    The models were constructed by using three measured time-series data sets from General Electric PG 9351FA. J.H.Kim constructed a simulation model of the start-up procedure of heavy duty gas turbines based on the unsteady one-dimensional conservation equations. The dynamic behavior of a 150 MW class gas turbine (GE 7F) was simulated for a full start-up procedure from zero to full speed.

    Erosive wear can be defined as degradation of material due to impact of particles travelling with significant velocity. A tribosystem suffering from erosive wear can be characterized as an open system. In such a system the counter body is continuously replaced. Another feature is that the wear of the counter body is unimportant.

    The two-dimensional multicellular flow is unstable above a Grashof number of about 8550 (with the critical Grashof number for the base flow being 8037). Therefore the flow of air in a sufficiently tall vertical enclosure should be considered to be three-dimensional for most practical applications.
