The ultimate goal of any Mechanical Engineer would be to secure a job that is related to the mechanical engineering field that yields a better salary. But, changing of streams such as jumping to the IT industry after mechanical engineering occurs only when there is no idea of specializations within the field of Mechanical Engineering that could get the fresher, that much needed job.

What Is Computational Fluid Dynamics Or CFD?

Computational Fluid Dynamics or CFD is a science of predicting fluid flow, transfer of heat, chemical reactions and other related phenomena by solving mathematical equations using a numerical simulation.

Why Do They Refer CFD As A Flow Simulation Technique?

Yes! CFD has advanced itself to a greater extent where the flow of fluids around a structure or through a product can be analyzed based on computer simulation techniques. In lay-man terms This simulation technique creates a mini model of the structure or the product on a computer screen which enables the user to analyze the structure or a product with greater detailing.

So, What Do I Gain By Simulating A Product Or A Structure?

The main agenda of this simulation technique is to accelerate product development cycle.  Mechanical designers/engineers from the best companies around the world implement this technique at a very early stage of the product development cycle to analyze the product/structure  designed by them in order to meet client’s requirement. CFD simulation helps Mechanical Engineers to calculate-

  • Mass-flow rates
  • Pressure drops
  • Heat transfer rates
  • Fluid dynamic forces such as lift, drag & pitching moments and much more

How Has Modern CFD Methods Transformed Itself Over These Years?

CFD methods have always remained the same, except for its introduction to computers and a large-scale automation processes. This has resulted in increased levels of design accuracy and it provides deep insights on the flow of fluids in and around a structure or a product even before arriving at the final design. This automation in CFD techniques have brought down the risks involved while developing a Thermal Power Station or a fluid based product like the petroleum extraction dock found in oceans.

 Biggest Advantages Of CFD-

  • The use of CFD technique in design helps Mechanical Designers/Engineers to use as few physical models/prototypes as possible. In fact, many designers do not use physical prototypes at all to design a whole structure or a product.
  • The testing of prototypes/models is brought down to a minimum number since the CFD techniques by default tests the structures/products for obstructions.
  • It has drastically brought down the factors such as Time to Market & Cost to Market of the structure/product.

 What Sort Of Fields Use CFD Techniques Or What Is The Industrial Applications Of CFD?

CFD is used in almost all the Mechanical Engineering field of work and it is majorly used in Civil Engineering field as well. Some of the major industrial applications of CFD is as follows-

  • Aerodynamics in the field of Aeronautical/Aerospace Engineering
  • Industrial Fluid Dynamics in the fields of Mechanical/Marine/Aero/Civil/Chemical Engineering
  • Fluid Structure Interaction in the fields of Civil/Structural/Marine/Aero/Mechanical Engineering
  • Heat Transfer
  • Hydrodynamics especially in the construction of dams, reservoirs, canals & river linking projects
  • Multi-phase flows precisely in Ocean Engineering & Petrochemical Engineering

What Are The Benefits Of Using CFD Techniques?

  • Extremely low cost of designing while deriving data from physical experiments can be very expensive both in terms of execution and resource requirements (human & material)
  • Costs of designing/simulations with CFD techniques are going to be even more less expensive as the computers get more powerful in the future
  • CFD simulations can be performed very quickly and it provides a quick turnaround data during the initial stages of design process.
  • Some flows like Hypersonic flows cannot be tested in physical conditions due to the risk of radiations and CFD enables the designers to theoretically simulate any physical condition under the skies
  • CFD possess the ability to isolate a specific phenomenon from the design during testing unlike physical processes
  • CFD also enables the designer/analyst to examine a large number of geographical locations including the area of interest and it never fails to yield comprehensive flow parameters for examination of the structure/product.

Where Can Be CFD Simulation Techniques Applied?

  • CFD simulations are used in figuring out malfunctions of HVAC designs
  • CFD validates the number of exhausts & diffusers in a structure/product
  • It analyses the flow rate, temperature of supplied air to meet design criteria

Some Real Time Applications-

  • Vestibule Smoke Systems
  • Smoking lounges in Airports, Railways Stations, Shopping malls & Hotels
  • Displacement Ventilations Systems
  • Raised Floor Systems

What Kind Of Jobs I Might Get If I Lean CFD?

Top Mechanical Engineering Companies like Caterpillar, Elon Musk’s Space-X & Tesla are looking to hire Fluid Mechanics Engineers to work on challenging engineering and geoscience problems for their upstream business. The position-holder will be expected to apply physics-based models and utilize knowledge of multiphase fluid flow dynamics.

Responsibilities will generally include (This is subject to change based on the companies)-

  • Work with computational scientists and engineers to develop and deliver computational tools, models, algorithms, and software in the area of multi-phase fluid flow
  • Create and maintain infrastructure to automate simulation preparation and execution including processing and analyses of simulation results
  • Design, build, and execute parametric and uncertainty analysis studies using simulation models
  • Create tutorials, documentation, training material, and case studies

The usual salary packages that these companies offer varies between 7 Lakhs INR PA to 15 Lakhs INR PA
