Book excerpt: Sonoluminescence is the effect of producing light from sound and occurs when a gas bubble is trapped in a fluid filled cavity and is forced to collapse under a barrage of sound waves. Frenzel and Schultes discovered this phenomenon in 1934 while exposing acoustic waves to photographic plates. This effect was not well understood until 1988 when Crum and Gaitan discovered the necessary conditions for producing single bubble sonoluminescence in the laboratory. The luminescence is a result of the bubble violently collapsing from sound waves and this shares a close association with vibratory cavitation. Cavitation erosion is known to cause damage to rotational machinery when the collapse is near to surfaces due to the high pressures associated with bubble collapse. With these high pressures and temperatures there is a considerable amount of damage to the outside layer of a bearing, thereby, reducing its useful life. An experiment was constructed to generate sonoluminescence in the laboratory in order to obtain a greater understanding of this phenomenon and its association with bubble cavitation. Most of the research was done to investigate how to obtain single bubble sonoluminescence under different conditions and to determine how to detect it. Success in this has inspired several theories on how to use the methods for generating sonoluminescence to control cavitation in fluids under industrial conditions.

Book excerpt: The objective of this study was to develop a test procedure to evaluate the ability of a heavy-duty diesel engine coolant to provide protection against damage resulting from a phenomenon known as cylinder liner cavitation corrosion. The engine cavitation test procedure was developed by modifying a production OEM diesel engine to consistently produce the operating conditions that accelerate damage from cylinder liner cavitation. The resulting, 250-h test procedure was able to quantify a coolant's ability to protect wet-sleeve cylinder liners from cavitation corrosion. Dozens of coolants were evaluated using this test procedure. The ranking of cylinder liner pit area counts from this procedure's discrimination matrix was in agreement with the ranking of pit area results seen in high-mileage field tests. Conversely, upon investigation, an acceptable correlation could not be established between field test pit area counts and the results from a known bench test. Obtaining results in a few weeks from a short duration procedure such as this can offer a coolant formulator advantages compared to waiting for the completion of a properly conducted field test. This test procedure creates an accelerated, yet realistic level of liner cavitation that ranks protection levels of coolants being evaluated. This ranking or discrimination is often not possible in field testing because the field test is run under mild service conditions or the engine components have little tendency to promote liner pitting. In addition, the difficulty in controlling field tests often yields unusable, inaccurate results. The test procedure was shown to be repeatable within labs and reproducible between labs thus confirming the viability of this test procedure as a useful tool to assess a coolant's ability to protect against cylinder liner cavitation damage. It is recommended that the presently developed test procedure be considered for adoption as an ASTM test method.

Book excerpt: The book deals with cavitation damage to diesel engine parts, methods of controlling this damage, and techniques for calculating and accelerated testing of parts for cavitation resistance. Principal factors leading to cavitation erosion in diesel engines are examined: water temperature in diesel engine cooling jackets, design factors, and operating factors. Methods of calculating vibrational acceleration of cylinder liners are outlined; estimates are presented of the possible amplitudes and critical accelerations of vibrations in the surfaces of parts swept by water in a diesel engine.
