Both scSTREAM and SC/Tetra are general-purpose thermo-fluid analysis CFD software packages that can be used to simulate chemical reactions along with the thermal and fluid analysis. Production of new chemical species and/or heat can be considered using the chemical reaction function.
Chemical Vapor Deposition
CFD is used for Chemical Vapor Deposition (CVD) process analysis that is used to generate thin films such as silicon on printed circuit boards. SC/Tetra can handle a multiple-gas mixing analysis as well as a single carrier gas.
CFD analysis is also used for the analysis of the dye coating process. This process uniformly coats materials with a dye liquid (paint) using wall movement. The free surface condition is used at the liquid/air interface since the thickness of liquid is the parameter being calculated. CFD enables conducting parametric analyses to evaluate the effects of changing the velocity of the moving wall, wall roughness, viscosity and velocity of the liquid.
For a mixing tank that mixes multiple materials, SC/Tetra is used to evaluate the performance of the mixing blades and mixing tank pattern. scSTREAM can be used to evaluate mixing multiple materials.
These tools can be applied to simulate a wider variety of chemical phenomena by using additional functions such as chemical reaction, particle tracking, and multi-phase flow along with the simple thermal/fluid analysis.
