Exhaust Gas Recirculation (EGR) is one of several technologies that are being investigated to deliver future legislative emissions targets for diesel engines. Its application requires a detailed understanding of the thermofluidic processes within the engine's charge air system. A fully validated Computational Fluid Dynamics (CFD) process is one way of providing this understanding. This thesis describes how a process was developed using validation data from a four-branch diesel engine inlet manifold with a secondary EGR inlet. The validation and verification technique adopted, divided the complex flow problem into simpler elemental flow problems. Knowledge on these simple problems was, in some cases, found to be well documented in published literature. In other cases, additional detailed experimental validation and verification studies were carried out to supplement published information. Knowledge from these simple problems was utilised to develop the main CFD process and to enhance understanding of the calculation uncertainties......
