Flow Induced Failures of Copper Drinking Water Tube
… that include concentration cell corrosion, cavitation, particle/bubble impingement and high velocity impingement. Concentration cell effects resulting from exposing different copper surfaces to different flow regimes created a strong electrochemical cell that caused rapid corrosion that …

AN EXPERIMENTAL AND NUMERICAL STUDY ON CAVITATION BUBBLE DYNAMICS AND ITS BIOMEDICAL APPLICATIONS
A thorough understanding of cavitation bubble dynamics is critical to mitigate cavitation damage or develop practical applications. An important field of study is the interaction of a single cavitation bubble with neighbouring structure(s). A cavitation bubble collapse near a finite elastic beam, …

NON-DIMENSIONAL DATA-DRIVEN MODELS OF COMPUTATIONAL FLUID DYNAMICS (CFD) OF MULTI-PHASE FLOW IN ANNULUS
… and threaten its liability. For example, the cavitation damage the elastomer sealing surface and lead to BOP malfunction or failure. To understand the flow characteristics under extreme working conditions and ultimately enable the estimation of the BOP lifetime, experimental approaches and …

Boiler feed pump low load – leak off recirculation study
… a risk that the boiler feed pump may experience cavitation and overheating at low load and start-up conditions. These plants make use of a leak off or recirculation system that diverts some of the flow back to the feed water tank, ensuring that a minimum flow through the pump is maintained at low …

An investigation to predict the sub-atmospheric pressure on high spillways
… for release of flood discharges for dams. Severe cavitation damage has occurred on many high spillways around the world, including Russia, Pakistan, Venezuela, and Iran. In Iran, this phenomena caused serious damage to the Karun I dam spillway. Many studies and investigations related to cavitation …

Origin of Creep-Fatigue Back Stress and its Effect on Deformation and Damage
… strains. In addition, development of creep cavitation damage was characterized using small angle neutron scattering (SANS) and high-speed atomic force microscope (HS-AFM) techniques. Intergranular strains were found to significantly affect the minimum creep deformation rate of type 316H …

Detailed simulations of bubble-cluster dynamics
… bubble clusters can be an important mechanism of damage to adjacent material surfaces in both engineering and biomedical applications. Because of their complexity, past theoretical studies have generally been restricted to significantly simplified models, such as homogenized continuum models based …
