History of fluid mechanics. 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. The field has undergone a continuous evolution, driven by human dependence on water, meteorological ...
1838-40 – Gotthilf Hagen and Jean Léonard Marie Poiseuille study laminar flow, independently establishing Hagen–Poiseuille equation. [ 1 ] 1841 – George Biddell Airy publishes the first correct formulation of Airy wave theory of water waves. [ 26 ] 1842 – Christian Doppler introduces the Doppler effect.
Carreau fluid in physics is a type of generalized Newtonian fluid where viscosity, , depends upon the shear rate, , by the following equation: Where: , , and are material coefficients. = viscosity at zero shear rate (Pa.s) = viscosity at infinite shear rate (Pa.s) = characteristic time (s) = power index. The dynamics of fluid motions is an ...
t. e. Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid (liquids and gases) with surfaces ...
Eulerian perspective of fluid velocity versus Lagrangian depiction of strain. In classical field theories, the Lagrangian specification of the flow field is a way of looking at fluid motion where the observer follows an individual fluid parcel as it moves through space and time. [1][2] Plotting the position of an individual parcel through time ...
Fluid mechanics, especially fluid dynamics, is an active field of research, typically mathematically complex. Many problems are partly or wholly unsolved and are best addressed by numerical methods, typically using computers. A modern discipline, called computational fluid dynamics (CFD), is devoted to this approach. [2]
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids — liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion).
