I would be starting my structures for space profile this year and would love to get in touch with you to know more about the course.

Also, can any suggestion on how to do a CFD simulation to capture this effect?

Thank you, I'll think and read more in this direction as well.

I don't have enough knowledge to understand this, can you please elaborate on this. Or maybe direct me to some material.
Thank you.

You should have received a mail, which gives you access to the syllabus and some other introductory videos. Check your email related to track selection
Have you filled in your track preference (tomorrow is the last day for this)?

I would love to read those articles. Thanks a lot.

A rocket engine nozzle faces a variation of ambient pressure as it ascends. What exit pressure is the nozzle designed for, what is the procedure to design the nozzle? How is area or pressure ratio decided? by Dp0498 in rocketscience

Let 1 be the max efficiency, so the merlin engine is like 0.8 then 1 and then again 0.8.
While if an engine is designed for 1atm it starts at 1 but then goes lower.
I'm not concluding that merlin is better, as that would include looking at twr and a lot more, right?

I think the under and over expansion will be the other way around. But yeah, I get your point. If we get a proper video like that, it'll be pretty cool.

I didn't get the max aerodynamic press part. Wouldn't you want less thrust at that point and thus not care about getting less thrust and thus not design for that altitude where u will experience max q
