Influence of Impeller Gap Drainage Width on the Performance of Low Specific Speed Centrifugal Pump

Journal of Marine Science and Engineering, 2021
The centrifugal pump is one of the most important pieces of energy-consuming equipment in various hydraulic engineering applications. This paper takes a low specific speed centrifugal pump as the research object.

Flows of gas through a protoplanetary gap [PDF]

Nature, 2013
The formation of gaseous giant planets is thought to occur in the first few million years after stellar birth. Models predict that the process produces a deep gap in the dust component (shallower in the gas). Infrared observations of the disk around the young star HD 142527 (at a distance of about 140 parsecs from Earth) found an inner disk about 10 ...

Flux Flow Resistivity in Two-Gap Superconductor [PDF]

Journal of the Physical Society of Japan, 2005
Summary: We investigate the flux flow state in a two-gap superconductor in which two \(s\)-wave gaps with different amplitudes exist on two separate Fermi surfaces. The flux flow resistivity is obtained on the basis of the Bardeen-Stephen relation and the result agrees well with the anomalous field dependence of the flow resistivity recently observed ...

Research on Taylor Vortex and Heat Transfer in AxialRadial Cooling Motor

Journal of Harbin University of Science and Technology, 2019
The analysis of flow and transfer of heat in the air gap of synchronous motor associated with axial-radial ventilation system is important due to the complexity of flow of cooling air in the air gap between rotor and stator.

Comparative Study on the Fractal and Fractal Dimension of the Vortex Structure of Hydrofoil’s Tip Leakage Flow

Fractal and Fractional, 2023
Axial-flow turbomachinery is widely used in low head water transfer and electricity generation projects. As there is a gap between the impeller and casing of the tubular flow unit, the fluid will cross the gap to form tip leakage flow, which may induce ...

Analytical Calculation of Annular Gap Throttling of Damping Valve [PDF]

MATEC Web of Conferences, 2020
For the throttling characteristics of the suspension system damping valve, an analytical method for gap throttling based on turbulent flow state was proposed for the first time. The boundary layer theory was used to give the expression of the three-layer

Unstable simultaneous whirl of two cylinders in a concentric double rotating cylinder system

Mechanical Engineering Journal
This study investigated the unstable simultaneous whirl of two cylinders in a concentric double rotating cylinder system, with both co- and counter-rotation. The axes of both cylinders were radially elastically supported independently of each other.

Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.

The HIT Network for Children and Adolescents With CNS Tumors Facilitates Improvements of Diagnostic Assessments, Multimodal Treatments, Individual Counseling, and Research in Germany, Austria, and Switzerland

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The HIT network was established in 2000 to create a population‐based structure aiming to improve survival rates and reduce late effects for children with central nervous system (CNS) tumors by conducting comprehensive clinical trials.
