On the Measurement of Void Fraction in Hydraulic Fluid with Entrained Bubbles

抄録

Recently pressure and speed of hydraulic equipment tend to grow higher and higher, and therefore, cavitation and aeration in hydraulic fluid flow become a problem of engineering. So it is important to measure the bubble content of the hydraulic fluid quantitatively. For our study we used the light transmission method to measure the void fraction of bubbles in hydraulic fluid instantaneously. So we studied experimentally by using this method and discussed the results by theoretical analysis.
