The theoretical approaches to the erosion and wetting/flowing phenomena during the laser brazing process were made by the computer simulation.
The preheating temperature profile measured in the tandem beam brazing was counted in the simulation (Fig.6(b)).
It follows that the wetting/flowing behaviors of the filler metal during the laser brazing process can be predicted by the computer simulation.
(3) The flow of the melted Au-18%Ni filler metal on a butt joint of Inconel 600 during the laser brazing process was analyzed by the computer simulation.

Optimal simulation for large dynamic systems Robert E.
When a model is selected for simulation, it is tempted to believe that the higher the model order, the more accurate the simulation result.
This myth has driven the efforts to use computation-intensive tools, such as computational fluid dynamics (CFD) and finite element analysis (FEA), in system modeling, which usually generate simulation models of tens of thousands or even millions of order.
Therefore, both the dimension and the realization of the simulation model can influence the performance of a computational simulation.
A fixed point digital simulation problem is considered.

Mathematical models Along with the rapid expanding of CFD commercial software, numerical simulation speeds up for more vivid comprehension of the mechanism.
Calculation subprograms of numerical simulations on the density, film thickness, isobaric specific heat capacity and viscosity are conducted.
The simulation results predict that the average concentration of once film-inverse scheme is slightly lower than that of the once mixing uniform scheme.

Numerical simulation of heat and mass transfer enhancement in absorption process with double-side film-inversion.

The computer simulation of the casting detects the risering problems and provides remedies without having actually produced the casting.
The method could be used as guidelines/riserng rules in metal casting since the computer simulation does not provide the initial riser design and does not automatically optimize the risering.
It is also useful in developing a reasonable starting point for computer simulation of casting process, which shortens the iteration optimization cycle.
