Note an experiments on the temperature and velocity in the wake of a heated cylindrical obstacle

Abstract

For the experiments, the results of which are shown in fig. 3, a solid carbon cylindrical rod of diameter 5/8-inch was mounted in a 3-feet wind tunnel of the N. P. L. type. The length of the rod was 3 feet. The rod was directly heated by passing through it a current of about 70 amps/ The experiments, result of which given in fig. 4, were made with a thin walled copper cylinder having a lenticular section (2.·60 inches by 0.53 inch) mounted in the I-foot open-jet junnel. The cylinder was heated by two carbon heaters of diameter 5/16-inch. The current through the carbon rods was 19 amps.
