Measurements of the flow field around a low pressure turbine blade are presented. The purpose of the experimental study is to investigate the detailed transition and separation characteristics on low pressure turbine blades. The present study focuses on the effect of Reynolds number on the formation of separation bubbles on the turbine blade surface. Specific attention is paid to the flow withi...

The turbocharger and turbocharging have been the inherent component of diesel engines, so that critical parameters of such engines, as BSFC (Brake Specific Fuel Consumption) or thermal efficiency, fuel consumption, BMEP (Brake Mean Effective Pressure), the power density output and emission level have been improved extensively. In general, the turbocharger can be considered as the most complex c...

Aircraft noise is a complex topic which is projected to increase with the increasing number of aircraft and size of the engines. Turbine-powered aircraft produce sounds that are considered pollutants at certain decibel levels. Turbofan engines are inherently quieter than turbojet engines for a given level of thrust. The purpose of this research is to determine if current turbofan noise reductio...

Biomass is identified as one of the major renewable energy sources for electrical power generation. Heavy duty gas turbine engines are preferred for clean and efficient power generation. An extensive literature survey reveals that the governor droop setting of the heavy duty gas turbines varies from 2 percentage to 10 percentage. But it needs to be optimized for analyzing the dynamic response o...

Sensor selection optimization can lead to significant improvements in the controllability and observability of a dynamic system. The aim of this research is to investigate optimal or alternate measurement sets for aircraft gas turbine engine health parameter estimation. A brute force search for the best sensor set is too computationally expensive. Therefore, a Monte Carlo approach is used to pe...
