Anyoon Rotary engine

Posted January 11, 2010 at 11:42 by dijinj

I had invented a rotary engine with efficiency of more than 79%. The new rotary engine achieves this by implementing both constant volume heat addition, water injection for cooling and Atkinson Cycle. Implementation of constant volume heat addition is considered to be a holy grail in IC engine design and Constant volume heat addition can provide 50% more power and there by efficiency over existing engines (assuming efficiency of existing engines is 30%) while using same amount of fuel(Ref: ‘Design...

On many occasions, it is necessary to replace the grid while retaining all of the settings for the case. It can be tiresome to start by reading a new mesh file and then duplicating the case setup by specifying settings through the GUI . In addition, there is always a chance for making an error when specifying
