TABLE OF CONTENTS In Part 2, we emphasize the effects of viscosity and thermal conduction in combination with high Mach numbers, and we will label such flows as hypersonic viscous flow. The effects of high temperature and diffusion will be covered in Part 3. In dealing with inviscid hypersonic flow in Part 1, we examined the question: What happens to the fluid dynamics of an inviscid flow when the Mach number is made very large? In Part 2 we take the next logical step and address the question: What happens in a high-Mach-number flow when the transport phenomena of viscosity and thermal conduction are included? The answer to this question leads to many practical results regarding the prediction of skin friction and aerodynamic heating in hypersonic flow.
Two major problems encountered today in aeronautics are the determination of skin friction and skin temperatures of high-speed aircraft.

With this chapter we leave the ideal world of inviscid flow and enter the real world of viscous flow. What physical phenomena determine the skin-friction drag and aerodynamic heating of hypersonic vehicles? We will find out here. How can we calculate the skin-friction drag and aerodynamic heating of hypersonic vehicles? We will find out here. If you are a practical person looking for practical methods to deal with skin-friction drag and aerodynamic...
