Oscillating Engine Simulator
- 4gotunameagain 3y agoThis is very cool. I'm afraid the only way to get a more accurate answer about the inlet/outlet ports airflow is nothing short of CFD. This is because apart from the inlet geometry, the current geometry of the cylinder and the position of the valve also play a role. A jet that enters the cylinder at an angle is more likely to "fill" it faster and "see" less resistance in the inlet part, due to a vortex created within the cylinder. The model can be evaluated in e.g. 10 different positions of valve overlap for a given geometry, and the missing points interpolated. Very fun project !
- blkhawk 3y agoI actually have a commercial version of an engine like that :) A wilesco D2 - https://www.wilesco.de/en/steam-engines/stationary-steam-engines https://www.wilesco.de/en/steam-engines/stationary-steam-eng... Its mostly a deskoration. I took it apart and it has the sliding block design as described in the link.
