Real Interview Questions Every Aspiring CFD Engineer Should Know

logo

Skill-Lync

Are you a CFD engineer struggling to land your dream job? You’re not alone.  

The path to securing a position in this competitive field can feel overwhelming, especially when you're unsure of what to expect in interviews.  

You've put in the hard work to master the technical skills, but when it comes to the interview, the anxiety of facing unknown questions can be a major roadblock.  

What if you could walk into that interview room fully prepared, knowing exactly what kinds of questions top companies like Cyient are asking? 

This blog is here to help you do just that.  

We've gathered real-time questions straight from the interviews of CFD engineering roles to give you a clear edge.  

These are not just theoretical questions but the actual challenges you'll face, giving you a chance to hone your knowledge and walk into your interview with confidence. 

Let's dive into the questions that can make or break your interview. 


1. Can you explain how gas turbine engines work? 

Gas turbine engines operate by drawing in air, compressing it, mixing it with fuel, and igniting it. This process creates high-pressure exhaust gases, which spin the turbine and generate power. They’re commonly used in aviation and power plants. 


2. What are the practical applications of thermodynamics? 

Thermodynamics is the science of energy conversion. It’s applied in everything from designing engines and HVAC systems to power generation and even understanding how refrigerators and air conditioners work. 


3. What are the basics of thermodynamics? 

Thermodynamics revolves around four main laws that explain energy transfer: conservation of energy, entropy, and the principles governing temperature and pressure changes in systems. 


4. How does a gas turbine generate power? 

In a gas turbine, power is generated when compressed air is mixed with fuel and ignited in the combustion chamber. The expanding gases drive a turbine connected to a generator, which converts mechanical energy into electrical energy. 


5. What cycles are involved in gas turbines? 

The Brayton Cycle is the primary cycle used in gas turbines. It involves three stages: compression, combustion, and expansion. The working fluid (air) passes through these stages to produce work.

Bonus: Here are some additional questions to help you crack interviews at other companies like EQuad.  

1. How can cavitation be eliminated in a pump? 

Cavitation can be eliminated by increasing suction pressure, reducing pump speed, or lowering the fluid temperature. These methods help prevent vapor bubbles from forming and collapsing in the pump, which causes damage. 


2. Why isn’t a centrifugal pump called a positive displacement pump? 

Centrifugal pumps don’t move a fixed volume of fluid per revolution like positive displacement pumps. They rely on fluid velocity and pressure differences to operate, which is why they aren’t classified as positive displacement pumps. 


3. What is a combination thrust and radial bearing? 

This type of bearing handles both radial (perpendicular) and thrust (axial) loads, commonly used in turbines and pumps where the shaft requires support in multiple directions. 


4. What are the speed types of flows used to identify Mach number? 

The types are: 

Subsonic (Mach < 1) 

Sonic (Mach = 1) 

Transonic (Mach 0.8–1.2) 

Supersonic (Mach > 1) 

Hypersonic (Mach > 5) 


You've invested so much in your career to reach this point—don’t let the interview be the stumbling block.  

With targeted preparation and insight into the exact questions being asked, you can transform interview anxiety into a powerful opportunity.
