The New Chapter of Transonic Compressor Cascade Design at the DLR [PDF]
Journal of Turbomachinery, 2022 AbstractThe design of compressor blades has been transformed by the advent of optimization algorithms, allowing designers to focus on finding the best optimization strategy for a desired application. However, transonic flow conditions on compressor blades still present considerable modeling challenges, even for a 2D blade section.

Performance Experiment of R290/CO2 Cascade Refrigeration System
Zhileng xuebao, 2007 Performance experiments of R290/CO2 cascade refrigeration system were conducted. The performance of a cascade refrigeration system having a high temperature cycle using R290 as refrigerant and a CO2 based low temperature cycle was compared with that of a

Inlet Flow Angle Determination of Transonic Compressor Cascades [PDF]
Journal of Turbomachinery, 1991 Tests of transonic compressor cascades require special measuring techniques to determine the inlet flow angle around sonic inlet flow conditions. One of the main requirements for these methods is the ability to adjust the inlet flow angle during the test to a prescribed value.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Effect of Blade Slot Positioning Close to Blade Root on the Performance of Highly Loaded Helium Compressor [PDF]
Journal of Applied Fluid MechanicsThe helium compressor has the inherent characteristics of a lower single-stage pressure ratio and a higher number of stages than an air compressor. The highly loaded design method effectively addressed the compressibility issue of the helium compressor ...

Turbulence Amplification with Incidence at the Leading Edge of a Compressor Cascade [PDF]
International Journal of Rotating Machinery, 1996 Detailed measurements, with a two‐component laser‐Doppler velocimeter and a thermal anemometer were made near the suction surface leading edge of controlled‐diffusion airfoils in cascade. The Reynolds number was near 700,000, Mach number equal to 0.25, and freestream turbulence was at 1.5% ahead of the cascade.It was found that there was a localized ...

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo
FEBS Open Bio, EarlyView.To test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...
