Mechartés is a leader in evaluating effectiveness of a Smoke Exhaust System in a complex building like Airports, Malls, Museums, Auditoriums, High Rises etc. using the Computational Fluid Dynamics (CFD) Models. Our experience in using FDS (Fire Dynamic Simulator) in thousands of projects executed all around the world where smoke movement from the origin of fire in the occupied zone inside a building and smoke contamination in the interconnected corridors are simulated in order to design the Exhaust System to be capable of maintaining tenable conditions in the corridor used for evacuation. With CONTAM based Multizone Airflow and Contaminant Transport Analysis, we can investigate the impacts of various design decisions related to Ventilation System Design and building material selection, and to assess the indoor air quality performance of an existing building for our Customers. Finally, with evacuation modeling, using crowd dynamics, we have been providing a complete Simulation based Consultancy for Owners, Contractors and Fire Consultants.
Energy-efficient buildings are only effective when the occupants of the buildings are comfortable. Thermal comfort inside a building is defined by Temperature, Humidity, Thermal Radiation and Air Velocities. These parameters are accurately modeled by Mechartés using CFD (Computational Fluid Dynamics). Mechartés have been involved in numerous studies performed for very large infrastructure projects of international repute like Dubai, Muscat & Salalah, Mumbai, Mauritius International Airports, Opera house Dubai & Oman, Warner Brothers theme park-Abu Dhabi to name a few. We have even integrated a thermal comfort perception index based on human body thermoregulation mechanism in our CFD simulations to accurately describe human body temperature while taking into account metabolic activity & clothing insulation as input parameters which can provide results based on Predicted Mean Vote (PMV) & Predicted Percentage of Dissatisfaction (PPD) indices as defined in ANSI/ASHRAE Standard 55-2010.
Building regulations and other statutory instruments define strict adherence to building codes in Car Parks for health and amenity by ensuring critical containment of Carbon Monoxide (CO) emitted from exhausts of car engines. Analysis based on Computational Fluid Dynamics (CFD) can predict the fluid flow paths and concentrations of CO, as well as identify any dead zone for a given ventilation design. With a deep understanding of building codes followed in India, National Building Code (NBC), Europe like BS 7346 & Germany’s XXX, Dubai Civil Defense, Singapore Civil Defense, building codes of Oceania Region & ASHRAE, Mechartés have provided numerous optimum ventilation design solutions for our Customers all over the world.
Wind driven flows can have important consequences on structural integrity of buildings, natural ventilation & performance of equipment like Cooling Towers. With Computational Fluid Dynamics (CFD) Simulations, wind loads can be studied on high rise buildings with detailed information about harmonic vortex generated at the rear end of the building to the wind direction. These analysis can also be used to make preemptive decisions regarding natural ventilation design with suitable information (local wind velocity, convective coefficients, and solar radiation intensity) for orientation, site and location selection of buildings. Further, equipment like Cooling Towers and ODUs of Air-conditioner Units can see performance deterioration due to wind characteristics due to obstructions around the buildings which may increase recirculation of hot and humid air inside these equipment. CFD Simulations provides information that can be used by Contractors, Architects & HVAC OEMs to come up with installation methodology & designs that suitably reduce recirculation of hot air and help maintain the desired performance of these equipment
Equipment designed in Building & HVAC industry relies heavily on methodology that are analytical and have been refined through experience. However, new and innovative building designs with green technologies are becoming the norm, innovative solutions are required to make these buildings energy efficient. Numerical Simulation based analysis and design are increasingly able to meet requirements of Contractors, Architects and building Owners by providing practical feedback even at the conceptual stage of design. With these simulations, Mechartés is able to explore merits of alternative design without actually building the system and thus saving precious time and money. We have associated with many building & LEED consultants on projects where innovative design solutions have been provided to come up with a System Design which has not only met design expectations but at times even surpassed them.
