Concluding study of ventilation of turboalternators multiple path radial system

S. L. Henderson: This paper covers the results of a considerable amount of experimental work done subsequent to the papers written in 1 9 2 4 by Mr. Fechheimer and Mr. Bratt. As the later tests were made on stationary models, the constants could be determined more accurately than on a moving model, and the accuracy of the equations is demonstrated in the comparison between tests and calculations as given in Figs. 1 3 and 14. The results of this work are being used in the design of turbine generators with considerable practical benefit. On one design, in particular, it was possible to shorten the machine considerably through the use of these equations.
