8) is a integral for determining the potential [PHI] on the flapping hydrofoil surface SB and the normal derivative
[partial derivative]/[partial derivative][n.
Note that [partial derivative][OMEGA] is part of the interface because the boundary condition for the normal derivative is only enforced weakly through the penalty term in (1.
h]([OMEGA] [GAMMA]) if and only if v and its normal derivative vanish on [GAMMA].

At the outlet, the uniform axial velocity was used to ensure continuity, and tangential velocities were computed from a zero normal derivative
m, i] and can have nonzero trace of the normal derivative onto [[gamma].
k] the values of normal derivative at the midpoints of [[[delta].
where [DELTA] denotes the Laplacian operator and [partial derivative]/[partial derivative]v is the normal derivative
at the boundary of [OMEGA].
j] to be the function whose normal derivative
at p is 1 and takes the value zero for all other nodal variables, and (iii) [[delta].
The book is unique for its presentation of a new theory for the tangential and normal derivatives
of flow properties (such as pressure and velocity) just downstream of an infinitesimally thin, curved shock wave.
They exhibited significant differences only in the immediate proximity of the aperture, but in this region their physical properties were obscured by the fact that they or their normal derivatives
, or both, do not reproduce the assumed incident field.
The Kirchhoff and Rayleigh-Sommerfeld integral equations (1) and (2) are alternative forms of the theorem of Helmholtz (5), which expresses Huygens' principle in terms of a scalar wave function U and its normal derivatives
without assuming specific attributes of this function, except that it is continuous and twice differentiable with continuous derivatives and obeys the homogeneous wave equation,
