A three dimensional computational fluid dynamic is used to analyze the mechanisms of flow inside a vortex tube. The K- ω SST turbulence model was applied to predict the performance and turbulent flow behavior inside the tube. The ...

Pyrotechnic Pistons are communally used as fast reacting actuators in many elds and applications, such as seat belt pretensioners, wire and cable cutters and power disconnect devices. The design of such devices is subjected to many ...

A numerical investigation of Turbulent flows through a circular 180° curved bend with defined as the bend mean radius to pipe diameter for a Reynolds number of 4.45×104 is presented in this study . The computation domain is performed ...

Numerical simulations used to predict events are always challenging. Among the challenges is establishing some basis for confidence in the results when no experimental results exist, i.e. a prediction. While there is no assurance that ...

The crashworthiness of marine structures is one of the main area of interest of several parties active in maritime area. The ability of structural material to absorb mechanical energy without fracture, is a very important safety ...

A growing interest in modelling and simulation of machining processes has been witnessed in the past few decades. Smoothed particles hydrodynamics (SPH), one of the latest and developing methods used for that purpose, is a powerful ...

For high frequency analysis, Statistical energy analysis (SEA) has proved to be a promising approach to the calculation of sound transmission in complex structures. In automotive industry and also in civil engineering, most of noise ...

In recent years industries like aerospace, automotive and those related to oil production have increased their trustfulness on numerical models and codes for the design, research, production and verification of highly critical parts ...

Hot stamping is one way to produce automotive steel parts of a complex shape with very high mechanical characteristics. In this process heat plays an essential role. To reduced investment costs and for more production flexibility ...

An electromagnetism module has being developed in LS-DYNA for coupled mechanical/thermal/electromagnetic simulations. More recently, a new 2D axi-symmetric version of this solver was introduced, allowing much faster simulations. In ...
