Testing Part & Pipeline Designs with Computational Fluid Dynamics CFD simulations allow for comprehensive testing that covers everything from pressure to temperature, velocity, turbulence, flow profiles, and swirl as well as more complex behaviors such as pipe wall or component erosion due to particles such as sand, or multiphase flow with liquids in gas or water in oil. We use many hours of CFD iterations to analyze fluid flows, verify part design & performance, diagnose meter station flow problems, and predict flow changes from equipment modifications. Watch a 2-minute short about CPA’s dedicated focus on flow measurement accuracy. #pipelineintegrity #oilandgas #engineering

You know what they say about 10,000 hours: it's the road to mastery in really anything you do. And that's the minimum time that our team has spent conducting Computational Fluid Dynamics, which translates directly to an intimate knowledge of what works (and what doesn't) in pipeline flow conditioning. #pipelineintegrity #oilandgas #engineering

Oh man, if you aim to accurately predict the so-called "pressure drop" in turbulent internal flow using CFD, something that might seem trivial at first glance (why not?), you'd better hold on tight; there are twelve terms involved in the power balance! Using Reynolds averaging, we typically derive turbulent and mean kinetic energies by taking moments of the momentum balance with conveniently selected fluctuating velocities. In an attempt to simplify, I applied Reynolds averaging to the dot product of velocity and the momentum conservation equation. This procedure appears to give a conservation law for the total macroscopic power. Interestingly, it does not include the well-known turbulence production term. This makes sense since turbulence production appears with opposite signs in the mean and turbulent kinetic energy equations. This raises a tricky question: does turbulence production really exist?. I think in some sense it does; but considering that the same reasoning can be applied to the dissipations if the internal energy of the open system is included in the balance, we must be careful in the meaning we assign to the word "exist". Continuum mechanics raises existential questions about phenomena that are not truly real, but rather the result of mathematical constructs we create to describe the motion of many tiny particles, or are they actually fields?... #CFD #TurbulentFlow

(1) The family of k-ε turbulence models still remains among the most popular turbulence models for industrial applications. (2) Most known and recognized among this family of turbulence models is the Jones-Launder k-ε turbulence model. (3) The model supplies the flow equations with two additional partial differential turbulence equations. One for the turbulence kinetic energy and the other for its dissipation for the modeling of the entire turbulent flow field. (4) The model is in this sense closed (i.e. no flow parameters are specified a priori besides calibration constants). The following SlideShare from "AllAboutCFD" is a concise yet informative and communicated summary on the application of the k-ε model. It is based on "AllAboutCFD" post: "Understanding The k-ε Turbulence Model" - https://lnkd.in/eBRieUQU #turbulence #fluidmechanics #fluidynamics #aerodinamics #engineering

Chapter 13 covers the thermodynamics and kinetics of phase separation, including spinodal decomposition and droplet nucleation, derivation of the Cahn-Hilliard equation, and its implementation in phase-field modeling. Link is in the comment below.
