Discretization of Potential Flow Equation
The potential flow equation with well-posed boundary conditions applied is:
- Note that the integration term is evaluated only on the upper surface, while th integral term is evaluated on the upper and lower surfaces.
The continuous surface S may now be discretized into discrete panels. These panels will approximate the shape of the actual surface. This value of the various source and doublet terms may be evaluated at a convenient point (such as the centroid of the panel). Some assumed distribution of the source and doublet strengths (typically constant or linear) are used at points other than the centroid. A single source term s of unknown strength and a single doublet term m of unknown strength are defined at a given point.
where:
These terms can be used to create a system of linear equations which can be solved for all the unknown values of .

Famous quotes containing the words potential, flow and/or equation:
“And what is the potential man, after all? Is he not the sum of all that is human? Divine, in other words?”
—Henry Miller (1891–1980)
“And if blood of Martyrs is to flow on the steps
We must first build the steps;
And if the Temple is to be cast down
We must first build the Temple.”
—T.S. (Thomas Stearns)
“Jail sentences have many functions, but one is surely to send a message about what our society abhors and what it values. This week, the equation was twofold: female infidelity twice as bad as male abuse, the life of a woman half as valuable as that of a man. The killing of the woman taken in adultery has a long history and survives today in many cultures. One of those is our own.”
—Anna Quindlen (b. 1952)
