I am sure everyone has seen Interstellar movie. In the movie, Cooper proposes to orbit around Gargantua, parallel to Miller's planet, to escape from the time dilation. One hour in Miller's planet is equal seven years in Earth's time. My question is, what would it look like, if we happen to view...
I am talking about the aerodynamic noise from the exhaust jets of an engine and not the mechanical noise. Any air flow causes noise take the example of wind. Likewise when a lava fountain comes out of the volcano mouth shouldn't it cause noise which can be heard from quite a distance like in the...
By other jets i am referring to jets issued from a nozzle for ex. jet engine jets. Considerable amount of noise is produced from the exhaust of jet engines. Why do lava fountains don't create that much noise when compared to the exhaust jets of jet engines?
If there was any possibility of reversing the direction of wing tip vortices, what would the effects be? Is there any chance of increasing the thrust or lift?
For example the right wing tip produces clockwise vortices and the left wing tip produces counter clockwise vortices(Aircraft viewed...
Why is a "potential core" region of a jet called a "potential core"?
We all know that there exists a region called "potential core" in a jet where there are no mean velocity gradients. My question is, why is it called a "potential" core?
I have completed my undergraduation in aerospace engineering. Inspite of studying all subjects there is one basic question which is left unanswered for me..Why do shocks form? Can anyone answer it please?
Both Fourier transform and z transform can convert discrete time domain to frequency spectrum domain. Then why do we use Fourier transform rather than z transform? What is the reason behind it? Both give us the frequency spectrum we want.
