... Fluids in Motion • A fluid flowing past a stationary surface experiences a force opposing the flow. This tendency of a fluid to resist flow is referred to as the viscosity of the fluid. • Fluids like air have low viscosities, thick fluids like water are more viscous, and fluids like honey and molas ...

Problems with Pitots - Source Testing Association
... One area requiring research is the effect of sample temperature on Pitot measurements. The use of a hot wind tunnel and laser Doppler anemometer (LDA) should facilitate this. After a Pitot has been characterised in the hot wind tunnel the LDA could be transferred to a ‘hot’ stack and an intercompari ...

Lecture 17
... • As discussed in Chapter 16, when a body is subjected to general plane motion, it undergoes a combination of translation and rotation. • First, a coordinate system with its origin at an arbitrary point P is established. The x-y axes should not rotate and can either be fixed or translate with consta ...

The added mass of a spherical projectile
... velocity, as expected from Eq. (1), is strongly modified by changes in CD . At the “drag crisis,” CD abruptly drops from approximately 0.5 for smaller values of Re to values as low as 0.07 before slowly rising again. The critical Reynolds number at which the drop occurs decreases with increasing sur ...

Fluid dynamics
In physics, fluid dynamics is a subdiscipline of fluid mechanics that deals with fluid flow—the natural science of fluids (liquids and gases) in motion. It has several subdisciplines itself, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Some of its principles are even used in traffic engineering, where traffic is treated as a continuous fluid, and crowd dynamics. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves calculating various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time.Before the twentieth century, hydrodynamics was synonymous with fluid dynamics. This is still reflected in names of some fluid dynamics topics, like magnetohydrodynamics and hydrodynamic stability, both of which can also be applied to gases.
