UNILATERAL HEAT TRANSFER TO LIQUID METALS FLOWING IN CONCENTRIC ANNULI

Technical Report ·
OSTI ID:4766055
Using a Lyon type of analysis, theoretical Nusselt numbers have been calculated for liquid metals flowing in concentric annuli, under conditions of constant heat flux and fully-established turbulent flow. These have been expressed in the form of semi-empirical equations for the case of heat transfer from the inner wall only and for the case of heat transfer from the outer wall only. Predictions on the basis of these equations are compared with those by other relationships and with experimental results. The proposed equations are consistert with those for turbulent flow of liquid metals inside circular tubes and between parallel plates; the former being the limit for an annuius as r/sub 2/ /r/sub 1/ approaches infinity, and the latter being the limit as r/sub 2//r/sub 1- / approaches unity.
