  2. Free surface effect - Wikipedia

    en.wikipedia.org/wiki/Free_surface_effect

    A liquid hitting a wall in a container will cause sloshing. The free surface effect is a mechanism which can cause a watercraft to become unstable and capsize. [1]It refers to the tendency of liquids — and of unbound aggregates of small solid objects, like seeds, gravel, or crushed ore, whose behavior approximates that of liquids — to move in response to changes in the attitude of a craft ...

  3. Slosh dynamics - Wikipedia

    en.wikipedia.org/wiki/Slosh_dynamics

    Similar phenomena can cause pogo oscillation and can result in structural failure of a space vehicle. Another example is problematic interaction with the spacecraft's Attitude Control System (ACS), especially for spinning satellites [ 8 ] which can suffer resonance between slosh and nutation , or adverse changes to the rotational inertia .

  4. Baffle - Wikipedia

    en.wikipedia.org/wiki/Baffle

    Baffle (liquid mixing), auxiliary devices employed in tank which suppress the effects of slosh dynamics; Baffle (heat transfer), a flow-directing or obstructing vane or panel used in some industrial process vessels (tanks) Baffle (medicine), a tunnel or wall surgically constructed within the heart or primary blood vessels to redirect blood flow

  5. Turnstile - Wikipedia

    en.wikipedia.org/wiki/Turnstile

    In addition, a turnstile can restrict passage only to people who insert a coin, ticket, transit pass, security credential, or other method of payment or verification. Modern turnstiles can incorporate biometrics , including retina scanning, fingerprints, and other individual human characteristics which can be scanned.

  6. Baffle (heat transfer) - Wikipedia

    en.wikipedia.org/wiki/Baffle_(heat_transfer)

    In this case the baffle helps increase the efficiency of the stove as more heat leaves the gas before it exits. The baffles prevent the rotational flow without affecting radial or longitudinal flow. The tank is provided with baffles which prevent swirling and vortex formation. Except in very large tanks, four(4) baffles are placed.

  7. Bafflestone - Wikipedia

    en.wikipedia.org/wiki/Bafflestone

    A bafflestone in thin section (width of image is 34 mm). Bafflestone is a type of carbonate rock.. The Dunham Classification (Dunham, 1962 [1]) of limestones employed the term boundstone to encompass all carbonate rocks that exhibited any evidence of the original components being organically-bound together at the time of deposition.

  8. If a tree falls in a forest and no one is around to hear it ...

    en.wikipedia.org/wiki/If_a_tree_falls_in_a_forest...

    We can define sound as our perception of air vibrations. Therefore, sound does not exist if we do not hear it. When a tree falls, the motion disturbs the air and sends off air waves. This physical phenomenon, which can be measured by instruments other than our ears, exists regardless of human perception (seeing or hearing) of it.

  9. Drop structure - Wikipedia

    en.wikipedia.org/wiki/Drop_structure

    The vertical hard basin drop structure, also called a dissipation wall, is the basic type of drop structure.The vertical hard basin drop consists of a vertical cutoff wall, usually built of concrete, that is usually laid perpendicular to the stream flow, and an impact basin, not unlike a stream pool, to catch the discharged water.
