Thermal levitation | Journal of Fluid Mechanics | Cambridge Core
2008年7月10日 · When the terminal velocity is zero we say there is thermal levitation. Thermal levitation can also occur when the density and temperature of the particle are smaller than those of the fluid. Using a two-component thermal lattice Boltzmann equation method, we study this phenomenon and show it can be stable or unstable.
Thermo-fluid-dynamics of inverse Leidenfrost levitation of small …
2023年4月7日 · The present study provides a detailed theoretical investigation of the thermo-fluid-dynamics of the inverse Leidenfrost levitation phenomenon of a microscale droplet/solid on a liquid pool, and also the conditions essential for solid/liquid spherical objects to levitate.

Numerical study of the relation between the thermal effect and …
2013年4月15日 · In this paper we present a numerical analysis of dynamic features of the levitation system generated by an interaction between a levitated permanent magnet (PM) and a high-Tc superconductor (HTSC) excited by an oscillatory external source where the thermal effect inside the superconductor is taken into account in a macro-model of superconductivity.
Thermal levitation can lift any object in the air, unlike other …
2017年2月17日 · Now, a novel levitation technique developed at the University of Chicago can lift particles of virtually any nature. The method works by exploiting temperature differences.

Transient Thermal Characterization of Small Particles in Fluidic or ...
Analysis of the thermal behavior of small particles in levitation in a gas makes it possible to study chemical or phase transformations without polluting contact with a solid support. The small size of the particle, with a large exchange surface compared to the volume, makes it possible to assume that the particle is isothermal with very fast ...
