Jet Engine Research

In recent years a lot of attention has been devoted to the study of air flow through turbomachines.  The main reason for this interest is that when a turbomachine, such as a jet engine, operates close to its optimal operating parameter values, the flow can become unstable.  These instabilities put a large stress on the engine and in some cases the engine needs to be turned off in order to recover original operation.  For this reason jet engines are currently operated away from their optimal operating parameter values increasing both fuel consumption and the engine weight.


The continuing evolution of the surface of the earth poses a challenging and fascinating modeling problem. The earth’s surface is composed of many substances: soil, sand, vegetation, different types of rocks. Its face is further complicated by topography which continues to change over time due to tectonic uplift and earthquakes. Due to the complexity of most landsurfaces and the instability of some it has taken many years to develop models.
