# Mixer

A mixer mixes two input material streams (In1, In2) into the one output stream (Out), as shown in the scheme below.

The output stream will be defined for all time points for which the streams In1 and In2 are defined. Mixing of more streams can be implemented by connecting of several mixers sequentially.

The parameters of output stream are calculated as:

\dot{m}_{out} &= \dot{m}_{in1} + \dot{m}_{in2} \dot{H}_{out} &= \dot{H}_{in1} + \dot{H}_{in2} T_{out} &= f(h_{out}) = f \left( \frac{\dot{H}_{out}}{\dot{m}_{out}} \right) P_{out} &= min( P_{in1},P_{in2} )

Note

Notations:

\dot{m} – mass flow

\dot{H} - enthalpy flow

h - specific enthalpy

T - temperature

P - pressure

All secondary attributes of output stream, such as phase fractions, compounds fractions and multidimensional distributions are calculated depending on mass fractions of input streams.
