Theoretical analysis of quantum turbulence using the Onsager ideal turbulence theory

نویسندگان

چکیده

We investigate three-dimensional quantum turbulence as described by the Gross-Pitaevskii model using analytical method exploited in Onsager "ideal turbulence" theory. derive scale-independence of scale-to-scale kinetic energy flux and establish a double-cascade scenario: at scales much larger than mean intervortex $\ell_i$, Richardson cascade becomes dominant, whereas smaller another type is induced stress. then evaluate corresponding velocity power spectrum phenomenological argument. The relation between novel cascade, which we call stress Kelvin-wave also discussed.

Onsager and the theory of hydrodynamic turbulence

Lars Onsager, a giant of twentieth-century science and the 1968 Nobel Laureate in Chemistry, made deep contributions to several areas of physics and chemistry. Perhaps less well known is his ground-breaking work and lifelong interest in the subject of hydrodynamic turbulence. He wrote two papers on the subject in the 1940s, one of them just a short abstract. Unbeknownst to Onsager, one of his m...

Estimate the Performance of Catalytic Converter Using Turbulence Induce Devices

In this manuscript, the experimental setup was designed and fabricated for optimizing the parameters of a catalytic converter of INDICA V2 exhaust system. Three turbulence intensify devices, namely Swirl Venturi, Swirl Blades and Swirl Contour, were close-fitted before the catalytic converter. The heating element is embedded in its body and thermocouples are used for knowing the performance at ...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Averaged equations of ideal fluid turbulence

A system of equations for averaged velocity of turbulent motion of ideal fluid is derived from the assumption that this motion is ergodic. Several fluid flows are considered. A remarkable feature of the averaged equations is that in some cases they have a form of an eigenvalue problem similar to that for Schrődinger’s equation. The equations derived suggest that there are no universal equations...

Quantum Turbulence Decay

We develop a computational model of quantum turbulence decay employing a kinematic prescription for the normal fluid. We find that after an initial transient, the length of the vortex tangle L decreases and for large times obeys the scaling law L ≈ t−0.45. The average magnitude (along the quantized vortices) of the superfluid and line-vortex velocity are close and differ significantly from the ...
