The thickness of a liquid film formed with liquid column oscillation was investigated experimentally. The liquid column was oscillated sinusoidally to simulate the flow phenomena in pulsating heat pipes. A vertically located circular glass tube with an inner diameter of 2 mm was used as the test channel. The average liquid film thickness during liquid column oscillation varied as a function of the average capillary number. The experimental results were compared to those in the horizontal pipe. The results showed that the gravity affected the thickness of the liquid film.
