OK, let's try a little "applied physics".
First, I like to race. Now that the season is over, it's time to use
the cold winter to find more horsepower. While browsing through my
large stack of science, engineering and physics books, I stopped with
a copy of Schaum's Outlines, "Fluid Dynamics, Second Edition".
Buried in the back of the book was a chapter titled "Compressible Flow -
MagnetoGasDynamic Channel Flow". Hmmm, that sure sounds like an intake
port to me! Started reading and fired up my copy of StudyWorks (a small
version of MathCAD) to see if I could get the equations to work out. The
theory behind MGD seems to indicate that I'm understanding what's going on,
at least a little.
Woe is me! I think that the explanation in the book is incomplete. At
least to my understanding. Here is what I would like to do. Compute how
fast the charge in the intake tract would move under how much of a
magnetic field. I need to see if I can get the flow to accelerate to about
.6 Mach at less than 4000 RPM and hold that figure up to about 6500 RPM.
I plotted my current intake speed and I'm about 21% Mach at 4000 RPM (my
current torque peak). At 3500 - 18%, 3000 - 15.5%, 2500 - 13%.
I also need to compute how much voltage I need to produce that magnetic
effect to achieve that .6 Mach.
I am very sure that at some time in the future, someone will come to visit
me and find a large crater where my garage used to reside. It will be the
result of either the failure of one of my "speed experiments" or the success
of my invention of a space/time warp!
P.S. I am not above jumping over to the Chemistry forum to see if there is
a chemical I add to the fuel to increase conductivity (which appears to be one
of the parameters of MGD). Naturally without decreasing the power produced by
the fuel. ;-))
Am I going in a wrong direction? If not, can some one help me?
P.P.S. I came across this site many years ago but this is the first opportunity I've had to use it so please be patient! ;-))))
