HYDRAULIC DEVELOPMENT OF A CENTRIFUGAL PUMP IMPELLER USING THE AGILE TURBOMACHINERY DESIGN SYSTEM
TASK Quarterly, 2002 The impeller of an existing industrial pump (with both geometry and performance known) was analyzed and redesigned using an integrated, design/analysis, turbomachinery geometry modeling and flow simulation system.

Energy Science & EngineeringThe rotor blades of an axial‐flow turbine are cantilever structures, and there is inevitably a gap between them and the casing. Due to factors such as rotor wear and unit vibration, the eccentricity of the impeller will change during the operation of the

Energy Science &Engineering, EarlyView.Based on entropy theory, this study presents a comparative numerical analysis of the flow energy dissipation (FED) in a VTSP under two distinct operating conditions: pump condition and turbine condition, both characterized by relatively high hydraulic efficiencies of 88.9% and 87.4%, respectively. In pump condition, the highest FED production occurs in

Energy Science &Engineering, EarlyView.To investigate the influence of discharge valve opening on the self‐priming characteristics of a self‐priming pump, numerical calculations are conducted for four different discharge valve openings based on a circulation piping system. The hydraulic performance and the internal flow characteristics during self‐priming process are obtained.

Energy Science &Engineering, EarlyView.ABSTRACT Traditional air conditioners suffer from low energy efficiency and exacerbate grid peak loads. While ice storage offers energy‐saving potential, the systematic regulation of ice packing fraction (IPF) on cooling consumption and its synergy with dynamic carbon emissions remains unexplored.

Exploration, EarlyView.Our work addresses the challenge of treating triple‐negative breast cancer by developing a multifunctional nanoliposome, ictLipo. The goal was to enhance antitumor immunity by combining photothermal therapy and chemotherapy while simultaneously tackling two major roadblocks: immunosuppression from cholesterol in the tumor microenvironment and therapy ...
