Alhamdulillah, this CFDSOF application, having been developed by the AIR Group since 1997, has been benefitted from and applied in the educational, research and industrial fields.
Computational Fluid Dynamics (CFD) is a specialized branch of science in Mechanical Engineering focusing on energy conversion. In general. CFD is a method employed to solve any technical problems involving a fluid flow and other related phenomena: air circulation, heat transfer, and combustion within a combustion chamber with a chemical reaction.
Whatever issue related to fluid flow activities such as gas or air in liquid form may become the scope of the study that we can solve by employing a CFD approach. For instance, we can apply this method in the field of aerodynamics. If we want to buy a car, we can find information explaining the characteristics of cars’ aerodynamics, such as the difference between trucks and sedans. Sedans are more aerodynamic. Therefore, cruising on a sedan will be easier with fewer “obstacles.” Many aerodynamic issues can be predicted and solved through CFD science. In the field of sailing vessels. A vessel sailing on a sea will most certainly encounter obstacles that can be identified with CFD.
Usually, a general engineering problem will be theoretically and analytically solved. However, when theories cannot develop a solution, we can resort to laboratory examinations or experiments equipped with tools to measure and study the problem. Moreover, there is a third method, a computational method, namely mathematical solving of non-linear differential equations with the help of computers. In that experimental method, the data retrieval is actual. Meanwhile, in a CFD, we simulate a situation based on a mathematical simulation. It gives us several advantages: it is faster for us to retrieve data that can further be explained through several experimental tests and numerical methods.
Moreover, since the data is retrieved faster, they come down with a more economical cost. We can get them without having to install software and tools, spend much time, and employ human resources. In addition, CFD can help us simulate a situation on things that we cannot obtain experimentally such as measuring an aircraft during the flight or measuring something with a very high temperature where any measuring devices are not applicable.
To date, there are so many software programs. They look as if they were user friendly. In CFD, the data accuracy that we obtain depends very much on experience, expertise, and analytical thinking capability when using this application. When entering the data during the initial stage, we must understand the contents of the data that we input. Then, we process them. In the final stage, we have to assess whether the simulation results are adequate or not. If not, we must be careful not to distort the results.
Moreover, when presenting the results of the analysis with a CFD, we are required to employ our good interpretation skills. Not only it’s about CFD software, but it’s also a science of success which involves three main keys: software, hardware and brainware controlling the computing systems. In the end, the quality of the output results will depend on the inputs.
CFD innovations are beneficial to support many kinds of works. For instance, CFD is used in the field of coal-fired power plants requiring the disposal of pollutant waste to not be widespread and negatively impact the surrounding community. To avoid this situation from happening, we can simulate the estimated height of the using CFD. Our broadly applied.
CFD is specified according to the field of the uired science. For instance, in the fields of architecture, both accuracy and level of ease of use are required. In the aerospace and automotive fields, CFD is used to analyze external aerodynamics and engine performance. CFD also plays its role in manufacturing a model turbine, fan, and propeller in the equipment manufacturing industry. In fact, in the chemical processing industry, CFD plays an essential role in the process of combustion modeling, filtering, and drying.
