The hydrodynamic cavitation in a Venturi tube is studied both theoretically and experimentally. A lumped parameter model was developed to describe the accumulation and dissipation of energy in the biphasic flow as a function of the bubble population characteristics (mean volume, standard deviation, and void fraction). Resistance, capacitance, inductance, and frequency lumped-parameters were identified applying the fluid conservation equations (mass and momentum) along with electrical/hydraulic analogies. Experiments with 1,2-propanediol were carried out in a hydraulic circuit composed of valves, a pump, and a Venturi nozzle. The acoustic noise generated (at different cavitation regimes) by the passage of the fluid through the tube was acquired with a piezoelectric sensor. After processing the experimental signals, the system frequency at each operation condition was determined. Plausible estimations of the void fraction were obtained at different experimental frequencies by evaluating a theoretical expression of the frequency lumped-parameter. This semi-empirical technique might be a low-cost alternative when the void fraction of a flow needs to be determined and tomography devices are not available.

Resistance parameter behavior (Eqs. (9) and (16), f=0.91,ϑ=0.25), for a homogeneous (solid line, β=0) and a heterogeneous (dashed line, β=1.5) bubble population in the inlet and outlet of the constriction zone as a function of their pressure drop, as well as the void fraction with VB between 4.2×10−24m3 and 4.2×10−6m3 and the Reynolds number. The solid symbols are the maximum resistance values and show the respective value of VB. It should be noted that bubble populations with homogeneous volumes or with small mean volumes VB≈10 nm3 show major opposition to flowing by the geometric changes in the Venturi profile.

Capacitance parameter behavior (Eq. (23)) of a homogeneous (solid line, β=0) and a heterogeneous (dashed line, β=1.5) flow regimen in the inlet and outlet of the constriction zone as a function of the pressure drop, and void fraction with VB between 4.2×10−24m3 and 4.2×10−6m3. The solid symbols are the maximum capacitance values and show the respective value of VB. It is observed that bubble populations with homogeneous volumes or with major mean volumes 20nm3>VB<35nm3 tend to store more energy than bubble populations with small mean volumes.
