Euler equations (fluid dynamics)
<a href="https://en.wikipedia.org/wiki/Euler_equations_(fluid_dynamics)" rel="nofollow">https://en.wikipedia.org/wiki/Euler_equations_(fluid_dynamic...</a><p>> <i>In fluid dynamics, the Euler equations are a set of quasilinear partial differential equations governing adiabatic and inviscid flow. They are named after Leonhard Euler.</i> In particular, they correspond to the Navier–Stokes equations with zero viscosity and zero thermal conductivity. [1]<p>Navier–Stokes equations

<a href="https://en.wikipedia.org/wiki/Quantum_fluid" rel="nofollow">https://en.wikipedia.org/wiki/Quantum_fluid</a><p>> <i>Quantum mechanical effects become significant for physics in the range of the de Broglie wavelength. For condensed matter, this is when the de Broglie wavelength of a particle is greater than the spacing between the particles in the</i> lattice <i>that comprises the matter.</i> [...]<p>> <i>The above temperature limit T has different meaning depending on the quantum statistics followed by each system, but generally refers to the point at which the system manifests quantum fluid properties. For a system of fermions, T is an estimation of the Fermi energy of the system, where processes important to phenomena such as superconductivity take place. For bosons, T gives an estimation of the Bose-Einstein condensation temperature.</i><p>Classical fluid <a href="https://en.wikipedia.org/wiki/Classical_fluid" rel="nofollow">https://en.wikipedia.org/wiki/Classical_fluid</a><p>> <i>Classical fluids [1] are systems of particles which retain</i> a definite volume, <i>and are at sufficiently high temperatures (compared to their Fermi energy) that quantum effects can be neglected</i> [...] <i>Common liquids, e.g., liquid air, gasoline etc., are essentially mixtures of classical fluids. Electrolytes, molten salts, salts dissolved in water, are classical charged fluids. A classical fluid when cooled undergoes a freezing transition. On heating it undergoes an evaporation transition and becomes a classical gas that obeys Boltzmann statistics.</i><p>Chaos theory <a href="https://en.wikipedia.org/wiki/Chaos_theory" rel="nofollow">https://en.wikipedia.org/wiki/Chaos_theory</a><p>> <i>Chaos theory is [...] focused on underlying patterns and deterministic laws highly sensitive to initial conditions in dynamical systems that were thought to have completely random states of disorder and irregularities. [1] Chaos theory states that within the apparent randomness of chaotic complex systems, there are underlying patterns, interconnectedness, constant feedback loops, repetition, self-similarity, fractals, and self-organization.</i><p>Quantum chaos
