Sentences with phrase «mean free path distribution»

For example, if an engineer desires a material with certain thermal properties, the mean free path distribution could serve as a blueprint to design specific «scattering centers» within the material — locations that prompt phonon collisions, in turn scattering heat propagation, leading to reduced heat carrying ability.

Not exact matches

For each material, the researchers plotted a distribution of mean free paths, reconstructed from the heater - size - dependent thermal conductivity of a material.

The simplest things one can do microscopically are things like detailed balance estimates, and so far I haven't made Joe happy even with what I've attempted there, although I think he realizes that my answer is irrelevantly imprecise (or he should realize it once he follows the reasoning in the algebra above that lays out how air can be isothermal and still have the MB velocity distribution from the bottom out to where the assumptions of thermodynamics break down anyway, because to many, many digits when meters is the mean free path of the gas and meters.
