Effect of the Diameter of Pressure-Balance Pipe on Axial Hydraulic Thrust [PDF]
Journal of Marine Science and Engineering, 2021 The axial hydraulic thrust has great influence on the safety and stability of a pump turbine. A common way to balance hydraulic thrust is to install a pressure-balance pipe, and the change in pipe diameter is one of the important factors affecting axial ...

Behaviour of Small Diameter Steel Tubes Under Axial Compression
Structures, 2017 Abstract Small diameter steel tubes are used in many civil engineering applications. Recently, the behaviour of concrete columns reinforced with small diameter steel tubes was experimentally and analytically investigated. This study explores the effect of unsupported length to the outside diameter ( L / D ) ratio on the axial compressive behaviour of ...

The Study of Axial Heat Conduction with Various Hydraulic Diameters of Microchannel
Procedia Engineering, 2014 AbstractThis study presents the discussion of axial heat conduction in different hydraulic diameters of rectangular polydimethylsiloxane (PDMS) microchannels at a Reynolds number of 15. The hydraulic diameters of selected microchannel devices vary from 40 to 196μm with an aspect ratio (i.e. height/width) of 0.1.

New Estimates of Numerical Values Related to a Simplex
Моделирование и анализ информационных систем, 2017 Let \(n\in {\mathbb N}\) and \(Q_n=[0,1]^n\). For a nondegenerate simplex \(S\subset {\mathbb R}^n\), by \(\sigma S\) we denote the homothetic copy of~\(S\) with center of homothety in the center of gravity of \(S\) and ratio of~homothety \(\sigma\). By

Properties of Axial Diameters of a Simplex [PDF]
Discrete & Computational Geometry, 2011 Let S be a nondegenerate simplex in ℝn . It is proved that the minimal possible σ>0, such that a homothetic copy of S of ratio σ contains [0,1]n , is equal to $\sum_{i=1}^{n} 1/d_{i}(S)$. Here d i (S) denotes the length of a longest segment in S parallel to the ith coordinate axis.

Influence of Diameter Increase Speed on Diameter-Axial Rolling of Large 40Cr13 Stainless Steel Ring
Journal of Physics: Conference Series, 2023 Abstract Rolling speed ratios during the rolling process are critical to ring forming in this pepper. The selected roll feed mode is constant with the increasing speed of ring diameter during the main rolling stage. Based on Deform-3D finite element software, a large size ring with a diameter of φ1530 mm was taken as the research object.

Influence of Balance Hole Diameter on Leakage Flow of the Balance Chamber in a Centrifugal Pump
Shock and Vibration, 2021 The balancing holes in centrifugal pumps with seals mounted in both suction and discharge sides are one of the approaches used by pump manufacturers to reduce the axial thrust. The balance hole diameter directly affects the axial force of the centrifugal
