Hi Paul,

enclosed is the most actual example, generated by AVL CFD software. The
angles are related to the rotor, for ecc shaft degrees simply multiply with
3.

Shows a complete course of process.

Taken from a thesis written in German.

Of course, other engines - other pressure distribution. Depends on ignition
timing, position of spark plugs, shape of the recess, properties of fuel etc
etc ;-)

mobil phone / smartphone ...
If you need e-mail only during your visit + you know, how to get / send per
internet, a telephone card would not be necessary, is this correct ?

+ if you have your own phone, can I give the borrowed one back to the owner
?

Best regards

Franky


I have 2 phones. One is a relatively simple one and the second is a so called smart
phone. The question is will they work in Europe? They are both serviced by AT&T.

I will go to the AT&T office and ask.

Very pretty pictures.

What is Anhang F Druckfeld in Brennkammer ?

You know what they say about CFD.

Just send me the paper if you have it and you don't mind.

The data is very interesting. Apparently it is an artificial situation
where they start with atmospheric presser in the squish flow area and
then measure the pressure along the face of the rotor.

The real pressure at that point would be ten times that due
to the mechanical compression ratio or 150 psi. I am sure that
would increase the instantaneous velocity of the squish flow.

Never the less a very interesting paper.
I would love to see it translated to English.
