CFD Simulation
Energy models tell you the annual numbers. CFD shows you what the air is actually doing — velocity, temperature and comfort, point by point, in every occupied zone.
Zone-level energy models average each room into a single air node — fine for annual energy, blind to stratification, draughts and dead zones. Our Computational Fluid Dynamics studies in COMSOL Multiphysics and OpenFOAM resolve the full 3D air-flow and temperature field, so comfort problems and HVAC design questions are answered before installation — not after the complaints arrive.
Full 3D velocity and temperature fields resolved into PMV/PPD, draught rate and vertical stratification maps to ASHRAE 55 / ISO 7730 — for offices, atria, auditoria, mosques and industrial halls.
Diffuser selection, placement and throw verification; mixing vs displacement strategies; short-circuiting and dead-zone detection — validated against design ADPI targets before anything is installed.
Conjugate heat-transfer modelling of radiant floors and ceilings, chilled beams, heat exchangers and equipment enclosures — coupled conduction, convection and radiation in COMSOL.
Stack and cross-ventilation performance, operable-window strategies and atrium flows — proving a passive design works before you commit to it.
Age-of-air, CO₂ and contaminant-dispersion studies to verify fresh air actually reaches occupants — supporting WELL, LEED IEQ and infection-control reviews.
Droplet-evaporation and outdoor/semi-outdoor cooling simulations for courtyards, terraces and hot-climate comfort interventions, with humidity and comfort mapping.
We work in COMSOL Multiphysics for coupled heat-transfer and multiphysics studies and OpenFOAM for large ventilation and air-flow domains. You receive velocity, temperature and comfort-field visualisations, section plots and a plain-language engineering report — conclusions your design team can act on, not just colourful contours.
