MH's ideal coil and voltage question

[MileHigh]

Brad:

You clearly make no attempt to seriously respond to the technical argument that I made that clearly shows that there is no resonance at all in operation on the exhaust side as shown in the link provided by AC.

Instead, you do a chicken dance and try throwing spaghetti against the wall and hoping some of it will stick.  It's just a lousy performance and I will deal with it in another posting.

But the saddest thing of all, is that you simply couldn't admit that the way the exhaust system works to optimize the performance of the engine is a timing-based function and not a resonance-based function.  It is absolutely clear to me that this is the case and I am quite certain that the majority of readers would agree.  Instead of just admitting to it like a man, you shrink away from it and try to hide behind fake lol's and smiley faces.  And I have seen countless examples of this before and I think that is sad.

Okay, now I am going to deal with your chicken dance.

One day it is,and the next it is not.lol.

Ha ha ha, big joke.  Here you are like a hawk plucking quotes of mine from way back in the discussion.  If you are such a hawk then you saw how several times that I expressed doubts that on the exhaust side that there was any form of true resonance in play.  The AC provided a good link and it confirmed my doubts as well as being informative and teaching me.

And all that you can do is dance like a funky chicken and try to do a "set up" to "prove" that I am contradicting myself.

And when that cycle time aligns perfectly with the cycle time of the pistons port position,we have what between the two that gives rise to a maximum amplitude of pressure in the combustion chamber?. When do you obtain resonance in an LC circuit?--when the cycle time is correct 

This is smiley-faced dancing chicken bullshit.  You are ignoring everything technical I said and falling flat on your face.

Quote: By one definition a Helmholtz resonator augments the amplitude of the vibratory motion of the enclosed air in a chamber by taking energy from sound waves passing in the surrounding air. In the other definition the sound waves are generated by a uniform stream of air flowing across the open top of an enclosed volume of air.

And this says absolutely nothing about pressure waves inside the Helmholtz resonator.  Rather, it discusses how sound waves external to the resonator can be picked up and amplified by the Helmholtz resonator.  It also discusses how a Helmholtz resonator can generate sound waves external to the resonator.  So more useless dancing chicken.  Plus I am pretty sure based on all of the discussions that we have had together that you didn't have slightest idea how a Helmholtz resonator actually worked until I explicitly told you how one worked.  See attached diagram.

By the way, the "K" is for the spring constant, and the symbol should obviously not be confused for a resistance, it's a symbol for a spring.  Note the "Rm" and the associated symbol is for the "resistor."  I put resistor in parenthesis because in fact an electrical resistor in the electrical circuit world is in reality modeled by a "damper" in the physical world.  It's like a car shock absorber without the spring.

And that is what you have done time after time.
The fact is,that it is the exhaust side that dose 90% of the work by way of a resonant system. I tried to tell you this earlier on in this discussion,but you just kept on dribbling away.
I also tried to tell you to go and learn a thing or two,before trying to work out how it all work's,but i can see it was left for others to do for you--no surprise there.

And this says absolutely nothing about pressure waves inside the Helmholtz resonator.  Rather, it discusses how sound waves external to the resonator can be picked up and amplified by the Helmholtz resonator.  It also discusses how a Helmholtz resonator can generate sound waves external to the resonator.  So more useless dancing chicken.    See attached diagram.

Helmholtz Resonance

A Helmholtz resonator or Helmholtz oscillator is a container of gas (usually air) with an open hole (or neck or port). A volume of air in and near the open hole vibrates because of the 'springiness' of the air inside.

Sound-- is a type of energy made by vibrations. When any object vibrates, it causes movement in the air particles.

Plus I am pretty sure based on all of the discussion that you didn't have slightest idea how a Helmholtz resonator worked until I explicitly told you how one worked.

MH,you are clueless as to what i know.
You think that no one here knows anything ,unless you tell them.
The fact that pressure waves do exist inside a Helmholtz resonator,just shows how little you know.

I have not seen anyone try and steer people in the wrong direction more than you do.
I only hope that there is not to many that take notice of your rubbish.

Brad:

Okay, moving on to the bitter end.

Quote: A tuning fork serves as a useful illustration of how a vibrating object can produce sound. The fork consists of a handle and two tines. When the tuning fork is hit with a rubber hammer, the tines begin to vibrate. The back and forth vibration of the tines produce disturbances of surrounding air molecules. As a tine stretches outward from its usual position, it compresses surrounding air molecules into a small region of space; this creates a high pressure region next to the tine. As the tine then moves inward from its usual position, air surrounding the tine expands; this produces a low pressure region next to the tine. The high pressure regions are known as compressions and the low pressure regions are known as rarefactions. As the tines continue to vibrate, an alternating pattern of high and low pressure regions are created. These regions are transported through the surrounding air, carrying the sound signal from one location to another.

More dancing chicken.  I state that the tune pipe generates a time delay inside the pipe based on a returning pressure wave echo.  So you do a dance and produce a quote about how a resonating tuning fork produces sound (pressure waves) in the external air around the tuning fork.  As we know, and as you yourself stated, a tuning fork producing sound in the air represents the draining of energy out of the tuning fork and putting it into the air.

What does a tuning fork producing sound in the external air have to do with a tune pipe and it's associated delayed pressure wave inside the pipe? NOTHING.

  Holly crap MH--they do the same thing-->the tuning fork and expansion chamber 
But one of them resonates,and the other dose not--you just have them mixed ass about.

Holy crap Mr. Chicken!  They don't do the same thing at all - it's a false equivalency!  Mr. Chicken is guilty of many false equivalencies.  Smiley faces will not fix that!

And of course, you have it ass about.  The tuning fork clearly resonates by exchanging kinetic and potential energy back and forth just like an LC resonator exchanges inductive and capacitive energy back and forth.  And the tune pipe/expansion chamber is clearly a time delay device and you haven't provided a single shred of evidence that it resonates.  Isn't that funny?

Yes, the "'springiness' of the air inside" is the SPRING in the Helmholtz container.  Pressure waves do not travel through the spring, rather, the spring is a spring.

Your citing of a definition for "sound" is meaningless.  You make no attempt whatsoever to put your own intellectual content in here.  You are just throwing two strings of spaghetti against the wall and adding zero added value and zero brainpower.  You are just making another false equivalency, and a ridiculous one at that.

MH,you are clueless as to what i know.

Since you demonstrated no knowledge about what resonance actually is, I can make a very strong inference that you had no clue whatsoever how a Helmholtz resonator actually works.

The fact that pressure waves do exist inside a Helmholtz resonator,just shows how little you know.

That's my cue for 10 smiley faces.  The model for a Helmholtz resonator is such that the volume inside the resonant cavity acts like a spring.  That means that the wavelength of sound associated with the resonant frequency is much larger than the dimensions of the cavity.  Therefore, it's impossible for any pressure waves to exist inside the cavity.  At any given time, the pressure in the cavity is only a "small portion of a sine wave" and therefore the pressure is more or less constant throughout the cavity as it cycles up and down.  Another thing that you just learned Brad!

I have not seen anyone try and steer people in the wrong direction more than you do.
I only hope that there is not to many that take notice of your rubbish.

The truth is that you have learned a hell of a lot of stuff from me on these two threads but your big brain fry won't let you say that so all that you can say is the hollow fake-ass "rubbish" line.
