Effect of gas entrainment on the heat transfer characteristics of mercury under turbulent flow conditions : final report /

"Gas entrainment, indicated by visual bubbles in the mercury, led to low heat transfer rates which were increased by increasing the static pressure. Suitable changes in the flow system resulted in a reduction of this entrainment effect and an increase in heat transfer performance."--Page iii.
