Introduction

The method of mathematically modelling a physical phenomenon involving fluid flow and solving it numerically using analytical prowess is known as computational fluid dynamics (CFD). Aerodynamics plays an important part in the manufacturing phase when an architect is tasked with developing a new vehicle, such as a winning racing car for the coming season. Aerodynamic processes, on the other hand, are difficult to quantify during the concept stage. Physical checks on product samples are typically the only way for an inventor to refine his designs.

Computational Fluid Dynamics (CFD) has become a widely used method for developing solutions for fluid flows with or without solid interaction, thanks to the advancement of computers and ever-increasing computational capacity. The study of fluid flow in terms of physical properties such as velocity, friction, temperature, density, and viscosity is carried out in a CFD software review. To evaluate the fluid flow, a CFD software tool employs a statistical model of the physical case and a computational procedure. The Navier-Stokes (NS) equations, for example, are used to define the mathematical model of the physical situation. Changes in both of those physical properties for both fluid flow and heat transfer are defined in this way. Furthermore, the precision of a CFD study is heavily dependent on the process's overall configuration. The mathematical model must be checked in order to establish an effective case for solving the problem. Furthermore, determining appropriate numerical methods is essential for generating a reliable solution. The CFD analysis is a key element in generating a sustainable product development process, as the number of physical prototypes can be reduced drastically. The key structure of the thermo-fluids investigation is driven by governing equations based on the conservation law of fluid physical properties. The three laws of conservation are the fundamental equations:

1. Conservation of Mass: Continuity Equation

2. Conservation of Momentum: Newton’s Second Law

3. Conservation of Energy: First Law of Thermodynamics or Energy Equation

In a closed system, these rules state that mass, momentum, and energy is stable constants. All, in essence, must be conserved.

Convergence in CFD

A highly qualified artist with the ability to visualise the finished product from the outset is needed to produce a sculpture. A sculpture, on the other hand, can start out as a simple rock and develop into an extraordinary piece of art. To produce the desired specific form, full incremental processing during the carving process is crucial. Convergence is a significant problem in numerical analysis. The flow of a fluid has a non-linear mathematical model of numerous dynamic models such as turbulence, phase transition, and mass transfer, and their convergence is strongly affected.

Applications of CFD

CFD occurs anywhere there is fluid. As previously reported, the first step in running a CFD simulation is to define an effective mathematical model of reality. Rapprochements and conclusions provide guidance for analysing the case in the computational domain through solution processes. CFD techniques vary depending on statistical equations, numerical methods, computational equipment, and post-processing capabilities. Since a physical entity can be modelled using a variety of statistical techniques, it can also be combined using disparate computational methods at the same time.
