and Real Fluid Effect under Planer Sluice Gate.
Covering first irrotational flow
motion of an ideal fluid, then the theory and applications of real fluid flows, he discusses such topics as ideal fluid flows and irrotational flow
motion; basic equations and flow analogies for two-dimensional flows; Joukowski transformation, the theorem of Kutta-Jourkowski, and lift force on an airfoil; and turbulence, and applying boundary layer theory to laminar boundary layer flows.
According to Green theorem, the perturbation velocity potential [PHI](t) in inviscid, incompressible, and irrotational flow
with non-uniform velocity V(x, y, z,t) of an arbitrary field point P(x, y, z,t) can be expressed as an integral on the boundary surface of flow field S, which is composed of flapping hydrofoil surface [S.
2] = constant, is associated with irrotational flow
in (nearly) inviscid fluids (Chorin and Marsden 1993).
6% was slipping irrotational flow
, obtaining the calculated [Delta] values (8th row, Table 1).
