nodes
A = mysimscape.thermohydraulic.thermohydraulics; % A:right
B = mysimscape.thermohydraulic.thermohydraulics; % B:right
C = mysimscape.thermohydraulic.thermohydraulics; % C:left
end
parameters
density = {1000, 'kg/m^3'};
cp = {4.19, 'kJ/(kg*K)'};
end
variables(Access = protected)
qf1 = { 0 ,'m^3/s' }; % Flow rate 1
qf2 = { 0 ,'m^3/s' }; % Flow rate 2
qf3 = { 0 ,'m^3/s' }; % Flow rate 3
Phi1 = { 0, 'kW'};
Phi2 = { 0, 'kW'};
Phi3 = { 0, 'kW'};
end
branches
qf1 : A.qf -> *;
qf2 : B.qf -> *;
qf3 : C.qf -> *;
end
equations
% No pressure drop
A.p == C.p;
% B.p == C.p;
% Energy flow equations
Phi1 == qf1 * density * cp * A.t;
Phi2 == qf2 * density * cp * B.t;
Phi3 == qf3 * density * cp * C.t;
% Energy conservation
Phi1 + Phi2 + Phi3 == 0;
% Mass conservation
qf1 + qf2 + qf3 == 0;
end
end
Is this code correct? My domain is a customised thermohydraulic domain that includes variables p, t and q.
