transfer agent. For the investigated parametric range of the indicated channels, no positive values of energy coefficients of efficiency were found. The dependences of the efficiency coefficients of a porous model channel on its basic operating-structural parameters have been analyzed.
