A Mathematical Model of Gas-Turbine Pump Complex

Mathematical Techniques behind the Gas Turbine

A ir travel is now common and significant advances have beenmade in the way aircraft are designed and operated since their first introduction. They are now much quieter and more efficient than their earlier counterparts and perform this feat whilst carrying greater payloads. The use of modern materials and manufacturing techniques play a significant part in this achievement; as do the methods o...

Diagnosis of fuel pump measurement bias in gas turbine engines

Hysteresis Characteristic in Hump Region of a Pump-Turbine Model

The hump characteristic is one of the major instabilities in pump-turbines. When pumpturbines operate in the hump region, strong noise and serious fluctuations could be observed, which are harmful to the safe and stable operations and even destroy the whole unit as well as water conveyance system. In this paper, a low specific speed (nq = 36.1 min−1) pump-turbine model was experimentally invest...

Constrained Model Predictive Control of Low-power Industrial Gas Turbine

Nowadays, extensive research has been conducted for gas turbine engines control due to growing importance of gas turbine engines for different industries and the need to design a suitable control system for a gas turbine as the heart of the industry. In order to design gas turbine control system, various control variables can be used, but in the meantime, fuel flow inserting into combustion cha...
