TLDR
A fluid is a substance in which the constituent molecules are free to move relative to each other, and in a solid, the relative positions of molecules remain essentially fixed under non-destructive conditions of temperature and pressure.Abstract:
A fluid is a substance in which the constituent molecules are free to move relative to each other Conversely, in a solid, the relative positions of molecules remain essentially fixed under non-destructive conditions of temperature and pressure While these definitions classify matter into fluids and solids, the fluids subdivide further into liquid and gasesread more

Design methodology for biomimetic propulsion of miniature swimming robots
Bahareh Behkam,Metin Sitti +1 more
TL;DR: In this paper, two new methods of propulsion inspired by the motility mechanism of prokaryotic and eukaryotic microorganisms are proposed, and the optimized design parameters for each of the two propulsion modes are demonstrated.

Microinfusion Using Hollow Microneedles
Wijaya Martanto,Jason S. Moore,Osama Kashlan,Rachna Kamath,Ping M. Wang,Jessica M. O'Neal,Mark R. Prausnitz +6 more
TL;DR: By partially retracting microneedles after insertion and other methods to overcome flow resistance of dense dermal tissue, protocols can be designed for hollow microneEDles to microinfuse fluid at therapeutically relevant rates.
Journal ArticleDOI
Radiation-driven winds from luminous accretion discs
TL;DR: In this article, the authors study the hydrodynamics of radiation-driven winds from luminous accretion disks in which the radiation force is mediated primarily by spectral lines and find that the outflow is intrinsically unsteady and characterised by large amplitude velocity and density fluctuations.
Journal ArticleDOI
Co-Simulation: A Survey
TL;DR: The need for finding generic approaches for modular, stable, and accurate coupling of simulation units, as well as expressing the adaptations required to ensure that the coupling is correct, is identified.
Journal ArticleDOI
Numerical Simulations of Mass Outflows Driven from Accretion Disks by Radiation and Magnetic Forces
TL;DR: In this article, the authors studied the two-dimensional, time-dependent magnetohydrodynamics of radiation-driven winds from luminous accretion disks initially threaded by a purely axial magnetic field.

Mechanics of Fluids
TL;DR: In this article, the authors present fundamental concepts and principles governing fluids in motion problems, including the Momentum Equation (ME) and the Laminar Flow between Solid Boundaries (LFL) problems.

Experiments with Fluid Friction in Roughened Pipes
C. F. Colebrook,C. M. White +1 more
TL;DR: Nikuradse as discussed by the authors showed that the resistance law of the Karman-Prandtl theory for smooth surfaces was satisfactorily satisfied with respect to the size of roughness grains.
