Rayleigh temperature
WebMay 22, 2024 · The Rayleigh number is defined as: where: g is acceleration due to Earth’s gravity. β is the coefficient of thermal expansion. T wall is the wall temperature. T ∞ is the bulk temperature. L is the vertical length. α is thermal diffusivity. ν is the kinematic viscosity. For gases β = 1/T where the temperature is in K. WebDuring processing, these give rise to a strong coupling between the induced stress and temperature gradients affecting final properties of the material. In our laboratory, we have investigated anisotropic thermal conductivity in polymers subjected to deformation using an optical technique based on Forced Rayleigh Scattering (FRS).
