Three-Dimensional Incompressible Flow topics include: Flow over sphere, three dimensional source, three dimensional doublet and three dimensional flow panel techniques. Three-dimensional incompressible flow is a flow where the velocity is a function of time and three space coordinates.  The general equation of continuity for three-dimensional flow of an incompressible fluid of steady flow is: ∂ u ∂ x + ∂ v ∂ y + ∂ w ∂ z = 0  The velocity components in the y and z-directions are:  v = ax^3 - by^2 + cz^2 w = bx^3 - cy^2 + az^2  Some examples of three-dimensional flow include: Flow in a...
