Abstract

Abstract:

It is difficult to use the traditional optical measurement technology measure the three-dimensional flow field inside the turbine blade with complex cooling structures. In this paper， the Magnetic Resonance Velocimetry （MRV） technology was employed to investigate the flow behavior inside a turbine blade with multiple cooling structures， particularly the flow in the blade trailing edge. MRV data were then compared with numerical simulations for validation purposes， and the effect of full-height or half-height pin fins on the flow out of trailing edge holes/slots was studied numerically. The results show that MRV is able to capture the internal flow characteristics of the cooled turbine blade， such as the vortices around the pin-fins and the slots. Furthermore， both MRV data and numerical results show that along the spanwise direction， the mass flow rate of the film hole decreases， while that of the slot increases. It is also found that the influence of full-height and half-height pin fins on the flow out of trailing edge holes/slots is mainly in increasing the flow resistance and the driving pressure difference of the outflow， thereby changing the mass flow rate through the holes/slots. The full-height and half-height pin fins increase the overall outflow of the film holes by about 2.8%， while reducing that of the slots by about 2.8%.

Key words: magnetic resonance velocimetry (MRV), internal flow of turbine blade, composite cooling, flow visualization, numerical calculation
