Hello Paul,

enclosed there's a picture of a very special "coffee delivery machine" - I
hope, you already have one of this type at home ... ;-)

And now more seriously ...

I've found a little free CFD software, "Flowsquare" by Yuki Minamoto.
The 2 graphics are the result of a first "test". One figure shows the flame
kernels after ignition (both with the same timing), the other one
illustrates the maximum of the flame expansion, I've reached with this
configuration ...

Well, you know, my graphic abilities will tend to zero, so please excuse the
primitive look ... ;-)

Rotor position is ~ 15 deg aTC, the recess shall be a MDR type ...

Unfortunately I do not know / understand all the parameters + properties,
you have to look at in the configuration file ...

Of course, it's more like a joke - the chamber is fixed + we need moving
parts ... But the colors are looking nice + you can see, that the walls will
cool / extinct the flame ... ;-)


With kindest regards

Franky / Frank Herfert
