In this paper, the curves of an ideal gas, ideal enthalpy, and ideal internal energy, united by a common definition of classical ideal curves (CICs), are considered. It is shown that the configurational parts of the thermodynamic properties, such as enthalpy H , internal energy U, PV , ...
The effect of nonlinearity of the equilibrium enthalpy was considered by using an enthalpy correction factor in the effectiveness definition only for the cases with smaller air flow heat capacity rate. However, the derivation of this correction factor is not convincing. The model does not consider ...

The new density can be calculated using an equation of state (EOS) as ρ=ρ(p,h). the local sound speed, total enthalpy and internal energy can be renewed using current values of pressure, density and velocity: (35)C=γp∕ρ,H=cpT+ui2∕2,E=H−p∕ρ At this stage, other ...

where K≡|u|2/2 is kinetic energy per unit mass and the enthalpy per unit mass h is the sum of the internal energy per unit mass e and the kinematic pressure h≡e+p/ρ. We can get the following relations from this definition: ∂(ρe)∂t=∂(ρh)∂t−∂p∂t,∇⋅...
(commonly assumed in compressor and turbine analyses; NOT in nozzle and diffuser), the rate of work input will be directly related to – the mass flow rate; – change in enthalpy • Based on the above result, the change in enthalpy between the inlet and outlet state in a compressor or...
And then from the definition of B we have $$ B=4\sigma {T}^3/\left(0.75\tau +1\right) $$ (E.14.24) We can now determine the value for D maximizing the entropy production. Subtracting (E.14.15) we have $$ {I}_0-{I}_1-B\left({T}_0-{T}_1\right)=2F=4D\varDelta...

To compare results from SC and DC simulations in order to provide information to balance their largely different computational costs as well...
