From external flow to white space, from grey-space thermal safety to transient resilience — boundary conditions calibrated with site-specific climatology, executed on customer-approved solvers, delivered in decision-ready form.
The quality of a CFD result is determined far more by the engineer's command of the physics than by the tool. That's why every model we run is calibrated against high-resolution climate data, the solver is chosen per scenario and specification, and the result is interpreted & packaged for real design decisions.
Input side — ERA5 reanalysis, local weather-station (e.g. DWD) ground-truth and ASHRAE n=50 design-day envelope establish boundary conditions on a statistical foundation.
Solver side — Steady-state (RANS) and Transient scenarios run on the same validated engineering backbone; mesh-independence, convergence and validation are reported in every deliverable.
Output side — Not just contour images: temperature, velocity, pressure and pollutant concentration are interpreted against acceptance criteria, pointing to exactly where the design needs to move.
Tool-agnostic flexibility — Selected from the Customer's Approved Software List: Cadence 6SigmaDC, ANSYS Fluent, OpenFOAM, STAR-CCM+, Cradle SC Stream or TileFlo — we adapt to your stack, not the other way around.
From early design through commissioning, we map thermal & airflow risk across the entire building envelope — external flow, white space, grey space, and transient response — all running on the same validated solver stack.
Atmospheric flow analysis for building and near-surroundings; generator exhaust dispersion, re-ingestion risk at air intakes, facade and rooftop equipment wind loading.
Airflow distribution across high-density rack layouts, hot/cold-aisle performance, ASHRAE TC 9.9 A1–A2 compliance and N+1/N+2 redundancy scenarios.
Local temperature peaks around UPS, battery, transformer and chiller rooms; summer-peak load (ASHRAE design day + full load) and battery thermal-safety envelope.
Time-resolved thermal response across the utility-fail → generator restart-attempts → catcher-generator chain; thermal mass, CHT & continuous-cooling exemption evaluation.
A holistic CFD sweep requires a complete scenario set. We organise every standard case under one roof. Each scenario is a mini-package that can be priced on a unit-fee basis, then combined per site classification (Hybrid / Core / Edge / Electrical-Rooms).
CFD output is only as reliable as the climatology beneath it. A four-step workflow produces a location-specific, statistically representative wind / temperature / humidity regime for every project — then feeds it to the solver.
30+ years of hourly ECMWF ERA5 data for the exact location; wind rose, stability classes, temperature/humidity distribution.
Bias correction against the nearest meteorological station; topography and urban-roughness adjustments applied.
ASHRAE Fundamentals n=50 temperature envelope; summer/winter extremes, safety-margined thermal loads.
Atmospheric boundary-layer profile, turbulence intensity, surface roughness z₀ — fed scenario-by-scenario.
CFD quality depends primarily on engineering competence — but the tool chosen must also match the client's specification. We work with every solver on the Customer's Approved Software List, and every deliverable cites the governing standards.
Solver is selected per scenario type (external / internal / transient) and per the Customer's Approved Software List on a case-by-case basis. Every final report documents tool selection, mesh summary, turbulence model, convergence criteria and monitoring-probe locations.
All deliverables are assessed against the ASHRAE TC 9.9 A1–A2 temperature envelope, Max SIT 35/40°C limits, VDI 3783-12 atmospheric dispersion protocol and EN/ISO ventilation standards. Acceptance criteria are locked with the client up-front.
Specification-aligned PDF report covering mesh, turbulence model, convergence, results and acceptance criteria.
Native solver file deliverable (optional); ready for future revisions in the client's own environment.
Executive slide deck for non-technical stakeholders; risk map + recommended decisions.
Layout / equipment recommendations for critical hotspots; re-run service available at unit rate.
Internal flow → layout optimization → transient is the sequence enforced by customer specifications. We lock this order at project start and de-risk the offer with a 15-day pre-analysis checkpoint.
Design criteria are matured jointly with the client during the simulation process; Alkazar positions itself not merely as a computation provider, but as a partner offering engineering support to the design itself.
