Aerodynamic Heating

Heat Transfer at High Speeds

Abstract

A physical description of aerodynamic heating is presented. The theory is presented for a flat plate boundary layer flow, and important parameters such as adiabatic wall temperature and recovery factor are introduced. A method to calculate the heat flux is outlined. A simple illustrative numerical example is described. An engineering practical system is analyzed.

3.1. Introduction

In many engineering applications, it may be assumed that the influence on the energy balance by the work of the viscous forces is negligible. As the flow velocity becomes sufficiently high, this assumption ...
