Multi-Phase Flows CFD Analysis

Multi-Phases flows involve combinations of solids, liquids and gases which interact. Computational Fluid Dynamics (CFD) is used to accurately predict the simultaneous interaction of more than one combination of phases that can be gases, solids or fluids. Typical applications involve sprays, solid particulate transport, boiling, cavitation, state-changes, free surface flows, dispersed multiphase flows, buoyancy problems and mixed species flows. For example, the risks from flow or process-induced vibration excitation of pipework are widely acknowledged in onshore process plants, offshore topsides and subsea facilities. Multiphase flow is particularly of concern because forces can vary considerably with flow regimes, and so relatively small changes in the gas to oil ratio can result in significant changes in dynamic force levels. These forces can be relatively broadband in nature and can therefore excite a range of structural modes.

Enteknograte Engineering provides all forms of multi-phase flow analyses ranging from simple particle tracking calculations for industrial applications through to comprehensive design and optimisation of spray equipment and fluid jets. Enteknograte engineering team quickly evaluate alternative product and process designs to increase efficiency, reliability, safety and durability in a competitive, time-critical environment.

We Use CFD tools such as Ansys Fluent and Siemens Star-ccm+ , OpenFoam and FEA Tools such as Abaqus,  LS-DYNA and MSC Nastran with combination of very experineced engineers to help our customers in:

Multiphase Flows types and application

Our Engineers account the interactions between liquids, solids and gases. Each of these varied multiphase challenges requires a different modeling approach with Euler-Euler such as VOF or Euler-Lagrange method such as using Discrete Element Method to capture immersed particles interaction.

Considering complexity and needs to have new procedure and constitutive equation, we must try to develop new FEA and CFD based software to overcome engineering challenges.

FEA and CFD based Programming needs experience and deep knowledge in both Solid or fluid mechanics and programming language such as Matlab, Fortran, C++ and Python.

Enteknograte’s engineering team use advanced methodology and procedure in programming and correct constitutive equation in solid, fluid and multiphysics environment based on our clients needs.

We use subroutine’s with programming languages such as Fortan, C and Python in CFD and FEA sofware such as Abaqus, Ansys, Fluent and Star-ccm+ to add new capability and Constitutive equation.

Enteknograte use Mathematical Methods and Models for Engineering Simulation. We, focuses on numerical modelling and algorithms development for the solution of challenging problems in several engineering sectors specialized in the development of software for the numerical discretization of partial differential equations, linear algebra, optimization, data analysis, High Performance Computing for several engineering applications.

Together, we enable customers to reduce R&D costs and bring products to market faster, with confidence.
