摘要：
Operating modes with normal and degraded heat transfer (the latter with peaks of wall temperature) during turbulent flow of carbon dioxide in a round tube at supercritical pressure are calculated. The calculated results are compared with experimental data on the wall temperature, pressure drop, and friction obtained under the conditions of a weak effect of thermogravitation. An explanation for the specific features of convective heat transfer in the region of supercritical pressures is given. © 2012 Pleiades Publishing, Ltd.
