Numerical simulations of sunspots [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractThe origin, structure and evolution of sunspots are investigated using a numerical model. The compressible MHD equations are solved with physical parameter values that approximate the top layer of the solar convection zone. A three dimensional (3D) numerical code is used to solve the set of equations in cylindrical geometry, with the numerical ...

Numerical simulations of bouncing jets [PDF]
International Journal for Numerical Methods in Fluids, 2015 SummaryBouncing jets are fascinating phenomenon occurring under certain conditions when a jet impinges on a free surface. This effect is observed when the fluid is Newtonian and the jet falls in a bath undergoing a solid motion. It occurs also for non‐Newtonian fluids when the jets fall in a vessel at rest containing the same fluid.

In-shock cooling in numerical simulations [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 We model a one-dimensional shock-tube using smoothed particle hydrodynamics and investigate the consequences of having finite shock-width in numerical simulations. We investigate the cooling of gas during passage through the shock for different cooling regimes. For a shock temperature of 10^5K, the maximum temperature of the gas is much reduced and the

Numerical Simulations of Turbulent Combustion
Fluids, 2020 Turbulent burning of gaseous fuels is widely used for energy conversion in stationary power generation, e.g., gas turbines, land transportation, e.g., piston engines, and aviation, e.g., aero‐engine afterburners[...]

Numerical simulations of wave breaking [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2005 This paper is devoted to the numerical simulation of wave breaking. It presents the results of a numerical workshop that was held during the conference LOMA04. The objective is to compare several mathematical models (compressible or incompressible) and associated numerical methods to compute the flow field during a wave breaking over a reef.

Differential Models, Numerical Simulations and Applications
Axioms, 2021 Differential models, numerical methods and computer simulations play a fundamental role in applied sciences. Since most of the differential models inspired by real world applications have no analytical solutions, the development of numerical methods and ...

An approach to consider the arterial residual stresses in modelling of a patient-specific artery
Advances in Mechanical Engineering, 2016 In this work, the residual stress state of a human common carotid artery is predicted using the so-called thermomechanical analogy approach. The purpose of the approach is to enable consistent mapping of residual stresses and the respective configuration

Numerical Simulations of M51 [PDF]
Symposium - International Astronomical Union, 1999 No conference on the interaction of galaxies would be complete without a contribution on M51 (NGC5194) and its companion NGC5195. Much observational and theoretical work has been carried out to try to understand this interacting pair, and to elucidate the morphological features and weak AGN which are thought to be the result of the interaction.
