| titleOfInvention | A method and device for quantitatively measuring cavitation strength in clear water or sandy water |
| abstract | The invention relates to a method and a device for quantitatively measuring the cavitation strength of clean water or sand-containing water. In this scheme, FeSO 4 is used to capture OH produced by cavitation in water, and Fe 2+ is oxidized to Fe 3+ . Under certain conditions, the OH concentration has a positive response relationship with the Fe 3+ concentration, and the absorbance of the solution meets the Fe 3+ concentration. Lambert-Beer's law, detecting the absorbance in the solution can quantitatively characterize the cavitation intensity of clear water or sandy water. The method and device provided by the invention can not only quantitatively measure the cavitation strength in clean water, but also quantitatively measure the cavitation strength in sand-containing water, and the stirring device provided can prevent sediment precipitation during the test and ensure that the reaction is fully carried out. Compared with the existing similar methods, the method of the invention has many advantages such as high sensitivity, good accuracy, simplicity and easiness. |
