STI specializes in the analysis, design, and manufacture of advanced fluid mechanical systems for a wide variety of applications. Fluid analysis and design is critical for our gas discharge and chemical laser technology.
A repetitively pulsed gas discharge laser creates hot gas with each discharge that must be cooled and reconditioned before the next shot. As the repetition rate increases, this task becomes more difficult. STI has led the way in the design of the flow loops necessary to circulate the gases in these lasers. Using state-of-the-art codes and our extensive experience, we design and fabricate all the flow loops for our custom-made discharge lasers (see Custom Lasers).
We have a patented technique for generating very uniform droplets. The uniform surface areas of these droplets relative to their volume permits optimizing chemical reactions that occur at the surfaces. For example, these uniform droplets can improve the performance of chemical oxygen iodine lasers (COIL) by efficiently generating the excited-state oxygen atoms needed in these devices. (See STI's support of the ALTB program.) Other potential uses for uniform droplets include advanced sprayers and heat exchangers.
Our fluid engineering capabilities are also available as a separate service to customers (see Engineering Services). This includes related technologies such as analysis and design of heat exchangers. Below summarizes our capabilities.
- Mass and heat transfers with chemical reaction kinetics
- Unsteady compressible flow
- Two-phase flows
- Shock wave propagation
- Computational analysis (FLUENT)
