The tip leakage flow not only is responsible for a significant amount of aerodynamic losses in a turbine stage, but also leads to high heat-loads on the tip region. The paper presents a numerical investigation of influences of tip injection on aero-thermal performance of the tip leakage flow for...

The flow in turbomachinery is inherently unsteady, and the understanding of the flow interaction in the casing endwall region of shrouded turbine stages is a key requirement in achieving further improvements in performances. Thus, comparative numerical investigations of casing endwall flow...

Life-cycle fossil primary energy consumption (FPEC) and greenhouse gas (GHG) emission intensity of nine types of dominant secondary energy (SE) pathways for China in 2010 are calculated with iterative methods, using the TLCAM (Tsinghua Life-cycle Analysis Model). Three major types of GHG (CO2,...

In this work, an experimental system based on digital real-time holographic interferometry for measuring the mass diffusion coefficients of fluid is introduced. The method of processing interference fringe hologram is also introduced thoroughly. By uncertainties analysis and experimental...
