In support of the Organic Moderated Reactor Experiment, forced- connection heat transfer characteristics of several polyphenyls have been investigated in a laboratory heat transfer loop. Heat transfer runs were made with dipbenyl, Santowax R (commercial mixture of terphenyl isomers), and a 2: 1 mixture of Santowax 0 (commercial ortho-terphenyll and Santowax M (commercial metaterpbenyl). The operating conditions were as follows: fluid temperatures, 480 to 770 °F; heater surface temperatures, 565 to 875 °F; fluid velocities, 5 to 25 ft/sec; heat fluxes, 40,000 to 290,000 Btu/hr-ft²; and Reynolds number, 20,000 to 300,000. Experimental heat transfer coefficients obtained at the above conditions ranged from 340 to 2740 Btu/hr-ft²- °F. The data obtained during this-study were correlated by the relationship Nu = 0.015Re^0.85P^r0.3. No heat transfer surface fouling, with Santowax R and Santowax 0-M as test fluids, was observed after extended runs at the following extreme conditions: fluid velocities: 5.5, 10, 15 ft/sec maximum heat transfer surface temperature: 985 °F.
