Flow rate may refer to: . Flow measurement, a quantification of bulk fluid movement; Mass flow rate (ṁ or μ), the mass of a substance which passes per unit of time; Volumetric flow rate (Q or ˙), the volume of fluid which passes per unit time
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 ...
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 water and other liquids in motion).
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.
