8.1. Introduction

The starting point of the computation of the friction drag coefficient are the partial differential equations (PDEs) of the Navier-Stokes layer (NSL), given in [1] and [2] without any simplification.

In this chapter is presented a further application of the original, zonal, spectral solutions for the compressible stationary NSL over flattened flying configurations (FCs) presented in Chap. 1 and in ...
