  2. Hydrodynamic separator - Wikipedia

    en.wikipedia.org/wiki/Hydrodynamic_separator

    In civil engineering (specifically hydraulic engineering), a hydrodynamic separator (HDS) is a stormwater management device that uses cyclonic separation to control water pollution. They are designed as flow-through structures with a settling or separation unit to remove sediment and other pollutants. [ 1 ]

  3. Spiral separator - Wikipedia

    en.wikipedia.org/wiki/Spiral_separator

    A spiral separator may process a couple tons per hour of ore, per flight, and multiple flights may be stacked in the same space as one, to improve capacity. [2] Many things can be done to improve the separation efficiency, including: changing the rate of material feed; changing the grain size of the material; changing the slurry mass percentage [3]

  4. Dog (engineering) - Wikipedia

    en.wikipedia.org/wiki/Dog_(engineering)

    Unless the dog is engaged, the gear will simply freewheel on the shaft. This word usage is a metaphor derived from the idea of a dog (animal) biting and holding on, the "dog" name derived from the basic idea of how a dog jaw locks on, by the movement of the jaw, or by the presence of many teeth. In engineering the "dog" device has some special ...

  5. ANUGA Hydro - Wikipedia

    en.wikipedia.org/wiki/ANUGA_Hydro

    ANUGA is stable even in extreme flow with high Froude numbers. An example of this is the 1928 St Francis Dam Break in California that resulted in extreme flow velocities and complex waves in a tortuous valley. ANUGA ran this model with full volumetric mass balance preserved at all times and no instabilities anywhere in the model.

  6. Centrifugal water–oil separator - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_water–oil...

    In a centrifugal oil and water separator, the force of gravity is one-thousand [citation needed] times greater that of the coalescing plate pack separator or the petrol interceptor, so the separation is much greater. Not only is the force of separation greater, but there are fewer working parts so maintenance is much easier and cheaper.

  7. Water tunnel (hydrodynamic) - Wikipedia

    en.wikipedia.org/wiki/Water_tunnel_(hydrodynamic)

    A water tunnel is an experimental facility used for testing the hydrodynamic behavior of submerged bodies in flowing water. It functions similar to a recirculating wind tunnel , but uses water as the working fluid, and related phenomena are investigated, such as measuring the forces on scale models of submarines or lift and drag on hydrofoils .

  8. Smoothed-particle hydrodynamics - Wikipedia

    en.wikipedia.org/.../Smoothed-particle_hydrodynamics

    The computational cost of SPH simulations per number of particles is significantly less than the cost of grid-based simulations per number of cells when the metric of interest is related to fluid density (e.g., the probability density function of density fluctuations). [6] This is the case because in SPH the resolution is put where the matter is.

  9. Pressure swing adsorption - Wikipedia

    en.wikipedia.org/wiki/Pressure_swing_adsorption

    The consumer will most likely consider indices which have a more directly measurable difference in the overall system, like the amount of product gas divided by the system weight and size, the system initial and maintenance costs, the system power consumption or other operational costs, and reliability.
