It is assumed that the volume is high enough regarding the flow at boundaries to consider a zero velocity in the volume. Indeed, all the kinetic energy from boundaries is instantanetly dissipated to heat.
First, the Total properties derives from the medium class herited from the BasesProperties model of the Medium package.
Where:
m is the mass contains in the gas node medium.d is the density of the medium in the gas node V is the geometrical volume of the gas node U is the total internal energy in the gas node medium.u is the specific internal energy of the medium in the gas node mXi is the vector of independent mass of each species in the gas node medium.Xi is the vector of independent mass fraction of each species of the medium in the gas node mC is the vector of independent mass of each traces species in the gas node c is the vector of independent mass concentration of each traces species of the medium in the gas node The dynamic behavior of the total properties derives from the first principe of thermodynamics for the energy balance and from the mass conservation for the mass balance. The balance is performed from boundaries (ports):
Where:
m_flow is the net mass flow rate coming of leaving the gas node from the mass flow rate balance between all the portsmXi_flow is the vector of net independent mass flow rate coming of leaving the gas node from the mass flow rate balance between all the portsQ_flow is the net heat flow rate through the frontiers of the gas node from the heat flow rate balance of the heatPortH_flow is the net enthalpy flow rate from the balance between the entering and leaving enthalpy transported by the mass flow rate at boundaries | Name | Description |
