While designing combustion systems, flame speed plays an important role in determining their performance. In this module, you will learn how to calculate flame speeds. Note that this parameter depends upon the type of reaction mechanism that is being employed and the thermodynamic conditions in the combustion chamber.
You will also perform a sensitivity analysis that helps you determine which of the elementary reactions are going to affect the flame speed the most.
In this module you will learn the following topics:
In this module, you will be trained in the core concepts that are used while simulating combustion in complex 3D geometry. Here you will learn about the current trends along with the cutting edge tools that are used in the industry.
Flame Temperature
Highlights
Combustion Efficiency
Highlights
STIFF ODE
Highlights
Auto Ignition
Highlights
In this project, you will be exposed to the Cantera reactor network and its uses in solving various models. The reactor network allows you to calculate the expansion/compression work, heat transfer, mass transfer, and surface interaction with the environment. The auto-ignition gives the time required for combustion to take place and to control it can be beneficial for controlling pollutants as well as for complete combustion.
Sensitivity Analysis
Highlights
The correct description of chemical changes requires the application of reaction mechanisms consisting of several hundred or thousand reactions. This means that a huge number of parameters describes the chemistry of the combustion process. Hence, the application of the sensitivity analysis techniques is very useful for its understanding of those parameters.
Detailed chemical models are too big for many practical combustion simulations. Sensitivity analysis can be used for mechanism reduction, that is, finding a smaller model that produces similar predictions for some of the variables (i.e., species concentrations and temperature).
Flame Speed
Highlights
The flame speed is the measured rate of expansion of the flame front in the combustion reaction. The flame speed of fuel is a property that determines its ability to undergo controlled combustion without detonation. This project is the study of flame speed by considering the effect of temperature, pressure and concentration on it.
Reaction Reduction
Highlights
This detailed mechanism for methane-air combustion(GRI3.0) is probably the most famous one. It comprises 325 reactions and 53 species. The reduced mechanisms include only the top reactions and the associated species. The reduced mechanisms with a certain number of species are able to adequately simulate the ignition delay, sensitivity problem. Such a reduced mechanism saves a lot of computational resources as well as time.
Through this advanced course, you will learn the application of Computational Fluid Dynamics (CFD) theory on internal flows with special focus on simulating the Engines (S.I Engines and C.I Engines). Students will be introduced to CONVERGE STUDIO which is used specifically for setting up the case for engines.
Working on CONVERGE STUDIO will help you study the inside workings of an engine, from fuel injection, compression, spark ignition to combustion and flame propagation. Converge has an added advantage of automated meshing that helps save time.
At the end of this course, you will be able to set up any internal flow problem, clean up any complicated geometry, and model turbulence, combustion, and spray. You will also learn the theory behind the concepts of turbulence (RANS), combustion, and spray.
In this module, you will learn how to set up a CFD simulation using CONVERGE CFD. You will be provided with step-by-step instructions on the following: CAD import and cleanup Decomposing the model into boundaries and volumetric regions Inputting valve timing Choosing turbulence and combustion models Running the case in a parallel environment Post-processing
In this module, you will learn surface preparation in complete detail. Specifically,
In this module, you will learn the following concepts:
Initializing pressure, temperature, and species concentration in the intake, exhaust and fire deck regions
Disconnect triangles
Valve timing and the concept of minimum lift
Valve profile input
In this module, you will learn how turbulence is modelled and simulated in a state-of-the-art CFD solver. You will learn about the different classes of turbulence models and understand their merits and demerits. In this module, you will also learn about,
RANS approach to model turbulence
Comprehend the math involved behind RANS and its derivations
Learn theory on different types of turbulence models available (RNG k-ε, k-ω SST, etc.) and appreciate which model is suitable for what type of application
In this module, you will learn how the SAGE detailed chemical kinetics solver works. In addition to this, you will also learn how to use the Shell CTC combustion model.
To design efficient engines, one needs to have a firm grasp of emissions modelling. You will learn about the Hiroyasu soot model and the Zeldovich nox model and apply them in engine simulations.
Throttle Body
Highlights
The objective here is to simulate flow past a throttle body under steady state and transient conditions. Your task is to study the effect of the valve dynamics on key flow quantities.
Diesel Engine
Highlights
In this project, you will run closed cycle simulations of the CAT3410 engine using two different piston bowls. You will be looking at the effect of piston bowl shape on the final solution.
Fuel Injection
Highlights
Clean up complex CAD model using CONVERGE STUDIO
Assign proper boundary and initial conditions
Setup appropriate physical models (spray, turbulence, combustion, and emissions)
Running simulations in parallel
Runtime results visualization
Post-processing results
Creating cut views, iso-surfaces, images, and animations
You will also focus on analyzing the data obtained from your simulation using line plots. You can find an example below. Last but not least, there is a reason why CFD is called colourful fluid dynamics. Here are some visualizations that beautifully convey the complexities of the various physical phenomena that you can expect in an I.C Engine.

The course that you studied in college was designed years ago and does not take into account the current market trends or what the industry expects from graduates. Our courses have been designed in consultation with industry experts and leading academicians. Skill-Lync courses are geared to help you find employment as soon as you complete the coursework. This is possible only because of the projects that you will complete as part of your curriculum, in your college you might have done one major and one minor project. But, each module in a Skill-Lync course has a corresponding project, and these projects are industry-oriented. Which means that if you were to look at the project that an engineer at a top OEM is working on, it will be similar to a Skill-Lync project, the only difference being the scale of the project.
Simply put - there's a world of a difference between what you have studied at your college and what you will get trained in when you study at Skill-Lync.
You will have an edge over your peers by working extensively on industry-relevant projects, practice on tools and software that will set you apart and help you in getting ahead of the competition.
