The two fluids are chemically identical and
represented
by the phase-change model. Example:
Liquid water and steam are mixed in a steady-flow mixing chamber to
produce
hot water. A steady flow of refrigerant is separated into flows of
saturated
vapor and saturated liquid in a separation chamber.
SL Model
Constant density
and
constant specific heats
(c_p=c_v=c)
characterize the pure solid or liquid model. The
two substances, A and B, are identical. Example:
Oil at two different states are mixed in a steady-flow mixing
chamber
with no possibility of a phase change.
Gases:
PG Model
Constant density
and
constant specific heats
(c_p=c_v=c)
characterize the pure solid or liquid model. The
two gases, A and B, are identical. Example:
CO2 at two different states are mixed in a steady-flow mixing
chamber
with no possibility of a phase change.
IG Model
Obeys the ideal
gas equation
(pv=RT). Specific heats are temperature dependent. The
two gases, A and B, are identical. Example:
CO2 at two different states are mixed in a steady-flow mixing
chamber
with no possibility of a phase change.
RG Model
Based on the generalized compressibility
chart (pv=ZRT), the real gas model can handle a large
number
of
fluids in their liquid, vapor or gaseous states. The
two gases, A and B, are identical. Example:
Propane
at two different states are mixed in a steady-flow mixing
chamber
with the possibility of a phase change.
Two Different
Gases:
PG+PG
Model
IG+IG
Model
RG+RG
Model
The two gases, A and
B, can be chemically
different. Example:
O2 and N2 are mixed in a steady-flow mixing chamber.
Specific Closed Process and Its Governing Balance Equations
System
Animation of a mutli-flow, mixing, open steady system having all possible interactions with its surroundings. The mixing daemons also allow separation of flows (as in a flash chamber or a turbine with bleeding). For specific examples of multi-flow, mixing, open steady systems, visit TEST.VT.Chapter-4 pages.
