Double the air pressure in the intake, and you almost double the power available without changing the engine displacement. Whether you’re trying to squeeze more torque from a racing car, or you’re trying to use a smaller engine to do the job of a bigger one for overall fuel efficiency, the reasons for turbocharging a gas or diesel engine are compelling.
The engineering challenges can also be compelling. Designing a turbocharger that matches well to a particular engine over requisite drive cycles (for automotive applications) or duty cycles (for industrial engines) is an extremely difficult task. Add to this mix transient lags, waste gate or vane controls, intercooler sizing, knock and emissions control systems, and variable valve timing, and the need to perform rapid simulations at multiple levels of detail becomes critically important to success.
Two sets of sample problems are available to demonstrate such simulation capabilities:
