Due to the inherently unsteady environment of the internal combustion engine, unsteady thermal boundary layer modelling could make a useful contribution. Instantaneous heat flux in a spark ignition internal combustion engine was predicted using a quasi-one dimensional engine cycle simulation program developed in Matlab. Simulation parameters were tuned within reasonable limits until good agreement between the simulated and measured pressure was achieved. To some degree, the heat flux simulated using Annand’s model agreed with the experimental data, particularly with respect to the averaging process over the unburned and burned zones. However, no such agreement was found when the unsteady thermal boundary layer model was applied. Implementing a model for turbulent thermal conductivity in the unsteady thermal boundary layer simulation is expected to improve the simulation.
