Ralph Bagnold (1920-2021) was a prominent British physicist and engineer, best known for his pioneering work in the field of sediment transport and his studies of fluid mechanics, primarily in relation to the movement of sand and dust in arid environments. He founded the Desert Research Institute in the 1950s and conducted extensive fieldwork in the Sahara Desert, where he explored the mechanics of sand dunes and the processes that shape desert landscapes.

Simen Ådnøy Ellingsen could refer to a specific individual, but there is no widely recognized public figure or entity by that name as of my last knowledge update in October 2023. It's possible that he may be a private individual or someone who has gained recognition after that date.

Robert Edmund Froude does not appear to be a widely recognized figure in historical or contemporary contexts based on information available up to October 2023. It’s possible that you may be referring to someone else or that the name is notable in a specific or niche area not covered in common knowledge sources.

"Rose Morton" could refer to various subjects depending on the context. It may refer to a person, a character in a story, a product, or a term used in a specific industry. Without additional context, it's challenging to provide an accurate description.

Tim Pedley is a prominent British mathematician known for his work in fluid dynamics and applied mathematics. He has contributed significantly to computational fluid dynamics (CFD) and the study of waves and instabilities in fluids. Pedley has published numerous research papers and is often cited in works related to theoretical and applied aspects of fluid mechanics.

Viktor Kaplan is an Austrian engineer and inventor best known for his work in the development of the Kaplan turbine, which is a type of water turbine used primarily for generating hydroelectric power. The Kaplan turbine is particularly effective in low-head hydroelectric installations and is characterized by its adjustable blades, allowing it to operate efficiently under varying water flow conditions. Kaplan's innovations significantly advanced turbine technology and hydroelectric power generation, contributing to the efficiency and effectiveness of renewable energy sources.

Veniamin Levich is a prominent physicist known for his contributions to the fields of electrochemistry and fluid mechanics. He is particularly recognized for his work on the behavior of fluids in thin films and complex fluids, as well as his research on ion transport and other phenomena at the microscopic scale.

Wolfgang Haack could refer to a few different things depending on the context, but there is no widely known figure or concept that stands out with this name in popular culture, science, or history as of my last update in October 2023. It’s possible that Wolfgang Haack might be a less prominent individual in academia, business, or other areas not covered broadly in available datasets.

Wolfgang Liebe does not appear to be a widely recognized or notable figure in popular culture, science, or history based on the data available up until October 2023. It's possible that he may be a private individual, or the name could refer to someone with local significance or a specific context not broadly documented.

W. H. Besant refers to Sir Walter Besant, an English novelist, historian, and biographer who was active in the late 19th and early 20th centuries. He is well-known for his works of fiction, many of which are set in London and often explore themes related to social issues and the lives of ordinary people. Besant also played a significant role in promoting the study of London’s history and wrote extensively about the city.

Non-Newtonian fluids are fluids whose viscosity changes with the applied shear stress or shear rate, in contrast to Newtonian fluids, which have a constant viscosity regardless of the applied stress. In simpler terms, the flow behavior of non-Newtonian fluids is dependent on the conditions under which they are subjected to force.

Walter Munk was a renowned American oceanographer and physicist, often referred to as the "Einstein of the Oceans." Born on October 19, 1917, and passing away on February 8, 2023, he made significant contributions to our understanding of ocean wave dynamics, tides, and climate. Munk was particularly noted for his work in acoustic oceanography and his role in the development of techniques for measuring ocean currents and waves.

"Sunday" is a song by the British rock band Foals, featured on their album *Everything Not Saved Will Be Lost – Part 2*, released in 2019. The song encapsulates themes of love, longing, and the passage of time, characterized by its dynamic instrumentation and emotive lyrics. It showcases Foals' signature sound, blending elements of rock, art rock, and electronic music.

In fluid dynamics, the Laplace equation is often applied in the context of irrotational flow, which is characterized by the absence of vorticity. For an incompressible, irrotational flow, the flow velocity can be described with a potential function, commonly denoted as \( \phi \).

Eddy diffusion is a process that describes the transport and mixing of particles, heat, or other substances in a medium, such as air or water, due to turbulent eddies or vortices. This phenomenon is particularly important in the fields of fluid dynamics, meteorology, oceanography, and environmental science. In turbulent flows, eddies of varying sizes are created as a result of chaotic fluid motion.

The Emerson Cavitation Tunnel is a specialized facility used for testing and studying cavitation phenomena in fluid dynamics, particularly in relation to marine and hydraulic applications. Cavitation occurs when a liquid is subjected to rapid changes in pressure, leading to the formation of vapor bubbles. These bubbles can collapse violently, causing damage to surfaces and affecting the performance of propellers, pumps, and other fluid machinery. Emerson's facility typically includes a long, submerged tunnel where water is circulated at controlled velocities.
