Hi, I'm a fifth-year technical student, and I'd like to design a 125 engine. I have already taken many data as phases of unloading travasive compression ratio etc. I have difficulty finding a software to use to insert the data and find the engine graphics, the maximum pressure I need for the design of the biella, and understand that angle to give the travases so as to obtain a good washing. I would therefore need a free software xxxxx(because I have no money to spend) that helps me to do all these things and that let me see also the gases as they expand to see just the washing etc. Can someone give me some advice?
Thank you.

Excuse me, but all this maturing tesin stuff? but then for the master's thesis one thing should do?
However it seems to me a very specific field and particularly complex I do not know if you will find applications around the corner.
If you consider the idea of something easier
 
you would be my dream. but I don't know how to do it because at the end of important I just miss a software to use by inserting the 3d of the engine and that you pull out the fluid dynamics so as to understand that inclinations change die primary secondary travases and the third travase
 
However, solidworks also has a fluid dynamic analysis module but I am sincere, I do not have the skills to enter the data to interpret them and possibly take the relative corrections to the model.
my tesin for maturity was on turbocharged engines but I remember that I did something very generic and superficial even if at the time hours of fluid machines were many.

Do you have cfd simulations? bhe maybe if you spend a few tens of thousands of euros and you do special courses you can take it! It sounds weird.. .

Maybe you need a good book, I remember in past times a nice book was jacous dante!
 
a book is not enough to see all the things that make a software. and I read about it on the engine two times as we elaborate the 2t and two-time high-performance engines is that they do not specifically deal with calculations to find the beam width but only says that the exhaust light is good that it does not exceed 70% of the allotment.

I agree perfectly with you, but being a very specific field, or you find a motor designer who helps you, or maybe try knocking at some company that produces this type of artifacts.

I also think it's an oversized fur project for a technical institute. then that you can understand how to "turn smoke" only with a simulator can not be true, because of the two times they have designed tens between the 50s and the 90s... it is the simulator not there at that time.. .
 
In my previous work, having to develop a new two-time engine, we had to turn to an old motorcycle designer and talk to you about decades ago, where there was still the tecnigraph.
 
I don't know now but in my time of itis (80s) drawing books were filled with masses of motors of Italian companies known in the automotive and motorcycle industry, laws piaggio, benelli, fiat, alfa romeo, try to search in the library of your school maybe find good ideas.
 
Thanks again very kind help. I have one last question. reading "we process 2 times" I saw some tables of exhaust beams. I tried to take a 203 degrees of unloading and usually this value is reported to the pms right? but then there is another table with the maximum beams and for a motor that arrives at the 14000 turns it assumes a theoretical value of 142 degrees and this value however logical rigor I think refers to the pmi. same thing for the aspiration I took from the table a value of 203 that you think refers to the pms. would you confirm me? because knowing these values I was looking for a way to turn the grades into mm so in the design phase of the cylinder I understand more or less how high to make the lights. Thank you in advance.

My curiosity. the 3d of the engine to feed the software for fluid dynamics, did you do it with rhino?

I would like to design it there because I know how to use it well but if I understand that I can simulate with solidworks the design with that
 
Sounds more suitable for solidworks.
Rhino. is great with surfaces, but it is not parametric.. and I see it hard

Congratulations you already know how to design a 3d engine using two different software! chapeau.
 
If you can have all the solidworks modules, you can model the mechanical components, do a set, do physical simulation, do fem and with the ex floworks module you can do fluid dynamic gas/miscela analysis. Of course, knowing how to use everything is not easy, especially without theoretical vessels. There are several tutorials, and maybe even on engines ....so there is a chance to have a good package.

you will have to study a lot but it is my dream to succeed so I will succeed
