Web4 jun. 1998 · The Umbral algebra developed by Rota and his co‐workers is used to show that the Mayer cluster expansion of the canonical partition function is related to the Bell polynomials. The algebra is also used to find a representation of the partition function and a rederivation of Mayer’s first theorem. Finally, it is shown that in the ’’tree approximation’’ … WebStream Function Definition Consider defining the components of the 2-D mass flux vector ρV~ as the partial derivatives of a scalar stream function, denoted by ψ¯(x,y): ρu = ∂ψ¯ ∂y, ρv = − ∂ψ¯ ∂x For low speed flows, ρis just a known constant, and it is more convenient to work with a scaled stream function ψ(x,y) = ψ¯ ρ
