RISEffect of Blade Thickness on Hemodynamics and Hemolysis: A Case Study of Pediatric Centrifugal Blood Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Blood pumps, critical components in ventricular assist devices and extracorporeal membrane oxygenation systems, are primarily evaluated based on their ability to minimize blood damage through optimized design. Despite ...
Cavitation Performance of a Pump With Independently Rotating Inducer and Impeller in Co-Rotation and Counter-Rotation Modes by Varying Rotor Speeds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Centrifugal pumps, consisting of an inducer and impeller, are used in various industries such as marine, aerospace, and nuclear. Typically, inducers and impellers in centrifugal pumps are fixed on the same shaft, having ...
Experimental Study of a Novel Centrifugal Compressor With Two Successive and Independent Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study deals with a low pressure-ratio centrifugal compressor consisting of two counter-rotating rotors called a counter-rotating centrifugal compressor (CRCC). The design method based on the loss model was presented ...
Study of the Hydraulic Performances of Two Inducers in Water—CO2 Mixture—Toward Performance Improvement With Suppression of Prerotation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The inducers increase the pressure available at the inlet of the impellers of centrifugal pumps. This technological solution may induce instabilities, such as prerotating flow at partial flow rates. The scientific literature ...
Study of the Cavitating Instability on a Grooved Venturi Profile
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Instabilities of a partial cavity developed on a hydrofoil, a convergingdiverging step, or in an interblade channel have already been investigated in many previous works. The aim of this study is to evaluate a passive ...
Experimental Study of the Hydraulic Performances of Two Three-Bladed Inducers in Water, Water With Dissolved CO2, and Jet Fuel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inducers in centrifugal pumps are generally placed upstream to increase the pressure before the impeller and prevent cavitation occurrence. Their general goal is to obtain a positive impact on the performances of a pump ...
