Computational fluid dynamics (CFD) is a collection of methods that assist computers provide computational simulations of fluid movements. The three fundamental concepts that can be used to identify the physical properties of any fluid are i) energy conservation, ii) Newton's second law, and iii) mass conservation. These fundamental laws can be used to explain the flow issue. The fluid behaviour in the flow region was represented by mathematical equations, which were typically in the form of partial differential equations. Some CFD methods are used to represent the solutions and interactive behaviour of solid limits with fluid or interaction between fluid layers while moving [1].
CFD converts these differential equations of fluid flow into numbers, and these numbers are useful in time and/or space, allowing a numerical image of the entire fluid flow [2]. CFD is effective in assessing system behavior, as well as beneficial and creative in system design. It is also effective in investigating the system's performance measures, whether for the purpose of increasing profit margins or improving working safety, among other benefits [3].
CFD methods are now commonly used in a variety of disciplines, including vehicle design, turbo machinery, ship design, and aircraft manufacturing. It also has applications in astronomy, biology, oceanography, hydrocarbon recovery, architecture, and weather. To conduct CFD analysis, numerous numerical algorithms and tools have been created. Because of advances in computer technology, numerical modeling for physically and geometrically complicated systems can now be assessed using PC groups [4]. Supercomputers can perform large-scale models of various fluid flows on networks comprising millions or trillions of elements in a matter of hours. It is totally inaccurate to believe that CFD depicts a developed technology; there are numerous unresolved issues concerning heat transfer, combustion modeling, turbulence, and efficient solution methods or separation methods, among other things. The coupling of CFD and other disciplines required thus, the primary aim of this issue is to cover an important gap in this field [5].
Energy efficiency is one of the most important features of mechanical design. Geared transmissions are widely used in a variety of industrial applications, and increases in efficiency translate into a variety of benefits, such as reduced pollutant emissions, improved system dependability due to lower operating temperatures, and increased power density [6-7]. The ability to assess multiple options throughout the various stages of the design phase is critical to achieving these goals. Computational Fluid Dynamics (CFD) in particular may be used for analyzing the issue of interest, overcoming the limits of analytical equations.
These methods are now used in almost every field, from engineering to medical research. Several significant factors are taken into account in hydrodynamics:
• Propulsion and opposition
• Maneuverability
• Sea keeping
• Design of the propeller Additional uses, such as pipes, etc.
• A significant time and money savings in new designs.
• There is an opportunity to examine several issues to which the experiments are quite challenging and expensive.
• The ability to examine a system under conditions that are beyond its capabilities is provided by CFD techniques.
• There is essentially no limit to the depth of detail.
• The product gains worth in addition. The ability to produce various graphs makes it possible to evaluate the features of the outcome. This encourages purchasing a promotional strategy.
On the other hand, applying numerical models to gears, where the topology of the domain varies during operation, is a difficult undertaking that requires the implementation of customized mesh handling techniques. The power losses of a spiral bevel gear were numerically investigated in this article using an open source tool. The numerical models' predictions were compared against experimental data. The technique used demonstrates a good computational effort, making it beneficial for parametrical investigations and, thus, suggests being an excellent tool for analyzing the efficiency and lubrication of gearboxes.
