Invention Reference Number
This technology enables faster, more flexible design and optimization of components used in fluidized bed chemical vapor deposition (FBCVD) systems. By integrating computational modeling, additive manufacturing, and particle image velocimetry, researchers can quickly prototype and refine reaction chambers and gas distributors for a variety of coated particle applications. The process dramatically reduces design time and allows for geometries not feasible through traditional fabrication methods, supporting rapid innovation across energy, aerospace, and advanced manufacturing sectors.
Description
The invention combines computational fluid dynamics (CFD) modeling, additive manufacturing, and the use of particle image velocimetry to accelerate the development and optimization of gas distributors and reaction chambers for FBCVD systems. CFD simulations enable researchers to model particle behavior and assess fluidization efficiency under different geometric configurations. These digitally optimized designs are then prototyped and tested using polymer or ceramic 3D printing and particle image velocimetry, allowing for rapid iteration. Once optimal designs are identified at room temperature, they can be fabricated in high-temperature materials using advanced manufacturing techniques such as direct metal laser sintering or binder jet printing. This approach enables precise control over component design, bypassing the geometric limitations of traditional machining, and significantly shortens the development cycle for customized CVD systems.
