Agrira, Abdalla and Buttsworth, David R. and Yusaf, Talal (2009) Instantaneous heat flux simulation of S.I. engines: comparison of unsteady thermal boundary layer modelling with experimental data. In: 3rd International Conference on Energy and Environment: Advancement Towards Global Sustainability (ICEE 2009), 7-8 Dec 2009, Malacca, Malaysia.
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.
