3D Analysis of Cavitation in Control Valve by Pressure Variation
The phenomenon of cavitation can severely affect the working of valves used to control liquid flow. Cavitation occurs when the pressure is reduced and the water evaporates, forming bubbles. When bubbles pass into an area of higher pressure, they condense and collapse, releasing a large ... Read More
Residence Time Distribution for Tubular Reactors
In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal ... Read More
Simulation of a Piezoelectric Loudspeaker for Hearing Aids and Experimental Validation
The use of piezoelectric materials in hearing aid loudspeakers, also called receivers, presents technical and economic advantages such as reducing the number of parts of the system and its manufacturing cost. However, the performance of such systems is still not competitive when compared ... Read More
