Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. [1]: 3 It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology.
In physics and chemistry, a non-Newtonian fluid is a fluid that does not follow Newton's law of viscosity, that is, it has variable viscosity dependent on stress.In particular, the viscosity of non-Newtonian fluids can change when subjected to force.
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
The Euler equations first appeared in published form in Euler's article "Principes généraux du mouvement des fluides", published in Mémoires de l'Académie des Sciences de Berlin in 1757 [3] (although Euler had previously presented his work to the Berlin Academy in 1752). [4]
The history of fluid mechanics is a fundamental strand of the history of physics and engineering.The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history.
ʿAbd (عبد) (for male) ʾAmah (أمة) (for female) Servant or worshipper. Muslims consider themselves servants and worshippers of God as per Islam.Common Muslim names such as Abdullah (Servant of God), Abdul-Malik (Servant of the King), Abdur-Rahmān (Slave of the Most Beneficent), Abdus-Salām (Slave of [the originator of] Peace), Abdur-Rahîm (Slave of the Most Merciful), all refer to ...
In physics, a fluid is a liquid, gas, or other material that may continuously move and deform (flow) under an applied shear stress, or external force. [1] They have zero shear modulus, or, in simpler terms, are substances which cannot resist any shear force applied to them.
A Newtonian fluid is a fluid in which the viscous stresses arising from its flow are at every point linearly correlated to the local strain rate — the rate of change of its deformation over time.
