The distortion of longitudinal pulses in slightly curved elastic rods is discussed in terms of an elementary theory in which the effects of rotary inertia and radial shear are neglected. Moreover, when the wavelength of the pulse is long e…

Evaporation and Diffusion Effect on an Oscillating Bubble Open

Tunglu Wang, D. Y. Hsieh · 1971

Materials science Physics Chemistry

The effect of diffusion and evaporation on the oscillation of a bubble is analyzed. It is found that the modification due to diffusion alone is significant only when the diffusion length is large compared with the size of the bubble. The m…
