CORE DEFINITION

When a fluid flows through a narrow section of a pipe, the flow velocity increases and the pressure decreases. Vacuum cleaners and spray guns use this principle to generate suction.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The conversion mechanism of pressure. When resources or time are compressed (entering a narrow pipe), don't just feel the pressure. Use the low-pressure zone (suction) created by the increased flow velocity to draw in external resources or stimulate explosive power. A bottleneck is not only a limitation, but also an accelerator.

Anchor fast decisions

When a fluid passes through a contraction section, the flow velocity increases and the static pressure decreases (Bernoulli's principle), forming a negative pressure that can be used for suction. It converts velocity changes into pressure differences.

Viscosity

In continuum mechanics, viscosity is a property of a fluid that quantifies the resistance force acting on fluids when there is relative motion between fluid parcels. This resistance force is caused by

The Magnus Effect

The Magnus effect, named after its discoverer Heinrich Magnus, is a phenomenon in fluid mechanics where a rotating object (such as a cylinder) moving through a fluid experiences a force.

Thixotropy

Thixotropy is a property of certain non-Newtonian fluids that become fluid when stirred, and gradually thicken and gel when stirring stops, rather than immediately returning to their pre-stirred state. This process can be repeated reversibly. Thixotropy is also a phenomenon of reversible transformation of fluid structure, namely the gel-sol-gel transition, which is caused by temperature, pH, or other influencing factors.
