As crucial domestic and international transport nodes, airports experience an influx of people passing through, waiting for their flights, and working engrossingly to ensure safe and secure travel. All these factors make it imperative to maintain a certain comfortable environment in the airports.
One of the key components of public comfort in airports is efficient air conditioning systems. However, their installation and maintenance are quite challenging due to airports’ large and complex spaces, high occupancy levels, variable loads for different times of the day, etc.
In this context, Computational Fluid Dynamics or CFD services are well-equipped to maximize air conditioning efficiency and enhance comfortability in airports.
In this article, we will explore how CFD services combined with precision engineering can play a vital role in optimizing air conditioning systems inside airports.
CFD services refer to using computational fluid dynamics (CFD) tools and techniques to analyze fluid flow and heat transfer in various industries. It also involves optimizing airflow and temperature distribution for HVAC to enable these systems to function more efficiently.
CFD services have been proven to be speedy, affordable, and accurate. They can also provide customized solutions and optimizations of complex systems.
These steps in CFD services can help optimize air conditioning systems in airports:
To simulate and analyze various aspects of air conditioning systems in airports, a virtual model is created, which is a computer-generated replica of the physical system or environment, also known as virtual modeling.
The virtual modeling begins with collecting relevant data about the space, such as occupancy level, floor plans, HVAC systems specifications, and other pertinent information. This information should be accurate to make sure accuracy of virtual modeling and simulation as a whole.
Generating 3D Model
In the next step of the CFD services, a three-dimensional (3D) Model is created using advanced computer programs such as computer-aided drawing( CAD). This 3D model is an exact representation of the space of airports and other elements of airports that may have any influence on the air conditioning systems of airports, such as terminals, waiting areas, etc.
3D models should also include and integrate HVAC system designs and their specifications, such as ductwork, supply diffuser, etc. The insertion of specification and design of HVAC systems into virtual modeling should be based on the actual specification and design of the airports.
Mesh generation is significant for CFD services of airports to maximize their air conditioning systems because it allows engineers to explore models more accurately. It involves a process of dividing virtual models into a small number of cells, also known as mesh or elements, to apply fluid mechanic equations to analyze systems precisely at each cell.
The mesh generation begins with defining meshing parameters, such as mesh size, types, and other related parameters, according to the requirement of analysis and complexity of models.
Methods of creating the mesh
Then, the mesh is created with the help of different computer algorithms and methods, such as structured methods, unstructured methods, and hybrid methods, according to the requirements of analysis.
In the structured method, cells are rectangular and hexahedral and aligned with the modeling geometries, which is good for models with simple geometries and accurate results.
In the unstructured method, cells are usually irregular, such as triangles and tetrahedra, which are more flexible and can work with complex geometries and systems. As the name suggests, it is used for models that have irregular curves and geometries.
The hybrid method involves both structured meshing and unstructured meshing. It creates cells, both regular and irregular, in the same mesh, being flexible and able to handle different regions of geometries.
According to the types and sizes of virtual models, one of the above methods is chosen to create the mesh.
Once the mesh is created, it is checked for quality and numerical stability. Based on that, it is further optimized to improve its accuracy in certain mesh geometries.
After model creation, mesh generation, and definition of boundary conditions, the model is ready to be simulated. The model is imported into the CFD tool, and the governing equations of fluid mechanics that describe fluid flow and heat transfer, such as Navier-Stokes equations, are formulated.
To analyze airflow behavior within the space, the equation is solved at each cell of the mesh and calculates airflow velocity, temperature distribution, and other parameters throughout the space.
Once the analysis of the CFD services is completed, the results are analyzed within the space to understand airflow patterns and temperature distribution. CFD programs enable engineers to analyze results visually by representing velocity vectors, temperature contours, and streamlines to understand results.
Finally, based on the analysis result, CFD consultants provide solutions for optimization and improvement in air-conditioning systems, such as design modifications, ductwork configuration, air outlet placement, etc. By doing this, they maximize the efficiency of air conditioning systems in airports.
As a pioneer company in CFD services in India, Mechartes did a comprehensive case study of one of the most vital projects: the CFD thermal comfort analysis of Chatrapati Shivaji Aiport, Mumbai.
By extensive CFD analysis, we examined the effectiveness of designed air conditioning systems in full load and partial load conditions of “level 2” of Chhatrapati Shivaji Airport.
CFD services are valuable ways to enhance and maximize air conditioning systems in airports as they are able to analyze and understand airflow dynamics, optimize HVAC systems design, enhance air quality and ventilation, and create energy-efficient environments.
With CFD services, airports can ensure passengers’ comfort and improve operational efficiency. But to achieve that, it’s a matter of expertise and experience.
