CFD Simulation

Computational Fluid Dynamics (CFD)

Computational Fluid Dynamics (CFD) is a division of fluid mechanics used to solve problems involving fluid flows. These studies use conservation laws that govern fluid motion to accurately predict the way fluid will flow through a process. With origins dating back to the early 1920’s, CFD is now a staple part of many modern-day engineering projects. Our studies often preface the physical manufacture of fluid handling technologies.

 

We use a mixture of powerful computer models and real-world testing data as a framework for our Computational Fluid Dynamics studies. Our Research & Development team test flow requirements for our client’s projects, working to prove concepts before the physical commissioning of a project.

 

Our Process

CFD modelling is used as a starting point for many of our projects. Process conditions such as pressures, flows and physical boundaries are input into our computer models to determine a baseline of system performance. In many cases this then progresses to a physical test of performance in our multi-million-pound Ejector Centre of Excellence.

 

Our practical testing is used to validate the initial figures and drive the project forward. When real-world or scale testing is not viable (perhaps due to project scale, or hazardous liquids involved), CFD can offer a baseline of feasible performance figures.

 

Continuous Development

We not only run Computation Fluid Dynamics projects for client-specific requirements, we also run year-round testing and research projects for the continued development of our core products. We are continuously refining units in our Liquid Jet Compressors, Tank Mixing and Jet Mixing range, maximizing efficiency and improving performance.

 

Tank Mixing

Our modelling is perfectly suited to studies concerning Tank Mixing Solutions. Transvac engineers can offer a detailed CFD analysis to optimise the arrangement of mixers in tanks to avoid bypassing the fluid or creating dead-spots. Transvac’s in-house research team can assess the quality of mixing based on various installation options, including manifold layouts, mixer inlet elevations and angles. This is particularly beneficial for larger tanks where dead-spots can be difficult to predict.

 

Transvac recently worked with two very different clients to offer CFD analysis alongside their tank jet mixer projects. The first project was to determine the required spool angles for 8 mixers turning over waste water containing solids. The second project utilised our study to determine the best design for multiple mixers across 6 diesel tanks, each containing 2 identical Tank Jet Mixers.

 

Erosion & Cavitation Modelling

For Slurry and Sand Pumping applications, we have performed countless tests to improve the abrasion resistance of our ejectors. Our abrasion resistant Ejectors are fitted with high wear components and are highly resistant to particle impingement and cavitation. Learn more on our Sand Pumping page.

 

University Research

Although the majority of our work is self-funded. We have worked as the senior research partner on several occasions with the University of Nottingham’s faculty of Chemical & Environmental Engineering. These studies have offered a handful of University research students to experience real-world CFD modelling projects.
