The “Rotary” Steam Engine

Apex Seals for a MEMS Rotary Engine

This paper presents possible solutions to the problem of leakage in the MEMS rotary engine currently being developed at U.C. Berkeley. The project is motivated by the challenge to develop a system capable of a higher specific energy than primary batteries. Currently, leakage is the limiting factor in obtaining an engine with an acceptable efficiency. Fluidic analysis has been done to determine ...

Britain Sabotaged the Steam Engine of Leibniz and Papin

The early history of the invention of the steam engine shows without doubt that the British Royal Society, including Isaac Newton personally, deliberately prevented the industrial and naval applications of steam power for nearly 1 00 years. In fact, the Royal Society was so intent on burying Denis Papin's 1690 invention of a paddle-wheel-driven steamship, worked out in collaboration with Gottfr...

Numerical Analysis on Combustion Characteristic of Leaf Spring Rotary Engine

The purpose of this paper is to investigate combustion characteristics for rotary engine via numerical studies. A 3D numerical model was developed to study the influence of several operative parameters on combustion characteristics. A novel rotary engine called, “Leaf Spring Rotary Engine”, was used to illustrate the structure and principle of the engine. The aims are to (1) improve the underst...
