Abstract
Possible ways of constructing a general model of cavitation reactors are considered. A mathematical model is proposed that without using any limiting assumptions describes adequately the dynamics of vapor-gas bubbles and the behavior of a cavitation cluster in a wide range of regime parameters. In the framework of the model, the influence of gas content and liquid temperature on the cavitation intensity is considered. The possibility of modifying the model as applied to optimizing the operation of cavitation reactors is discussed.
Highlights
In recent years there has been a trend of widespread use of hydrodynamic cavitation in various industrial technologies, such as wastewater treatment and sterilization, the creation of nano-emulsions, the synthesis of biodiesel, food processing and others [1,2]
Cavitation mechanisms are initiated in acoustic fields with using various ultrasonic emitters or by creating optimal hydrodynamic conditions in the liquid flow [1,2,3,4,5]
The experience in using of these devices in scientific research and in carrying out various technological operations proves that the realization of the cavitation phenomena allows to dramatically affects the heat and mass transfer, the hydrodynamic, chemical and biophysical processes in liquid at the micro- and nanoscales [2,7,10,11]
Summary
In recent years there has been a trend of widespread use of hydrodynamic cavitation in various industrial technologies, such as wastewater treatment and sterilization, the creation of nano-emulsions, the synthesis of biodiesel, food processing and others [1,2]. This allows the calculation of non-stationary fields of velocities, temperatures and pressures in liquid within the cluster, where processed micro-objects are present [9].
