“…Besides that, some studies on the discharge coefficient of the receiver hole which represents the losses occurring in the receiver hole were conducted by the researchers [5][6][7][8], and the results showed that a peak in discharge coefficient of receiver holes occurs at a minimum of the tangential velocity differential. Generally, besides cooling blades, the cooling air in the preswirl rotor-stator system plays roles to pressurize the cavity and cool the rotor wall of cavity.…”

“…5,6 Luo et al 7 numerically simulated the flow and heat transfer characteristics of a direct pre-swirl system using the realizable κ-ε turbulence model, verified with the experimental results. Then, Popp et al 8 numerically investigated the flow characteristics of the receiver hole and proposed that the relative parameters should be used to describe the aerodynamic characteristics of the rotating receiver hole.…”

The pre-swirl system can transfer the cooling air from the compressor to the turbine rotor blades with a lower relative total temperature to avoid extreme thermal shock. This work proposes a novel test rig to investigate the flow and aero-thermal characteristics in a cover-plate type pre-swirl system. The performed experimental and numerical studies focus on the effects of the partial pre-swirl nozzle closing modes on the mass flow rate of air supply, temperature, and uniformities in a pre-swirl system by application of the pre-swirl noz-

Performance analysis and testing of the Mini Gas Turbine was carried out in Wentworth Institute of Technology's Thermodynamics Laboratory. The computational tool allows students to focus on more design-oriented problems. Furthermore, students had the ability to see immediate results to variations of the design conditions as well as different parameters that would affect the mini turbine. This project was carried out as a senior design project (Capstone), the students updated the existing data acquisition system, writing a new data acquisition program in LabVIEW, installing new pressure and temperature sensors, and performing a first and second law of thermodynamics analysis on the engine in Engineering Equation Solver. In order to update the existing data acquisition system, new NI SCB-68 connector blocks were implemented along with NI USB-6251 terminals. The new hardware is operated through a LabVIEW program running on a new laptop designated and mounted to the mini jet turbine housing. Instrumentation, testing, and calibration are the three main milestones for this project As a result, The Inlet Mass Flow Rate numeric indicator value is calculated, not measured. The calculated value is dependent on the measured values of Compressor Inlet Temperature (T1), Compressor Inlet Static Pressure (Ps), and Compressor Inlet Dynamic Pressure (Pt-Ps). However, the pressure, temperature and thrust were tested as a function of RPM. The mini turbine engine is ready to be used in student experimental settings. Feedback from students proves that the use of different tools significantly enhances the student learning experience and encourages the students to use different theory from different courses, make the course more dynamic, and motivate the students to learn the material.
