In the present work, the experimental characterization of the formation and development of the cavitation cloud in different liquid temperatures 20, 30, 40, and 50 °C is reported. For this, a hydraulic installation was built whose main element is a Venturi tube with a rectangular section, with it, the necessary flow conditions were generated to form cavitation and measure the thermodynamic properties for the calculation of the Thoma and Reynolds adimensional numbers. The average bias error of the measurements did not exceed 1%, for this reason, the good quality of the calculation in the Thoma and Reynolds numbers was ensured. With the numbers of Thoma "σ" and Re, the different phases of the cavitation cloud were characterized, from incipient, quasi, developed, and supercavitation in the temperature range of the experiment, finding that the transition from incipient to developed cavitation is easier at room temperature since the flow rate will increase only 15.82% compared to the other temperatures. Finally, the density of the fluid in the temperature range of the test remained constant, since it did not vary more than 1%, so it did not affect the flow regime.
