The Stack Effect Analysis is a buoyancy driven phenomenon that commonly occurs in high-rise buildings.

One of the main factors for this phenomenon to take place is temperature difference between the interior of the building and the external environment. The temperature difference between inside and outside of a building causes a difference in density which eventually leads to the pressure difference and arouses the air to flow inside the building (infiltration) or outside the building (ex-filtration).

Mechartés is a leader in evaluating effectiveness of a Smoke Exhaust System in a complex building like Airports, Malls, Museums, Auditoriums.

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.

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.

The thermal performance of data centers is numerically studied for different configurations of computer room air conditioning (CRAC).

A Data Center and its components often make up the core of an organization’s IT System. Sometimes, due to insufficient/improper cooling of data center, it experiences “Hot Spots”. A hot spot can be defined as a location/place where the cooling is not been taking place properly. This results in insufficient cooling and consumption of more energy and failure of servers. Hence, the data centers must be cooled properly.Mechartes use CFD Simulation to predict the detailed flow field in the critical areas in data centers and assist you to check the effectiveness of cooling within the racks and hot & cold aisles.

Building regulations and other statutory instruments define strict adherence to building codes in Car Parks for health and amenity.

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, 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.

In HVAC application in large commercial building or in industrial processes like power stations, cooling towers and chillers play a very significant.

The placement and air intake for the cooling towers and chillers are an important aspect and can decide their working efficiency. Cooling Towers reject heat using evaporative cooling which is dependent on the moisture present in the ambient air. Sometimes, some portion of this air comes back again in the cooling tower inlet (i.e. recirculation).
