Reliable and accurate combustor modeling is a key element for scramjet vehicle design. Especially in
the early design and concept phase this requires a fast, adaptable, and robust model. This paper
presents a straightforward approach to model such scramjet combustors on a discrete one-dimensional
mesh by serializing the different flow and combustion processes in individual cells. This way the
implementation effort is significantly decreased while the numerical stability is increased in comparison
to more common finite-difference modeling. Additionally, it allows direct implementation of correction
terms and empirical factors fitting the model to detailed numerical simulations or experimental data.
