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...

Modern scleral lenses part II: patient satisfaction.

PURPOSE To evaluate the subjective performance of modern scleral lenses in patients of the clinics of Visser Contact Lens Practice. METHODS In this cross-sectional survey, all the necessary data were collected at the first follow-up visit during the 5-month study period. In accordance with the preformed fitting technique developed at Visser Contact Lens Practice, four types of scleral lenses ...

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 ...
