HEAT TRANSFER AND POWER EXPENDITURE FOR AGITATED VESSELS HAVING BARE AND FINNED, VERTICAL TUBE BAFFLES
Abstract
Heat transfer and power expenditure results have been obtained for an agitated vessel equipped with bare tube, low finned-tube, and medium finned-tube, vertical tube baffles. The mixing vessel was 45.7 cm (18 in.) in diameter, filled to a fluid depth of 91.4 cm (36 in.), and contained four vertical tube baffles. Agitation was provided by a dual impeller, 15.2 cm (6 in.) diameter, six-blade, flat blade turbine. Both heating and cooling data were obtained using water, ethylene glycol, Mobil-therm 600, and Gulf Harmony 151, as test fluids. Heat transfer and power expenditure correlations, extending over a mixing Reynolds number range from 55 to 200,000 were developed and compared with available data in the literature.
