ABSTRACT

The Euler equations are readily obtained from the governing equations of Chapter 2 by setting

(

5.1

)

The resulting equations represent an inviscid, adiabatic flow. Usually, the flow is simply referred to as inviscid because

κ

and

µ

are not independent parameters but are related by the Prandtl number

(

5.2

)

where

Pr

is finite and positive. The assumption of

µ

= 0 therefore implies

κ

= 0 and vice versa. It is useful to note that an adiabatic flow is generally not isothermal, and vice versa.
