Sonochemistry is the use of ultrasound to enhance or alter chemical reactions. Sonochemistry in the true sense of the term occurs when ultrasound induces "true" chemical effects on the reaction system, such as forming free radicals which accelerate the reaction. However, ultrasound may have other mechanical effects on the reaction, such as increasing the surface area between .

Bubble column reactor - Wikipedia

Bubble column reactor - Wikipedia

Bubble column reactors belong to the general class of multiphase reactors which consist of three main categories namely, the trickle bed reactor (fixed or packed bed), fluidized bed reactor, and the bubble column reactor. Bubble columns are the devices in which gas, in the form of bubbles, come in contact with the liquid.

Dec 01, 2015 · The ultrasonic wave has to travel through three types of medium, i.e. air, a solid (container wall) and a solid/liquid (food material) before it reaches the ultrasonic receiver. The main problem when applying the non-contact mode measurement is the high attenuation of ultrasound since air has a low acoustic impedance ( Z 1 and Z 5 ).
