Abstract: In ultrasonic cavitation, iridescent rings always occur around erosion pits on steel surface. These colorful halos can reflect the experienced temperature of the steel surface, but the reason for their formation is ...

Abstract: The performance and stable operating range of compressors are critical for the efficient operation of various turbomachinery systems. To reveal the flow instability mechanism of a high-speed and high-loaded compressor, a ...

Abstract: Pipe diffusers with several different geometries were designed for a highly loaded centrifugal compressor originally using a wedge diffuser. Parametric studies on the effect of pipe diffuser performance of a highly loaded ...

Abstract: Abstract. The supersonic through-flow variable-pitch tandem cascade has a significant potential for widening the acceptable inflow range of fans, but its internal flow mechanisms are not yet fully understood. This study ...

Abstract: Abstract. The loss generation in the corner region of compressors is highly dependent on vortex dynamics. When the Reynolds number (Re) decreases to a critical value, the flow unsteadiness induced by multiscale vortex ...

Abstract: In concrete block pavement, individual blocks are laid in a predetermined pattern to create a surface interlocked with joint filler that has some discontinuities rather than continuous paving. The overall structural stability ...

Abstract: Public–Private Partnerships (PPPs) are widely used in infrastructure construction due to their great advantages in the supply of public services. The evolutionary process linking hybrid governance and PPP project performance, ...

Abstract: This paper describes the stall mechanism in an ultrahigh-pressure-ratio centrifugal compressor, composed of a double-splitter impeller, radial diffuser, and axial diffuser. A model comprising all impeller and diffuser blade ...
