The most common examples of this kind of wear are pump impellers and bends when a sudden change in the direction of liquid occurs. Cavitation is usually divided into two classes of behaviour inertial or transient cavitation and non inertial cavitation.

Non inertial cavitation is the process in which a bubble in a fluid ... field . Such cavitation is often employed in ultrasonic cleaning baths and can also be observed in pumps, propellers, etc. Since the shock waves formed by cavitation are strong enough to significantly damage moving parts, cavitation is usually an undesirable phenomenon.

Megasonic Cleaning is a type of acoustic cleaning , related to ultrasonic cleaning . It is a gentler cleaning mechanism, less likely to cause damage, and is used in wafer, medical implant, and industrial part cleaning. Similar to ultrasonic cleaning, megasonics utilizes a transducer , usually composed of piezoelectric crystal s to create megasonic energy. Megasonic energy is of a higher frequency 800 2000 kHz than typical ultrasonic cleaners 100 kHz . As a result, the cavitation that occurs is gentler and on a much smaller scale. Megasonics are currently used mainly in the silicon industry. Megasonics cleaning compared to ultrasonic cleaning The difference between ultrasonic cleaning and megasonics cleaning lies in the frequency that is used to generate the acoustic waves. Ultrasonic cleaning uses lower frequencies it produces random cavitation. Megasonics cleaning uses higher frequencies at 1000 kHz it produces controlled cavitation. An important distinction between the two methods is that the higher megasonic frequencies do not cause the violent cavitation effects found with ultrasonic frequencies. This significantly reduces or eliminates cavitation erosion and the likelihood of surface damage to the product being cleaned. Parts that would be damaged by ultrasonic frequencies or cavitation effects can often be cleaned without damage in a megasonic bath using the same solution. With ultrasonics, cavitation occurs throughout the tank, and all sides of submerged parts are cleaned. With megasonics, only the side of the part that is facing the transducer s is cleaned.

It expresses the relationship between a local pressure drop e.g. over a restriction and the kinetic energy per volume, and is used to characterize losses in the flow, where a perfect frictionless flow corresponds to an Euler number of 1. It is defined as math mathrm Eu frac p mathrm upstream p mathrm downstream rho V 2 math where math rho math is the density of the fluid. math p upstream math is the upstream pressure. math p downstream math is the downstream pressure. math V math is a characteristic velocity of the flow. The cavitation number has a similar structure, but a different meaning and use The Cavitation number is a dimensionless number used in flow calculations.

Orphan date February 2009 Sonophoresis is a process that exponentially increases the absorption of semisolid topical compounds transdermal delivery into the Epidermis skin epidermis , dermis and skin appendages. Sonophoresis occurs because ultrasound waves stimulate micro vibrations within the skin epidermis and increase the overall kinetic energy of molecules making up topical agents. It is widely used in hospitals to deliver drugs through the skin. Pharmacists compound the drugs by mixing them with a coupling agent gel, cream, ointment that transfers ultrasonic energy from the ultrasound transducer to the skin. The ultrasound probably enhances drug transport by cavitation , microstreaming, and heating. Sonophoresis is also used without drug delivery in physical therapy, and as a complementary modality for iontophoresis .

Erosion corrosion is a degradation of material surface due to mechanical action, often by impinging liquid, abrasion by a slurry, particles suspended in fast flowing liquid or gas, bubbles or droplets, cavitation , etc. The mechanism can be described as follows mechanical erosion of the material, or protective or passive oxide layer on its surface, enhanced corrosion of the material, if the corrosion rate of the material depends on the thickness of the oxide layer. The mechanism of erosion corrosion, the materials affected by it, and the conditions when it occurs are generally different than that of flow accelerated corrosion , although the last one is sometimes classified as a sub type of erosion corrosion. Surface chemistry can play a role in erosion corrosion due to Mechanochemistry mechanochemical effects. Erosion corrosion is the second most common cause of Erosion corrosion of copper water tubes copper tube failure .

inline date December 2010 NOREM is a hardfacing material developed by Electric Power Research Institute EPRI to deal with radio safety issues associated with the use of cobalt alloys in nuclear power station coolant systems see stellite for a discussion of the problem . It is a Solid solution strengthening solid solution strengthened austenitic matrix with a continuous network of eutectic and non eutectic carbides at the grain boundaries. It is intended to be deposited by various welding processes. Characteristics There are eight variants of NOREM currently available, depending on application and designated 02, 02A, 03A, 03B, 04A, 04B, 05A, 05B. A typical elemental composition is 60 iron, 25 chromium, 4.5 manganese, 4.0 nickel, 3.3 silicon, 2.0 molybdenum, 1.2 carbon. Earlier compositions included either significantly more manganese 12 in alloy 04 or significantly more nickel 8 in alloy M2 . These are extremely hardness hard alloys. NOREM 02 is ten times as resistant as 308 stainless steel to cavitation erosion . They are essentially corrosion immune under the conditions inside CANDU reactor s and erode at about 200 micrograms per square centimetre per year under pressurized water reactor conditions. Due to the high hardness, the strength is relatively low approximately convert 120 ksi abbr on yield strength and it fails at 0.6 elongation. Use in power plants The first use of NOREM was as replacement discs in three Chemical Volume Control System isolation valves at Consolidated Edison s Indian Point Energy Center Indian Point unit 2. It is now used in about 800 valves installed by about 30 utility companies. There has been one case of a NOREM valve disc being found damaged, at the Callaway Nuclear Generating Station , though it seems the valve was not being used in an appropriate application. Given the high cavitation resistance, NOREM has been tested for hydroelectric applications it seems not to be as impressively cavitation resistant in the field as in the lab, t ... more details
