Inviscid flow Euler’s equations of motion

Uniform Flow and a Source. Let us now place a source in the path of a uniform flow. The stream function and the velocity potential for the resulting flow are given by adding the two stream functions and velocity potentials as follows, (4. 89) (4. 90) One of the interesting features to determine for the resulting force is the stagnation point of the flow, i.e., where the velocity goes to zero.

CBE 6333, R. Levicky 6 Functions that obey Laplace's equation are called "harmonic" functions. Therefore, under these conditions both the stream function and the velocity potential are harmonic.

The quantity in parentheses is at most a function of time !"!t + P # + UiU 2 =f(t) (10.10) The expression (10.10) is called the Bernoulli integral and can be used to determine the pressure throughout the flow once the velocity potential is known from a solution of Laplaces equation (10.7). Generally the flow is specified within a volume V surrounded by surface A(Figure 10.1). A solid body

Stream function (?) Potential function (? ) Why Use Potential Flow? Potential flows helps to simplify complex flow situations so that a good approximate solution can be found As potential flow represents an idealized flow solution it does not exist in real flows Most CFD (Computational Fluid Dynamics) solvers use potential flow theory to approximate the flow solution outside

namely, the potential and stream function analysis. As will be seen later, this technique is especially useful when the equation cannot be separated in its original coordinates. 2. POTENTIAL AND STREAM FUNCTIONS It is well-known in fluid dynamics that in incompressible, irrotational flow the fluid velocity is non-divergent and can be derived from a scalar potential 4 which satisfies equation
