Numerical Simulation of Marine Vehicle Immersed in Water
Journal of Marine Science and Application, 2019This article presents a numerical study of the forces induced by hydrodynamic impact, that is, the impact of a part of the bottom of the hull on the water surface. The prediction of these efforts is often based on numerical simulations to determine the shock intensity of a structure on the surface of a weakly compressible fluid (for example, water ...

Numerical Simulation of Pollutant Transport within an Vehicle Cabin
2011The research by computational fluid dynamics(CFD) was conducted on distribution characteristics of pollutant in the vehicle cabin. The layout of supply openings, the chairs and the human body had importantly effect on the concentration fields. The concentration in near window zone was lower the other zones. The CO2 levels in middle zone was higher than

Numerical simulations of hydrodynamic noise of an underwater vehicle
OCEANS 2014 - TAIPEI, 2014Numerical simulations of hydrodynamic noise are made based on the Large Eddy Simulation for both flow-induced noise and noise from the flow-induced vibration of shell and propeller of an underwater vehicle. All hydrodynamic noises are predicted by using Lighthill's acoustic analogy method, and their variation characteristics along the axial and ...

Numerical simulation of vehicle dynamics for virtual reality
SPIE Proceedings, 2001The paper is devoted to snowmobile and car dynamics simulation in real time mode. This task is typical for trainers and computer games, where a model of moving vehicle is handled interactively. The challenge of real time is to recalculate values of a moving model on each frame, that is, at least 30 times per second and take for this not more than 5 ...
