CORE DEFINITION

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.

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.

Anchor fast decisions

When a rotating object moves through a fluid, the difference in flow velocity on its two sides creates a lateral pressure difference, resulting in a lift force perpendicular to the direction of motion. This is the Magnus effect, a manifestation of Bernoulli's principle applied to rotating bodies.

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

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.

Coanda Effect

The Coandă effect ( or ) is the tendency of a fluid jet to stay attached to a surface of any form. Merriam-Webster describes it as "the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lowe…
