WebThe ratio Ra / Pr is also called the Grashof number Gr =α g Δ Tnaa3 /ν 2 (Grashof, 1826–1893). This number can also be written as V0a /ν and could be called the Reynolds number, Re, of the flow (Reynolds, 1842–1912). Using one or the other names depends on the quantities that are best known. For example, if the velocity V is a parameter ...

WebApr 11, 2024 · At high values of the Grashof and Prandtl numbers, this analysis suggests a linear relationship between Nu avg and Ω CWT. The constant of proportionality is a weak function of the flow behaviour index (n). The value of this constant ranges from ∼ 0.64 at n = 0.2 to ∼ 0.66 at n =1. Thus, it is reasonable to use a mean value of ∼ 0.65.
