I. Introduction
The objective of the Stanford ASC project2
is to develop a framework able to perform multi-disciplinary,
integrated simulations on massively parallel platforms.3, 4
This paper focuses on the turbomachinery compu-
tation and, in particular, on the physics of interaction of different turbomachinery components in the engine.
Typical flow features such as tip and horse-shoe vortices as well as blade wakes will be discussed for these
multi-component turbomachinery simulations.
The compressor and turbine of a modern turbofan engine, Figure 1, typically have two counter-rotating
concentric shafts to allow for different rotational speeds of their components as well as a reduction of net
torque. The low-pressure parts rotate at a lower rate than the high-pressure components. Typical rotation
rates are 5,000 to 7,000 RPM for the former and 15,000 to 20,000 RPM for the latter. The compressor and
turbine themselves consist of a series of rotors and stators for which the blade counts are normally chosen
