Can you help to write a MATLAB Code to compute oblique shock angles?

What is given, what is unknown ?

[Eda Deniz Soydinc]

Hi I have to change beta continually until I reach the desired M2 so there should be a code that contains these formulas and they are related. gamma=1.4 and theta is around 30 degree, M1=3.1

[Dyuman Joshi]

1 - Run a while loop for the value of beta from 0.

2 - Define M2 using the formula given. Obtain theta from the tan relation.

3 - Update the value of beta in each iteration.

4 - When you reach the desired value of M2, break the value.

@Eda Deniz Soydinc: Please do not post multiple questions for the same problem.

@Eda Deniz Soydinc

If M1, gamma and theta are known, you can use the first equation to calculate beta. But you say you want to reach a given M2 by changing beta. You can't have both.

So again my question: what is given, what is unknown ?

Hi @Eda Deniz Soydinc

Can you at least put a little bit more of finger efforts in typing out the three equations using the following?

Then, we can probably help you to compute the oblique shock angles. By the way, since you didn't mention what oblique shock angles, it is very natural for me to assume that those associated with the trigonometric functions are the angles. Also, where should I put 3.1 (I mean the Mach number)?

tan()
theta
cot()
beta
M1
^2
sin()
cos()
gamma
()/()
p1
p2
M2
sqrt
