Explain why fluid velocity is greatest where streamlines are closest together. (Hint: Consider the relationship between fluid velocity and the cross-sectional area through which it flows.) What is the difference between flux and flux density? What is irrotational flow of fluid? Wh...
Fluidics is the application of the physical properties of liquids and gases as a fluid to perform logic operations that control...
The conditions for which an incompressible flow occurs vary depending on the material properties of the fluid. Any fluid can be considered as incompressible under certain conditions on velocity and pressure. The tendency of a fluid to change volume when subjected to an external load depends on the...

McDonough defines a streamline as "a continuous line within a fluid such that the tangent at each point is the direction of the velocity vector at that point." In other words, a streamline shows the direction of the flow at any particular point in the flow. A streakline, according to ...
Computational fluid dynamics (CFD) is a branch of physics that deals with the study of the mechanics of fluid: liquid, plasmas and gasses and forces acting on them. CFG is based on Navier-Stroke equations that describe how pressure, velocity, density and temperature of a moving fluid are rel...
5Most CFD approaches involve the generation of a grid, or mesh, covering the flow domain. The aim is then to obtain values for the velocity, pressure, temperature, etc. at each grid node (for example, at the centre of each grid volume). The process in CFD is to take the governing,...
Rocky uses a resolved method for fluid-particle interaction, not relying on closure models for the fluid-particle momentum or heat transfer modeling. DEM particles are resolved by SPH elements. Both SPH and DEM use particle methods, and development of SPH for solving fluid applications is a natur...
Since agile programs are more fluid than traditional approaches, agile product management is a more flexible approach. One of the core concepts in agile is that the scope of a project is fluid, while resources stay the same. As such, in agile product management the team spends less time ...
