Isentropic Flow

in this lecture discussion of steady
state ?ow though a smooth and con-
tinuous area ?ow rate (steady state) is
presented. A discussion about the ?ow
through a converging–diverging nozzle
is also part of this Chapter. The isen-
tropic ?ow models are important be-
cause two main reasons: one, it pro-
vides the information about the trends
and important parameters, two, the cor-
rection factors later can be introduced
to account for deviations from the ideal
state.
It is assumed that the ?ow is one–dimensional. Figure shown describes a gas ?ows
through a converging–diverging nozzle.t has been found that a theoretical state
known as the stagnation state is very useful in simplifying the solution and treat-
ment of the ?ow. he stagnation state is a theoretical state in which the ?ow is
brought into a complete motionless condition in isentropic process without other
forces (e.g. gravity force). Several properties that can be represented by this the-
oretical process which include temperature, pressure, and density .
