Computational Fluid Dynamics & Finite Element Analysis

We model the physics
before you build the hardware.

OXCORE Engineering runs CFD and FEA studies for oil & gas, process equipment, and data center clients across the Houston area — so design decisions are backed by simulation, not assumption.

01 — Computational Fluid Dynamics

When flow behavior decides whether the equipment works.

CFD lets us solve the flow field inside complex geometries — multiphase separators, downhole tools, flare headers, pipelines — before anything is fabricated. We use it to find problems early, optimize performance, and cut the cost of getting it wrong.

Representative work

Three-phase separator slug study

A horizontal separator splits crude into oil, water, and gas while holding a water level that keeps gas from escaping through the liquid outlets. We model what happens when an upstream gas slug hits the vessel — predicting interface levels and where they need to sit to survive a given amount of slugging.

2016

OXCORE became the first firm to build a complete CFD model of a full downhole system of tubes and nozzles — resolving erosion rates inside each tube and at every nozzle, with sand concentration and overall distribution computed across a range of slurry flow rates.

02 — Finite Element Analysis

Stress, fatigue, and thermal answers you can put in a report.

FEA breaks a complicated part into elements we can solve numerically — the right tool when geometry and loading make a closed-form answer impossible. We use it for ASME vessel work, piping stress, and fatigue life where the margin actually matters.

Representative work

ASME vessel stress analysis

Elliptical heads, nozzle junctions, and discontinuity regions don't lend themselves to hand calculation. We build the model, apply the real loads and material properties, and resolve the stress field to code — so the design is defensible, not just conservative.

03 — The firm

A small Texas firm built around two hard tools.

OXCORE Engineering was formed in Katy, Texas in 2015 by professionals with decades of combined oil & gas and commercial experience. We've run studies for some of the smallest operators in Texas and some of the largest in Houston — and we keep the focus narrow on purpose.
