WebApr 12, 2024 · The arrow is black when the orientation is significant (p < 0.05), as in the larvae from the Control group (Rayleigh’s test of uniformity, mean bearing in situ = 327°, r = 0.33, p = 0.006). The Rayleigh number describes the behaviour of fluids (such as water or air) when the mass density of the fluid is non-uniform. The mass density differences are usually caused by temperature differences. Typically a fluid expands and becomes less dense as it is heated. Gravity causes denser parts of the fluid to sink, which is called convection. Lord Rayleigh studied the case of Rayleigh-Bénard convection. When the Rayleigh number, Ra, is below a critical value for a fluid… easter cooking for children
