Book Description
An experimental study was made on the effect of longitudinal vibrations on heat transfer by free convection from a horizontal cylinder in air, water, and a viscous hydrocarbon polymer (polybutene). Tests were conducted in which the frequency (f) was varied from 0 to 86 cps and the amplitude (x) from 0.005 to 0.16 in. Results of the testing showed no change in the rate of heat transfer for air. The rate of heat transfer in water increased up to 73% when bubbles were attached to the cylinder and increased up to 10% when no bubbles were present. Tests in the viscous hydrocarbon caused appreciable viscous heating. The rate of heat transfer in the viscous polymer increased to a maximum of 216%. The tests in water and the hydrocarbon polymer showed that the rate of heat transfer began to increase at a vibration intensity of fx = 0.4 and fx = 1.0 respectively (fx is the intensity of vibration cps in.). It is recommended that further tests be made using larger amplitudes and frequencies. (Author).
