Method of discrete singularities in problems of filler vibrations in fuel tanks under overloads and at low gravity

Вісник Харківського національного університету імені В.Н. Каразіна. Серія: Математичне моделювання, інформаційні технології, автоматизовані системи управління, 2019
The paper is about free vibration problems in fuel tanks with different levels of fillers both under overloads and low gravity. The fuel tanks are considered as rigid shells of revolution.

A computational investigation of vibration of stationary and rotating structures submerged in a liquid [PDF]

Applied and Computational Mechanics, 2008
To realize some technological processes components of a number of stationary and rotating machines work submerged in various liquids. Therefore their vibration is significantly influenced by their interaction with the medium in the surrounding space.

Alte und neue Wege in der Rheometrie der Polymer-Schmelzen

CHIMIA, 1984
Polymer melts are nonlinear, pseudoplastic, viscoelastic, rubberlike liquids. Because of this complex rheological behaviour experimental investigations with conventional methods seem to be insufficient.

Controlling turbulent drag across electrolytes using electric fields

, 2017
Reversible in operando control of friction is an unsolved challenge crucial to industrial tribology. Recent studies show that at low sliding velocities, this control can be achieved by applying an electric field across electrolyte lubricants.

Research on Evaporation Characteristics and Safe Storage Duration of Marine Liquid Hydrogen Storage Tanks Under the Coupling Effect of Heat Leakage and Sloshing

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Liquid hydrogen, a zero‐carbon and high–energy‐density fuel, is a promising option for future oceangoing vessels. During maritime transportation, onboard cryogenic tanks are exposed to ambient heat leakage and ship‐induced roll motion, which can trigger sloshing and fundamentally modify the coupled thermo‐fluid processes governing boil‐off and

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

Theory for acoustic propagation in materials which can support stress and which contain gas bubbles, with applications to acoustic effects in marine sediment and tissue

, 2007
Whilst there is a considerable body of work in the literature on the theory of acousticpropagation in marine sediment, the incorporation of gas bubbles into such theories isdone with the inclusion of assumptions which severely limit the applicability of ...

Sheath‐assisted microfluidics for elasto‐inertial manipulation of micro/nanoparticles: From theory to biomedical applications

Droplet, EarlyView.
This review examines sheath‐assisted elasto‐inertial microfluidics, where viscoelastic and inertial forces synergize to manipulate particles. It analyzes the underlying mechanisms, system designs, and biomedical applications, proposing future research to advance high‐precision technologies.
