Presented at the STAR Global Conference 2012
Presented at the STAR Global Conference 2012 One of the major reasons for lower efficiency and higher unburned hydrocarbon and carbon monoxide emission for two stroke engine is short circuit losses that occur during the scavenging process. An attempt has been made in this study to understand and improve this phenomenon. A three dimensional transient CFD model is developed for a schnullar type 70 cc two stroke engine. The engine is installed in a small moped used for personal transport and load carrying. Three major processes, namely blow down (expansion), scavenging and compression have been...

The implementation of the revolutionary harmonic balance method for the solution of periodically repeating turbulent flows enables the study of unsteady effects in rotating machinery with computational time scales that are drastically reduced compared to traditional transient methodologies.
More than any other, the oil and gas industry is dominated by fluids. From the extraction, processing and delivery of the hydrocarbons, to designing offshore platforms that are more able to resist the most extreme environmental conditions, understanding the behavior of fluids in and around your process is critical to success in the intensely competitive oil and gas industry.
