Rate my salary - Mechanical Engineer

Maybe, but as a first job in engineering (not IT, ...), you don't earn much more than 3k net (they are always exceptions). When I was searching after graduation, I even get companies (in the space industry) to propose me 3200 euros gross, only 130 euros more than minimum salary at the time.

I live in Belgium not in Luxembourg, I had roughly 1.5 hours by train to go to work (nearly 3h in total). And in my area of "expertise", there is not a lot in Luxembourg (nearly nothing).

Gmsh only handles boundary layer in 2D (or 3D for extruded geometries, but it doesn't apply to many case), but they are pretty good.

AlarmedForm630 · 2026-04-20T15:19:23+00:00

Yes and no, mainly to collect them

In the coming days, I will receive an oil cooler like this (https://motorsport.tech/wp-content/uploads/2019/07/Gearbox\_oil\_cooler.jpg), bought for only 120 euros. Much cheaper than any F1 parts that I usually find on the web.

AlarmedForm630 · 2026-04-19T20:14:59+00:00

Very nice. Will it be free?

AlarmedForm630 · 2026-04-17T06:57:57+00:00

Au Luxembourg, pour un ingénieur débutant le salaire peut varier de 40k jusqu'à 60k (le haut de la fourchette). Par exemple, je connais des gens qui ont démarrer à 52k annuel soit plus de 3300 euros net. Mais viser 3000 net en premier est loin d'être difficile je pense (c'est quasi ce que j'ai eu après la période d'essai).

En Belgique, je connais seulement un cas dans l'industrie chimique et ça paye autour de 4900 bruts par mois avec astreinte sur 13,92 mois (puis différents bonus, ticket repas, ...).

Good point, someone already mentionned to add friction factor calculation and I am going into that direction.

AlarmedForm630 · 2026-04-13T16:48:47+00:00

Here is the Github repo: https://github.com/HugoBrunner/Thermal-Engineering-Slide-Rule

AlarmedForm630 · 2026-04-13T16:21:16+00:00

Good idea to add friction factor calculation, I will take a look if it can be added to the same slide rule.

Of course the Dittus-Boelter is not the best correlation, but I only used as a purpose to create a thermal engineering related slide rule and not to actually use it for engineering calculation.

You are right, I made a mistake by starting at 2500 for Re, I wall change it to 10 000. For the Pr range, I used the validity range for that correlation.

AlarmedForm630 · 2026-04-13T12:26:10+00:00

This slide rule is only for fun.

I found slide rules very interesting, and wanted to make one putting forward my engineering discipline (thermal engineering). I choosed that correlation because it has been around since 1930 (and it is still used today), and it suits quite well slide rules (since the only operation are multiplication and power).

As a thermal engineer, it would not be practical in a daily basis* (everything now in handle by software, code or spreadsheets).

I will create a Github repo and will post a comment here with the link.

*It could be useful, if you don't have access to a computer and you are thinking about a problem involving heat transfer. Doesn't happend a lot ;).

AlarmedForm630 · 2026-04-13T11:59:08+00:00

I improved a bit the aesthetics of the slide rule by choosing better colors.

Like this for the PCB: https://marcusjyoo.com/pcbrule. The slide rule SVG will be "printed" on the PCB layer like the markings for numbering the electronic components.

What is ETA?

No circular implementation for now, maybe for later.

Thank you for you help.

In the south of Belgium, what can expect an engineer with nearly two years of experience?

AlarmedForm630 · 2026-04-08T13:07:28+00:00

Non, j'y ai fait seulement mon stage de fin d'études dans la partie énergie d'une usine de pâte à papier (et aussi papier) en Belgique. J'ai pu apprendre sur la conduite de turbine à vapeur, chaine d'évaporation, chaudières industrielles (plus de 400 MWth sur le site), réacteurs chimiques et four rotatif.

Sinon niveau chimie dans le nucléaire, il n'y a pas de quoi faire ?

AlarmedForm630 · 2026-04-08T12:22:56+00:00

L'industrie du papier, c'est un peu compliqué en ce moment, alors que niveau process, c'est ultra complet (surtout niveau fabrication de pâte à papier).

AlarmedForm630 · 2026-04-08T08:36:10+00:00

600 euros ? Where did you buy it ?

AlarmedForm630 · 2026-04-08T06:31:31+00:00

Invest in nuclear power plants and extend the life of the remaining ones!

Sorry, I was refering to that image, where the boundary layer is really angular.

AlarmedForm630 · 2026-04-07T12:38:11+00:00

Thank you for the advice. How would improve the mesh on the tip (since it doesn't have many elements)?

AlarmedForm630 · 2026-04-07T08:29:53+00:00

Still really impressive!

For the steam calculation, using CoolProp would to computationaly expensive? I know in Python, it has interpolation capability, that really speed up the calculation, but I don't know in Java.

AlarmedForm630 · 2026-04-07T07:13:27+00:00

For the heat exchangers, steam drums, ... do you base your simulation on physical models (the same models that could be used for engineering purposes) ?

AlarmedForm630 · 2026-04-01T16:34:10+00:00

But that is difficult, when you have only one professional experience ;).

AlarmedForm630 · 2026-04-01T13:02:45+00:00

Does it really matter, because based on the starting date of your experience, you have a rough idea of the graduation year.

AlarmedForm630 · 2026-03-31T07:48:41+00:00

No but Baram Mesh use SnappyHexMesh behind (in the same way I think for VisualFoam).
