| dc.description.abstract | This study describes the effect of jet Prandtl number on the convective heat transfer from a rotating disk cooled by a single jet of impinging oil. Data were taken for different combinations of jet flowrates, jet temperatures, disk rotational speeds, disk temperatures, nozzle diameters and disk diameters. Three sizes of nozzle diameters were used, 0.079 in. (0.2 cm), 0.158 in. (0.4 cm) and 0.315 in. (0.8 cm). Three sizes of disk diameters were used, 3.937 in. (10.0 cm), 7.874 in. (20.0 cm) and 11.134 in. (28.28 cm). Nondimensional correlations of Nusselt number are given in terms of jet Reynolds number, Prandtl number and rotational Reynolds number. The parameter ranges that are covered in this study are:80 < jet Prandtl number < 400; 200 < jet Reynolds number < 1300; 25,000 < rotational Reynolds number < 500,000. | |
