Hello Paul,

perhaps the following Web address is what you're looking for:
www.food4rhino.com/app/rhinocfd

Btw, can you "create" animations of moving parts in Rhino or is the software
for construction only ?

Production cost ...
If you want to use high pressure / power + you will provide a long life of
an engine, then you should use sleeve bearings + oil cooled rotors. But
there are other markets, where the price ticket may "dictate" the kind of
production. In 1973 Yanmar has had compared the CCR + the OCR - they have
built both types - + they have found, that the cost for the OCR RE will be ~
30% higher ...
I think, even today there will be a similar difference in cost ... ?

Related to the AIE RE rotor cooling: they use a patent by David Garside. If
I have understand it the right way, it's a closed pressurized system using
the blowby gases ... (patent is enclosed).

With the kindest regards

Franky / Frank Herfert

Looks like it has centrifugal blower to me. Hence HP consumption.
Higher BSFC.

If an oil cooler and pump are 30% of the engine cost the engine it self much be
really cheap :-) You can get oil cooler's all day long for under $200.
