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.
