What maths would you need for mechanical engineering?

Click For Summary

Discussion Overview

The discussion centers around the mathematical subjects relevant to mechanical engineering, particularly in the context of preparing for Computational Fluid Dynamics (CFD). Participants explore various mathematical concepts and their applicability in engineering courses and real-world scenarios.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants suggest that multivariable calculus, differential equations, linear algebra, and partial differential equations are essential for understanding CFD.
  • Others propose that numerical methods, statistics, and Fourier transforms/spectral analysis are also important, especially for studying turbulent flows.
  • A question is raised about whether one needs to learn the proofs of mathematical concepts for their application in CFD.
  • It is argued that understanding the application of math and the physics behind the equations is more critical than knowing the proofs, particularly regarding numerical algorithms and stability criteria.
  • A participant inquires about recommended engineering math textbooks for reference, leading to a suggestion of "Advanced Engineering Mathematics" by Kreyszig as a comprehensive resource.

Areas of Agreement / Disagreement

Participants generally agree on the importance of various mathematical subjects for mechanical engineering and CFD, but there are differing views on the necessity of understanding proofs versus applications. The discussion remains open regarding the best approach to learning these mathematical concepts.

Contextual Notes

Limitations include the lack of consensus on the depth of mathematical understanding required for CFD and the specific applications of different mathematical tools in engineering contexts.

I mean when we're getting into higher level courses and real life, what are the more applicable subjects in math for mechanical engineering?

I'm not asking for myself but for a friend. He wants to get into Computational Fluid Dynamics and would like to prepare himself better during his undergrad years.

Computational fluid dynamics uses computers. But to understand the math you should know multivariable calculus, differential equations, linear algebra, partial differential equations, and a few other broad, general types of math. A strong understanding of calculus is really necessary for understanding the intricacies of CFD.
 
I agree with Travis_King but I would also add a few things.

First I would add numerical methods but that is probably obvious.

If your friend is going to be studying turbulent flows it will also be important to know some statistics and Fouirer transforms/spectral analysis.

But this is all stuff you can learn from the relevant classes in school.
 
By "knowing" does my friend have to learn the proofs of everything in that type of math?

Definitely not. CFD is an engineering tool so its the application of the math that really matters. When you look at an equation you should be able to understand what it is telling you about the physics of the problem, and you should understand how to implement numerical algorithms. Also for CFD it is important to understand certain stability criteria for the numerical scheme you are using but you don't need to know the proof/derivation of the specific stability criteria.

I don't do CFD but I believe a major part of it is understanding the various turbulence models so you know which model to apply in which situation and its important to understand the physics of the problem so you know which terms are important.
 
Whats a good engineering math textbook to pickup for reference? I read here awhile ago that somebody recomended some holy grail engineering math textbook where you'd be able to reference all the equations needed.
 
"Advanced Engineering Mathematics" by Kreyszig has just about anything you need to know for engineering.
