  2. CFD-DEM model - Wikipedia

    en.wikipedia.org/wiki/CFD-DEM_model

    A CFD-DEM model is suitable for the modeling or simulation of fluid-solids or fluid-particles systems. In a typical CFD-DEM model, the phase motion of discrete solids or particles is obtained by the Discrete Element Method (DEM) which applies Newton's laws of motion to every particle [1] and the flow of continuum fluid is described by the local averaged Navier–Stokes equations that can be ...

  3. Dynamical simulation - Wikipedia

    en.wikipedia.org/wiki/Dynamical_simulation

    Animation based on piston motion equations; the crank is driving the piston, with variations in the speed of rotation, the crank radius, and the rod length.. Dynamical simulation, in computational physics, is the simulation of systems of objects that are free to move, usually in three dimensions according to Newton's laws of classical dynamics, or approximations thereof.

  4. Computational fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Computational_fluid_dynamics

    A computer simulation of high velocity air flow around the Space Shuttle during re-entry A simulation of the Hyper-X scramjet vehicle in operation at Mach-7. The fundamental basis of almost all CFD problems is the Navier–Stokes equations, which define many single-phase (gas or liquid, but not both) fluid flows.

  5. Newton's laws of motion - Wikipedia

    en.wikipedia.org/wiki/Newton's_laws_of_motion

    Newton's third law must be modified in special relativity. The third law refers to the forces between two bodies at the same moment in time, and a key feature of special relativity is that simultaneity is relative. Events that happen at the same time relative to one observer can happen at different times relative to another.

  6. Lorentz force velocimetry - Wikipedia

    en.wikipedia.org/wiki/Lorentz_force_velocimetry

    The interaction between eddy currents and total magnetic field gives rise to Lorentz force that breaks the flow. By virtue of Newton's third law "actio=reactio" a force with the same magnitude but opposite direction acts upon its source - permanent magnet. Direct measurement of the magnet's reaction force allows to determine fluid's velocity ...

  7. List of computer simulation software - Wikipedia

    en.wikipedia.org/wiki/List_of_computer...

    ProLB - a computational fluid dynamics simulation software based on the Lattice Boltzmann method. PTV Vissim - a microscopic and mesoscopic traffic flow simulation software. PSF Lab - calculates the point spread function of an optical microscope under various imaging conditions based on a rigorous vectorial model.

  8. List of chemical process simulators - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_process...

    This is a list of software used to simulate the material and energy balances of chemical process plants. Applications for this include design studies, engineering studies, design audits, debottlenecking studies, control system check-out, process simulation, dynamic simulation, operator training simulators, pipeline management systems, production management systems, digital twins.

  9. Bernoulli's principle - Wikipedia

    en.wikipedia.org/wiki/Bernoulli's_principle

    Bernoulli's principle can be used to calculate the lift force on an airfoil, if the behaviour of the fluid flow in the vicinity of the foil is known. For example, if the air flowing past the top surface of an aircraft wing is moving faster than the air flowing past the bottom surface, then Bernoulli's principle implies that the pressure on the ...
