    A gas turbine engine is an advanced apparatus for propulsion and power generation that has been developed over the last 60 years. The energy for this production of propulsion and power in a gas turbine is generated by combustion. It is feasible and relatively easy to solve the governing equations in combustion for one dimensional laminar hydrocarbon combustion with detailed chemistry. This has been done for several hydrocarbon fuels that are representative for liquid fuel combustion. The complex chemistry that is solved completely in a laminar flame is mostly modelled in simulations of turbulent combustion. Essential to this modelling is a correct understanding of the processes that govern the chemistry. Via the route of a numerical perturbation method, the CSP-method, this understanding can be developed. After analysis with CSP, the next step to a model describing turbulent combustion in gas turbines is taken using the CFI combustion model. This model comprises the definition of a reaction progress variable representing the reduced chemistry yielding from CSP, a mixture fraction variable and an enthalpy variable. The thesis presents a version of the CFI combustion model for application in evaporating fuel sprays.
