* add deprecation warning for int ReactorBase::type() (to be changed after Cantera 2.5) * introduce temporary std::string ReactorBase::typeStr() (to be renamed after Cantera 2.5) * deprecate all functions using the old call and introduce associated temporary functions

function v = Valve(upstream, downstream)
|
|
% VALVE Create a valve.
|
|
% v = Valve(upstream, downstream)
|
|
% Create an instance of class :mat:func:`FlowDevice` configured to
|
|
% simulate a valve that produces a flow rate proportional to the
|
|
% pressure difference between the upstream and downstream reactors.
|
|
%
|
|
% The mass flow rate [kg/s] is computed from the expression
|
|
%
|
|
% .. math:: \dot{m} = K(P_{upstream} - P_{downstream})
|
|
%
|
|
% as long as this produces a positive value. If this expression is
|
|
% negative, zero is returned. Therefore, the :mat:func:`Valve` object
|
|
% acts as a check valve - flow is always from the upstream reactor to
|
|
% the downstream one. Note: as currently implemented, the Valve object
|
|
% does not model real valve characteristics - in particular, it
|
|
% does not model choked flow. The mass flow rate is always assumed
|
|
% to be linearly proportional to the pressure difference, no matter how
|
|
% large the pressure difference. THIS MAY CHANGE IN A FUTURE
|
|
% RELEASE.
