Optimization of Rotational Hydrodynamic Cavitation Reactor Geometry

Fluids
A Rotary-Pulsation Apparatus (RPA), also known in the literature as a Rotational Hydrodynamic Cavitation Reactor (RHCR), is a device which typically consists of a rotating mechanism that generates pulsations or vibrations within a fluid.

Investigation of ammonia stripping with a hydrodynamic cavitation reactor

Ultrasonics Sonochemistry, 2020
Ammonia is a commonly used compound in the domestic and industrial fields. If ammonia found in wastewater after use is not treated, even at low concentrations it may cause toxic effects in the receiving environment. In this study, a hydrodynamic cavitation reactor (HDC) was designed with the aim of removing ammonia.

Hydrodynamic Cavitation Reactor for Efficient Biodiesel Production. A Review [PDF]

International Journal of Membrane Science and Technology, 2023
Biodiesel emerges as a viable option to replace fossil fuels, but the traditional process for the production of biodiesel requires a large energy expenditure, since transesterification has a slow conversion due to the immiscibility of alcohol and oil. On the other hand, with the hydrodynamic cavitation method, a shorter conversion time can be achieved ...
