The phrase "thermodynamic modeling of engines" probably refers to the (very simplified) zero-dimensional modeling of the steady flow through engines by quasi-equilibrium thermodynamic processes. It basically comes down to what you study in applied thermodynamics as "cycle analysis of heat engines", wherein each component of the engine (compressor, combustor, turbine, ...) is modeled as a process on a p-v or T-s or h-s chart of the working fluid, with experimentally estimated efficiencies to account for real-world losses. For complex systems, consisting of many components linked together, this kind of model is an essential first step to understanding (and optimizing) the system performance, and to more detailed (unsteady or 1D spatial, or eventually 3D unsteady) modeling.
