Transvac’s has the capability to carry out computational fluid dynamics (CFD) simulations on a range of different fluid-flow and industrial problems related to Ejector technologies. Transvac can offer customers CFD studies to demonstrate the performance of Ejector technology for their specific applications.
CFD modelling is the starting point for many of Transvac’s development projects. The use of computational modelling can reduce development time and reduce costs when a project reaches the prototyping phase of development.
Process conditions such as pressures; flows; material properties; and physical boundaries, taken from the real-world or design conditions, are inputted to determine a baseline of system performance. This information then forms the basis of physical test of performance in Transvac’s Ejector test facility.
Physical testing data is used to validate the initial CFD figures and drive the project forward. This data can either be provided by experimental testing in Transvac’s R&D facility or by data found in literature.
What is CFD and what can it do?
Computational Fluid Dynamics (CFD) is a division of fluid mechanics used to solve problems involving fluid flows using computer simulation to solve the Reynolds Averaged Navier-Stokes (RANS) fluid flow equations. It allows the engineers to ‘see into the flow’ within ejectors; pipes; and mixing tanks and probe the physical conditions calculated by the selected CFD models.
CFD is a mature simulation technology and is now a part of many modern engineering projects. Transvac’s studies often preface the physical manufacture of their novel fluid handling technologies.
Transvac’s core CFD competencies are:
- Incompressible liquid-liquid Ejector simulations
- Compressible gas-gas, steam-gas Ejector simulations
- Multiphase ejector modelling using their own unique validated code. This is used for modelling their liquid jet compressor (LJC) ejector technologies.
- Multiphase modelling for vessel mixing, settling and solids dispersion.
- Coupled erosion and cavitation modelling of Ejectors; pipes; and pipe like structures from solid particle laden fluid flows
- Condensating and evaporating flows within Ejectors.
- Flow generated acoustic simulations including vibration analysis
Transvac’s CFD team has extensive experience in other areas of fluid flow modelling.
When real-world or scale testing is not viable a CFD study can provide a baseline of feasible performance figures. For example, Gas-Gas Ejectors and Tank Jet Mixing applications where the equipment scale and availability of fluids is an issue. A CFD study can also be used to for a FAT (Factory Acceptance Test) where it physically impossible to physically test the supplied Ejector.
