CRITICAL HEAT LOAD IN FORCED CONVECTION OF MONOISOPROPYLBIPHENYL IN TUBES AND DUCTS

Results are given from experimental studies of critical heat loads in forced monoisopropylbiphenyl flow. The critical heat load for 6 to 8 mm ducts varied from 3.7 to 4.8 x 10/sup 6/ kcal/m/sup 2/.h with a 6.3 m/sec flow rate and 124 to 190 deg C underheating and from 2.7 to 3.8 x 10/sup 6/ kcal/m/sup 2/. h with 120 to 195 deg C underheating. Flow rates in 10-mm diameter, 150-mm long tubes were 4 and 8 m/sec with underheating from 0 to 194 deg C. The results for these conditions are tabulated and analyzed. (R.V.J.)
