This CFD Simulation studies wind effects in relation to Building envelope pressure levels (Wind Load Analysis), Natural ventilation & Infiltration/exfiltration. It predicatively simulates pollutant dispersion (e.g Boilers, Outdoor Units, Fume hoods,etcâ€¦) hence allowing us to assess the environmental impact due to the migration of the mixed exhaust air towards the surrounding buildings and check for air entrainment at building intakes due to nearby exhaustd.
b.Air Distribution/Comfort Levels
At the single space level, this CFD Simulation predicts local conditions such as flow field, temperature & Relative Humidity distributions.This allows to optimize design parameters such as diffusers distribution, discharge angles and flow & size of air outlets/inlets.More, this also promotes advanced cooling technologies such as radiant cooling & Under Floor Air Distribution.In the case of Healthcare applications, the design of air distribution systems in patient rooms can be greatly assisted by computer simulations based on CFD analysis. This technique allows a study of the air flow and temperature distribution and the optimization of air delivery to achieve higher sterility in risk-affected areas. In the case of operating rooms, air quality is affected by many factors and the principal objectives are to deliver sterile air to the surgical site, ensure that inappropriate air mixing does not occur, air velocities do not adversely affect the operation and room comfort conditions are maintained. Computational fluid dynamicsanalysis allows a proposed operating room to be modeled and each of the variables to be tested to identify flaws in air distribution and make adjustments to achieve the optimum flows and temperature. Graphic displays show velocity distributions and temperature distribution, leading to specific placement of filters, diffusers and allow the effects of lights, staff and pendants to be identified
c.Fire & Smoke Modeling
Fire & Smoke CFD Simulations provide information on fire development and smoke migration inside buildings (Atriums, parking spaces, etc.) tunnels and subway systems. Theyâ€™re considered a basis for assessing performance of smoke management systems to ensure safe egress and optimize position of escape routes & smoke curtains.
d.Central Plant Airflow Simulation
At the industrial level, CFD simulations are used to model cooling towersâ€™ hot & humid plume on surrounding buildings, optimize the flow pattern inside plenums & false columns and optimize layout of built-up fresh air stations
e.Pumping station Design verification
For pumping stations, a CFD simulation is very useful in investigating air entrainment at pump suction bellmouth, visualizing flow conditions and checking for disturbances in sump and vortex formation.
