Rayleigh range meaning
WebRayleigh damping does afford certain mathematical conveniences and is widely used to model internal structural damping. ... If your system response is concentrated at the wave frequency for all critical design cases, rather than across a range of frequencies, then it is safe to apply stiffness proportional damping. WebMay 22, 2024 · Prandtl Number of Liquid Metals. For liquid metals the Prandtl number is very small, generally in the range from 0.01 to 0.001. This means that the thermal diffusivity, which is related to the rate of heat transfer by conduction, unambiguously dominates.This very high thermal diffusivity results from very high thermal conductivity of metals, which is …
