I have modified my rice engine to create sound. Also, I have studied a bit about sound resonators and learned that a pipe that is closed on one side and open on another side is named a quarter-wave resonator and the frequency of resonance is very well known. I made the length of the rice engine variable using small cans that I have collected (I use to keep the cans when I finish eating their content to be able to do experiments such as this). using a mobile phone it was easy to analyze the sound frequency and magnitude. the experiment clearly showed that the formula for calculation of resonance frequency worked very well. very loud sound can be produced this way, I went up only to 105 dB to avoid bothering my neighbors.

wow thats so cool. I was thinking that you don't even need to make it that tall tho. if you learn to play with the concept of cavity ressonance in relation to the speed in which the sound pressure wave exits the cavity via the exit point you can manipulate the frequency to your desired FR hrtz rate. You can manipulate the ressonance frequency by playing with the exit opening, by making it narrower and even putting lids on top you can modulate the speed in which air pressure wave escapes out which then controls the frequency range. would like to see more of this experiments,
Hello, how did you know that your thermoacoustic engine works based on a quarter wavelength? Why doesn't it work based on half wavelength? Thank you
Cool! I am curious, if the rice is changed to anther kind of beans, what will happen? It will be the same?

I have changed rice with wheat and it works almost the same way. I think many things will work, but I need to figure out what the properties should be. I will make a complementary video for that.

@@HVE Nice! Looking forward to your video!
Thank you for your good work. Can you please make a tutorial video about parallel capacitor with AC signal input in COMSOL?

@@muhammedkara9185 Electric field does not change with frequency for an ideal capacitor. It follows the AC voltage that you apply between the terminals, so it changes, but that change is obvious. What is the original question ?
