Models in physics [PDF]

open access: yes, 2018
In its most common use, the term ‘model’ refers to a simplified and stylised version of the so-called target system, the part or aspect of the world that we are interested in. For instance, in order to determine the orbit of a planet moving around the sun we model the planet and the sun as perfect homogenous spheres that gravitationally interact with ...

Full-scale physical modelling of fissure grouting in deep underground rocks

open access: yesTunnelling and Underground Space Technology, 2019
Parameters predetermination and grouting quality evaluation are of vitally importance issues for rock grouting. Because of emerged new features (e.g.

Physical Modelling of High Stiffness Large Diameter Steel Tubular Pile Subjected to One-Way Horizontal Cyclic Loading

open access: yesGeotechnics, 2023
Two centrifuge model tests were conducted, each with three large diameter steel tubular piles installed under similar conditions, i.e., diameter (Φ) = 2 m; thickness (t) = 25 mm; loading height from the rock surface (HL) = 6.5 m, but different rock ...

Physical Modelling of the Set of Performance Curves for Radial Centrifugal Pumps to Determine the Flow Rate

open access: yesApplied System Innovation, 2023
To depict the pump power characteristics of radial centrifugal pumps, a physical model was developed. The model relies on established empirical equations.

Physical modelling of the response of reef islands to sea-level rise

open access: yesGeology, 2019
Sea-level rise and increased storminess are expected to destabilize low-lying reef islands formed on coral reef platforms, and increased flooding is expected to render them uninhabitable within the coming decades.

Beyond equilibrium: Re-evaluating physical modelling of fluvial systems to represent climate changes

open access: yesEarth-Science Reviews, 2018
The interactions between water, sediment and biology in fluvial systems are complex and driven by multiple forcing mechanisms across a range of spatial and temporal scales.

Physical Modelling in MvStudium

open access: yesSNE Simulation Notes Europe, 2012
In this paper, we describe “physical” modeling technology in MvStudium that is a graphical environment for modeling and simulation of complex dynamic systems. MvStudium.6 modeling language (MVL) is based on open hybrid automata or Behavior-Charts (for short BCharts), functional diagrams, and supports object-oriented modeling. B-Chart is an extension of

Physical modelling in biomechanics [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
Physical models, like mathematical models, are useful tools in biomechanical research. Physical models enable investigators to explore parameter space in a way that is not possible using a comparative approach with living organisms: parameters can be varied one at a time to measure the performance consequences of each, while values and combinations not

Scale effects in physical modelling of a generalized OWC

open access: yesOcean Engineering, 2018
Physical modelling is extensively applied in the study of Oscillating Water Column (OWC) devices since it furnishes a reliable evaluation of nonlinear effects, as those induced by the interaction between surface waves and air inside the pneumatic chamber.
