These changes make it unnecessary to copy header files around during the build process, which tends to confuse IDEs and debuggers. The headers which comprise Cantera's external C++ interface are now in the 'include' directory. All of the samples and demos are now in the 'samples' subdirectory.

% VALVE - Create a valve connecting two reactors / reservoirs.
|
|
%
|
|
% m = Valve(upstream, downstream)
|
|
%
|
|
% creates an instance of class FlowDevice configured to simulate a
|
|
% valve that produces a flow rate proportional to the pressure
|
|
% difference between the uupstream and downstream reactors. If two reactor
|
|
% objects are supplied as arguments, the valve is installed
|
|
% between the two reactors.
|
|
%
|
|
% The mass flow rate [kg/s] is computed from the expression
|
|
%
|
|
% mdot = K ( P_upstream - P_downstream )
|
|
%
|
|
% as long as this produces a positive value. If this expression is
|
|
% negative, zero is returned. Therefore, the 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 mass flow rate, no matter how
|
|
% large the pressure difference. THIS MAY CHANGE IN A FUTURE
|
|
% RELEASE.
