Abstract

To calculate the aerodynamic forces and moments acting on a flying vehicle, it is imperative to describe the flow pattern around the vehicle. The flow pattern thus obtained depends on the geometry of the vehicle, its orientation with respect to the oncoming freestream, altitude, and flying speed. Often, these patterns are very complex which necessitates to carry out both the experimental and theoretical studies to characterize the resultant flow. Moreover, the theoretical studies may utilize simplifying approximations in order to obtain any solution at all, and they must be matched with experimental data. Therefore, we must understand the fundamental laws that govern the fluid flow phenomena so that we can relate the theoretical results with experimental observations.
