fluidbased

Fluidbased is a broad term used to describe systems, processes, and devices in which the behavior of liquids and fluid flows plays a central role. It encompasses designs, materials, and theories that treat fluids as the primary medium or agent of action, rather than solids alone.

The concept sits at the intersection of physics and engineering, drawing on fluid dynamics, rheology, and multiphase flow. Core ideas include the conservation of mass, momentum, and energy; the governing Navier–Stokes equations; and factors such as viscosity, surface tension, capillarity, and the distinction between turbulent and laminar regimes. Fluidbased applications commonly appear in microfluidics, hydraulic systems, lubrication, cooling technologies, and soft robotics, where fluids mediate actuation, sensing, or heat transfer.

In microfluidics, fluidbased approaches enable lab-on-a-chip devices, biomedical assays, and chemical synthesis in compact formats. In engineering contexts, fluid-based cooling systems, lubricants, and hydraulic actuators rely on controlled fluid flow to transfer energy and manage temperature. In soft robotics and bio-inspired engineering, fluids can power compliant actuators and provide adaptable motion characteristics, expanding the range of achievable tasks.

Research areas within fluidbased include controlling multiphase flows, turbulence management, fluid–structure interaction, and fluid transport in porous media. Practical challenges involve measurement at small scales, materials compatibility, and non-Newtonian fluid behavior, which can complicate modeling and control.
