Computational Fluid Dynamics (CFD)
Computational Fluid Dynamics (CFD) is an invaluable tool in our R&D process. It enables us to gain a precise understanding of the flow conditions within a container. By accurately recreating the process configurations, CFD is not limited by size, allowing us to reliably predict the mixing performance of large tanks, including those with special geometries or unique process requirements. The Greatwall R&D team has completed numerous CFD simulations across various processes, ranging from simple single-phase mixing to more complex multi-phase suspensions, dispersions, and more. This capability allows us to optimize and refine the design and operation of mixing equipment for diverse applications.
Load/No-Load Testing
The equipment at Greatwall Mixers’ laboratory is capable of providing both unloaded and loaded testing for customers. The tested equipment is rigorously evaluated according to relevant standards to ensure objective analysis and recommendations. The large underground testing tank can accommodate mixers with a shaft length of up to 4 meters. The unloaded testing platform can operate mixers with a shaft length of up to 14 meters. Through loaded and unloaded testing, we can identify and prevent potential design or manufacturing errors before shipment.
Mixer Design Selection Process and Management Design Software
In the mixer design process, Greatwall Mixers has developed and procured a series of management and design software tools. Notably, the self-developed design software integrates a vast collection of established design calculation formulas and includes nearly 30 years of Greatwall's design experience. This accumulated experience is critical for guiding the design of new mixers, ensuring that every design decision is backed by practical insights and proven success. These software tools play a vital role in streamlining the design process, allowing for efficient selection and optimization of mixers based on client-specific requirements. By leveraging both the theoretical and practical knowledge embedded in the software, Greatwall Mixers can provide highly accurate and effective solutions for a wide range of mixing needs.
