fluid mechanics Aerodynamics, branch of physics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies passing through such a fluid. Aerodynamics seeks, in particular, to explain the principles governing the flight of aircraft, rockets, and missiles. It is also concerned with the design of automobiles, high-speed trains, and ships, as well as with the construction of such structures as bridges and tall buildings to determine their resistance to high winds. Read More on This Topic airplane: Aerodynamics An aircraft in straight-and-level unaccelerated flight has four forces acting on it. (In turning, diving, or climbing flight, additional… Observations of the flight of birds and projectiles stirred speculation among the ancients as to the forces involved and the manner of their interaction. They, however, had no real knowledge of the physical properties of air, nor did they attempt a systematic study of those properties. Most of their ideas reflected a belief that the air provided a sustaining or impelling force. These notions were based to a large degree on the principles of hydrostatics (the study of the pressures of liquids) as they were then understood. Thus,... Source

Highlights•A numerical model of a micro-tube was generated using VOF-CSF strategy for fluid-fluid and fluid-fluid-surface tracking•Adaptive Mesh Refinement (AMR) was used for Mesh sensitivity analysis and experimental data for physical validation•CDC (Capillary Desaturation Curve) curves were generated considering dynamic contact angle•Three correlations were proposed for residual saturation of the displaced fluid with maximum average relative error of 12%AbstractThe main goal of this study is to numerically investigate the immiscible fluid-fluid displacement at the micro-level under low inertial and buoyancy forces. To this end, a micro capillary tube was constructed, and the fluid-fluid interface and fluid-fluid-wall triple line were tracked using VOF (Volume of Fluid)-CSF (Continuum Surface Force) strategy. Mesh-independency analysis was conducted by utilizing the Adaptive Mesh-Refinement (AMR) technique. Simulation results agreed well with the experimental data obtained from literature with the AARD (Average Absolute Relative Deviation) of around 10%. The validated model was then used to generate the CDC (Capillary Desaturation Curve) curves for different wall wettabilities, considering the dynamic contact angle in the simulations. The generated CDC curves at the breakthrough time showed that there are three different zones, namely low-Ca, transitional, and high-Ca region. The only difference between saturation profiles of different wettabilities was in the transition... Source

Fluid mechanics, science concerned with the response of fluids to forces exerted upon them. It is a branch of classical physics with applications of great importance in hydraulic and aeronautical engineering, chemical engineering, meteorology, and zoology.The most familiar fluid is of course water, and an encyclopaedia of the 19th century probably would have dealt with the subject under the separate headings of hydrostatics, the science of water at rest, and hydrodynamics, the science of water in motion. Archimedes founded hydrostatics in about 250 bc when, according to legend, he leapt out of his bath and ran naked through the streets of Syracuse crying “Eureka!”; it has undergone rather little development since. The foundations of hydrodynamics, on the other hand, were not laid until the 18th century when mathematicians such as Leonhard Euler and Daniel Bernoulli began to explore the consequences, for a virtually continuous medium like water, of the dynamic principles that Newton had enunciated for systems composed of discrete particles. Their work was continued in the 19th century by several mathematicians and physicists of the first rank, notably G.G. Stokes and William Thomson. By the end of the century explanations had been found for a host of intriguing phenomena... Source

Home References Streaklines show the airflow around a tennis ball. (Image: © NASA) Fluid dynamics is "the branch of applied science that is concerned with the movement of liquids and gases," according to the American Heritage Dictionary. Fluid dynamics is one of two branches of fluid mechanics, which is the study of fluids and how forces affect them. (The other branch is fluid statics, which deals with fluids at rest.) Scientists across several fields study fluid dynamics. Fluid dynamics provides methods for studying the evolution of stars, ocean currents, weather patterns, plate tectonics and even blood circulation. Some important technological applications of fluid dynamics include rocket engines, wind turbines, oil pipelines and air conditioning systems. What is flow?The movement of liquids and gases is generally referred to as "flow," a concept that describes how fluids behave and how they interact with their surrounding environment — for example, water moving through a channel or pipe, or over a surface. Flow can be either steady or unsteady. In his lecture notes, "Lectures in Elementary Fluid Dynamics" (University of Kentucky, 2009) J. M. McDonough, a professor of engineering at the University of Kentucky,... Source
