The Career Path to Becoming a CFD Engineer

Computational Fluid Dynamics has a growing scope in various fields such as automobile, aerospace, bio-medical, civil, marine, sports, etc. Many innovations in these fields involve the application of CFD. However, this domain is still in its nascent phase in India. This blog will shed light on what CFD is and how to become a CFD engineer.

 

 

What is Computational Fluid Dynamics (CFD)?

Computational Fluid Dynamics is the study of fluids and their characteristics. The technique uses numerical methods and computer science to predict the flow of fluids. Fast and reliable CFD improves engineers’ insight into fluid flow problems, enabling them to filter out bad designs and thus save valuable time and resources. With CFD, virtual experiments can be conducted, reducing the need for actual experiments in labs.

CFD analysis is multi-disciplinary. It involves the application of:

• Mathematics
• Flow physics
• Chemistry
• Advanced numerical methods
• Programming and computing skills

 

Computer science is indispensable to the study of CFD analysis. Both CFD hardware and software are used for CFD simulation. Hence, developing expertise in parallel computing, GPU and machine learning is important when studying CFD.

 

Who Should Specialise in CFD?

Anyone interested in aerodynamics, drag and IC engine simulation can specialise in CFD. You can also study CFD if you’re curious to understand how the fluid around you affects the pressure and velocity of any particular component.

 

How to Become a CFD Engineer?

 

 

If you wish to become a CFD engineer, you may consider taking the following steps:

 

Have Basic Subject Knowledge

The first step to starting a career in CFD is to be thorough with the fundamental subjects of the discipline. They include:

• Fluid dynamics
• Heat transfer
• Thermodynamics
• Transport phenomena
• Flow physics

 

Get the Necessary Programming Skills

A functional understanding of calculus and numerical techniques will assist you in understanding CFD codes. Familiarity with programming languages will help in this regard. You can start with MATLAB to program simple CFD codes. Once comfortable with MATLAB, you can move to Fortran, C++ and Python.

 

Be Familiar with Numerical Methods

To develop expertise in CFD, learning the numerical methods of solving partial differential equations is needed. The Finite Difference Method (FDM) and Finite Volume Method (FVM) are two methods of solving equations. Being familiar with their application to various problems may help you when facing similar situations in your career. 

Move on to Advanced Programming Skills

Once you’re familiar with the basic programming skills, you can move forward to mastering advanced programming languages such as GUI. This is the time to specialise in a particular domain or GUI. It can be:

• CFD using Ansys Fluent
• Aerodynamics using STARCCM+
• Advanced IC Engine
• HVAC
• Turbo Machinery

 

CFD Modelling of Complex Flow

When you’ve understood the mathematical fundamentals and are comfortable interacting with GUI, you can move on to some complex problems using advanced programming techniques. You may take up any of the two options here:

• Computational combustion using Python and Cantera
• Finite volume method for advanced CFD using C++

 

What are the Major Applications of CFD Analysis?

 

 

CFD applies majorly to the following areas:

• Automobile and Aerospace
• Production and manufacturing industries
• Turbo-machinery (fan, turbine, compressor, blowers, pumps, etc.)
• Thermal and nuclear power plant
• Combustion, fire and environmental pollution
• Heating and ventilation of buildings, cars, buses and civil aircraft
• Weather forecasting
• Defence and space applications
• Biomedical applications

 

Skills Expected from Job Seekers as a CFD Engineer

• Knowledge of Fluid Dynamics and Heat Transfer.
• Ability to perform fluid dynamics simulations and optimisation analysis.
• Ability to solve simulation convergence issues.
• Ability to validate simulation results by comparing them with test results.
• Knowledge of CFD solvers (Star CD/Fluent/OpenFOAM).
• Proficiency in CFD modelling, solver set-up and post-processing.

 

The salary of a CFD engineer in India ranges from Rs 3 lakhs to 11 lakhs, with a national average of Rs 6.5 lakhs. The average salary of a CFD engineer in European countries like Germany is around 51,000 euros.
