fluidisoituvan

Fluidisoituvan is a term used in speculative materials science to denote a transitional state in which a granular or soft particulate system acquires fluid-like properties in response to external energy input or fluidizing agents. The concept sits at the intersection of fluidization and jamming theory, describing a controlled shift from a solid-like, rigid network to a flowing, rearranging ensemble of particles.

Definition and features: It describes a regime where interparticle contacts yield under applied stress, causing bed expansion, increased particle mobility, and a viscosity that varies with shear rate. The fluidisoituvan regime exhibits non-Newtonian behavior, with possible shear-rate dependent viscosity, localized flow structures, channeling, and intermittent bursts. The transition is typically framed as being reversible under changes in energy input or confinement.

Origin and status: The term originated in theoretical discussions and thought experiments around the 21st century and is not part of standard terminology in established journals. Its usage is limited and often treated as a speculative model rather than an empirically validated phase, with most examples arising from simulations or conceptual analyses rather than systematic experiments.

Relation to other ideas and potential applications: It relates to classical fluidization, granular flows, and non-Newtonian fluid models. If realized, the concept could inform the design of mixing protocols, hopper flow control, and additive manufacturing processes where controlled fluid-like behavior is advantageous. However, concrete demonstrations remain limited and the term remains primarily in theoretical or exploratory contexts.
