Eigenfrequency sensitivity analysis of flexible rotors [PDF]

open access: yesApplied and Computational Mechanics, 2007
This paper deals with sensitivity analysis of eigenfrequencies from the viewpoint of design parameters. The sensitivity analysis is applied to a rotor which consists of a shaft and a disk. The design parameters of sensitivity analysis are the disk radius

Numerical simulation of turbulent flow between shrouded contra-rotating disks

open access: yesAdvances in Mechanical Engineering, 2016
The turbulent flow between shrouded contra-rotating disks was numerically studied with a two-layer turbulence model and a modified Launder–Sharma low-Reynolds number k - ε model.

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

open access: yesAdvanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Hydrothermal analysis of MHD nanofluid (TiO2-GO) flow between two radiative stretchable rotating disks using AGM

open access: yesCase Studies in Thermal Engineering, 2019
Nanofluid flow between two stretchable and rotating disks with homogeneous and heterogeneous reactions and Joule heating is investigated in existence of magnetic field. Thermal radiation effect has been considered in energy equation.

Interfacial Acid Sites‐Mediated ZnO‐Based Electrocatalysts for Sustainable Dual‐Pathway H2O2 Production and Rechargeable Zn‐H2O2 Electrochemical Cell

open access: yesAdvanced Materials, EarlyView.
In this work, a synergistic strategy introduces interfacial acid sites, oxygen vacancies, and built‐in electric field into ZnSe/ZnO heterojunction to optimize its electronic structure and electrode micro‐environment. This overcomes sluggish oxygen reduction reaction kinetics and low H2O2 selectivity, achieving record H2O2 productivity (754.4 M gcat−1 ...

Strength of Rotating Disks

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1952
The criterion for rupture of brittle materials like cast iron is σ=σB, where, σ is mean value of normal tensile stress on the surface of rupture ; the mean is generally a weighted mean, the effectiveness to the load being taken into account, and σB is ultimate tensile strength.

Basic Generic Properties of Regular Rotating Black Holes and Solitons

open access: yesAdvances in Mathematical Physics, 2017
We present a systematic description of the basic generic properties of regular rotating black holes and solitons (compact nonsingular nondissipative objects without horizons related by self-interaction and replacing naked singularities). Rotating objects
