Results are presented for a series of experiments conducted for the purpose of studying the local and overall effects of a resonant acoustic vibration on the heat transfer coefficient for air flowing through a constant temperature isothermal tube at Graetz Numbers from 33 to 5400. The local heat transfer coefficient is shown to vary periodically between the nodes and loops of the resonant sound wave. Local heat transfer coeffients up to 3.6 times the no-sound values have been obtained. Extensive tables of data are included for possible use in analytical investigations. Sound pressure levels to 162 decibels are reported.
