function x = FlowDevice(typ)

% FLOWDEVICE FlowDevice class constructor.

|
% x = FlowDevice(typ)
|
|
% Base class for devices that allow flow between reactors.
|
|
% :mat:func:`FlowDevice` objects are assumed to be adiabatic,
|
|
% non-reactive, and have negligible internal volume, so that they are
|
|
% internally always in steady-state even if the upstream and downstream
|
|
% reactors are not. The fluid enthalpy, chemical composition, and mass
|
|
% flow rate are constant across a :mat:func:`FlowDevice`, and the
|
|
% pressure difference equals the difference in pressure between the
|
|
% upstream and downstream reactors.
|
|

|
|
% See also: :mat:func:`MassFlowController`, :mat:func:`Valve`

% :param typ:

% Type of :mat:func:`FlowDevice` to be created. ``typ=1`` for
|
|
% :mat:func:`MassFlowController` and ``typ=3`` for

|
% :mat:func:`Valve`
