Mechanical engineering is considered to be a field where analytics and manual power is a necessity while computational powers are optional. But the actuality is vice-versa. Let me explain how:
According to the report published by the Ministry of Petroleum and Natural Gas on January of 2014, the transportation sector in India consumes 70% of diesel in which 28.25% of diesel is consumed by heavy trucks.
Data for the chart was taken from here.
As you can imagine, fuels like diesel and petrol are extremely vital and always in demand. Reducing the consumption of fuel will benefit a country economically and environmentally. But to do, we must first understand that making a machine consume less fuel is a mechanical problem. In the case of trucks, the shape of the truck and the weight they usually carry causes a high level of drag force to act on them.
Because of the drag force acting on the trucks, they have to burn more fuel. In other words, if we can improve the aerodynamic shape of the trucks to reduce the drag force acting on them, we can reduce fuel consumption. to do so, we must develop new designs and test them. This can be done to win three ways:
|Road test||Accurate||Expensive and time-consuming.|
|Wind tunnel||Cheap||Low level of accuracy. The circumstantial parameters are different in a wind tunnel and on-road.|
|CFD||Extremely cheap||Results are relative. CFD results are more accurate on supercomputers.|
From the table above, you can understand which method is more favored. A test design of a truck is going to cost a lot of money. A wind tunnel experiment is also favored in many cases. But the problem with wind tunnels is that when they test vehicles, they don’t take the reality factor into account. A test design in wind tunnels acts under a set of parameters whereas, on-road, they act under different conditions. In CFD, we can create as many designs as we want to and test them in different conditions.
While this is just an illustration, it proves that Mechanical engineering concepts affect real-world problems like economics and the environment. And to combat those issues, we usually involve CFD whenever there is flow mechanics involved.
Here are a few reasons why CFD is preferred by industries across the world:
Because of reasons such as the ones mentioned above, industries have already started to replace prototyping with simulation. According to the Financial Times, Jaguar land Rover is planning to remove physical prototypes from the early development processes by 2020 and rely on computer modelling instead and a lot of industries are planning to follow suit. This is why CFD is gaining popularity these days. And in order to be relevant to the industry, mechanical engineers are recommended to learn CFD in depth. Learning CFD will substantially increase your chances of securing a job in the core industry.

Advanced Turbomachinery Simulations for Mechanical Engineers
In this project, you will analyse the head impact on the car hood. You will learn how to set-up the case study by giving the required geometry transformations, boundary conditions, material models, contact definitions. Stress, strain, head impact coefficient(HIC) values will be calculated and studied in post-processing.
In this project, you will learn how to validate the elasto-plastic material model with the given stress-strain data. You will learn the extraction and cleaning of the stress-strain data point from the given curve. Then you will study how to evaluate the hardening curve and give material parameters input to the LS-DYNA software. Finally, you will understand how to extract the stress-strain results from the simulation and compare it with the given data.
This project deals with simulating the flow around a Mercedes Benz Actros truck with and without the trailer attachment, We will be studying the production of wake and how the trailer attachment affects the wake produced by the tractor and the effect this has on the production of drag on the vehicle. Suitable reports and plots will be used to measure the drag coefficient and to assess convergence. Various post processing techniques can be used to provide animations that clearly show the flow patterns.
