Building a Fast Running Engine Model (FRM)   9.1 Introduction Fast Running Engine Models are dynamic, fully-physical engine models that are designed specifically to run fast. While high-fidelity engine models are commonplace in the engine performance department, they are often too slow running to incorporate into…

1. Single turboThe simplest, and still most common, type of turbo is the single-turbocharger set-up. Because of its relative simplicity (compared to the other options on this list), it is the cheapest, but arguably not the best, turbo option available. A single turbocharger can’t be effective across the whole rev…

FINITE VOLUME METHOD: The Finite Volume Method (FVM) is one of the most versatile discretization techniques used in CFD. Based on the control volume formulation of analytical fluid dynamics, the first step in the FVM is to divide the domain into a number of control volumes (aka cells, elements) where the variable of interest…
