Complete CFD services hub for water treatment, thermal engineering, electronics enclosures, and industrial process optimisation. Explore hydraulic CFD, heat transfer simulation, and enclosure thermal design by topic.
At Reynolds & Bauhm, we do not simply run simulations — we deliver engineering decisions. Our CFD services bridge the gap between theoretical design and real-world performance, letting you optimise hydraulic efficiency, thermal reliability and process output before a single component is fabricated. Whether you are refining a dissolved air flotation unit, validating an electronics enclosure for desert deployment, or troubleshooting heat-exchanger fouling, our simulations provide the quantitative insight required to de-risk your investment and accelerate project delivery. With chartered engineers, global project delivery and a performance-guaranteed methodology, we are your technical partner from initial concept through to design sign-off.
By solving the governing equations of fluid motion, heat transfer and species transport in a virtual environment, CFD turns design assumptions into evidence — and lets you:
Evaluate multiple design iterations rapidly, without the expense of physical mock-ups or pilot-scale trials.
Reveal dead zones, thermal hotspots, cavitation risk and recirculation patterns that conventional design rules cannot predict.
Fine-tune diffuser layouts, baffle configurations, fin geometries and flow paths to cut energy consumption and maximise throughput.
Produce validated simulation data to support environmental permits, building regulations and safety-case submissions.
Present high-fidelity visual evidence — velocity contours, thermal maps and particle traces — to communicate design intent to investors, regulators and review panels.
Resolve design questions in parallel with procurement, compressing the programme from concept to commissioning and cutting time-to-approval.
Behind the design sits a full modelling toolkit — CFD, process simulation, biokinetic (ASM/ADM), reaction-kinetics, hydraulic, limnological and data-driven digital-twin modelling. We pick, or combine, the disciplines that answer your question and validate them against real data.
Explore Scientific ModellingComputational Fluid Dynamics turns a design assumption into evidence — so the steel is cut once, right.
Most water-treatment performance problems are hydraulic: a clarifier that short-circuits, a DAF contact zone with a central jet and dead corners, a reactor that channels, a mixer that shears floc, a heat exchanger that stratifies. You cannot see any of it from a P&ID, and by the time it shows up on a commissioned plant it is expensive to fix. CFD reveals the flow field — velocities, mixing, residence-time distribution, temperature and particle paths — before fabrication, so the geometry can be corrected on screen rather than in steel. It is the difference between hoping a design works and knowing it does.
Contact-zone hydrodynamics, white-water distribution, short-circuiting and RTD, rapid-mix and flocculation G-values, sludge-blanket behaviour, aeration and oxygen transfer, thermal stratification and heat exchange — single and multiphase.
Formal mesh-independence studies (coarse/medium/fine, <2% target variance), validated turbulence closures with proper y+, Eulerian multiphase for bubbles and solids, and convergence to normalised residuals below 10⁻⁵ with mass imbalance under 0.1%.
On a UK brewery DAF, CFD-guided manifold and baffle changes lifted TSS removal from 78% to 94% and cut ferric dose 62% — validated over months, not a commissioning-day peak.
Read the case studyA few days of simulation routinely save a redesign, a chemical over-spend or a capacity shortfall. CFD de-risks new build, validates upgrades and settles “will it work?” before money is committed.
The same methods de-risk any geometry where flow, mixing or heat transfer drives performance — DAF contact zones, clarifier inlets and launders, aeration grids, rapid-mix and flocculation chambers, pump sumps, heat exchangers and cooling circuits.
Each study is delivered as a concise engineering report — annotated velocity, RTD and temperature fields, a quantified comparison of design options, and the specific geometry, baffle or dosing changes your team can implement immediately.
