High Speed Aerodynamics 03: Linearized Potential Equation and Subsonic Transformations

This section shows how the potential equation is simplified for the case of small perturbations, and the assumptions implied in linearizing the equation. The linearized equations are no longer general to all compressible potential flow, but are limited to specific regimes of Mach number. In the subsonic regime, the linearized equation can be transformed to the Laplace equation by transforming the coordinate system. This transformation approach is then used to get results for subsonic Mach numbers using the idea of a "corresponding incompressible flow problem". Please click to download pdf notes.
