Recently some studies have been carried out on RCCI (reactivity controlled compression ignition) engines; however, they routinely used the “one factor at a time” approach, which may neglect interactions among the manipulated factors. This paper reports the use of a more effective approach...

A multi-dimensional computational fluid dynamics (CFD) modeling was conducted on a D.I. (Direct Injection) diesel engine fueled by bio-diesel based on KIVA4 code. Comprehensive chemistry prediction of bio-diesel fuel was taken into account by enhancing the combustion model of the default KIVA4...

A numerical modeling study was performed to investigate the impacts of biodiesel blend ratio on the emission formation processes of a diesel engine. Simulations were conducted using 3-D CFD simulation software KIVA4 coupled with CHEMKIN II. The integrated chemical kinetics with 69 species and...

This article theoretically and empirically investigates the risk amplification effects of asset securitization among financial institutions in the USA based on a risk model and a single-factor time series model. Results show that systemic risk of financial institutions is enlarged by asset...

In the present study, effects of hydrogen induction on combustion characteristics of a compression ignition diesel engine were investigated and a comprehensive model for identifying knocking combustion was developed. This was done by defining number of critical local regions within the CFD...

Micro thermophotovoltaic (TPV) power generator is recognized as a promising portable power source for those applications where high power density and lightweight power source is the key of success. As one of the most important components of micro-TPV system, it is essential that the micro...

A multi-dimensional computational fluid dynamics (CFD) modeling was conducted on a direct injection turbo-charged diesel engine based on KIVA-4 code under full and mid engine loads. Multi-component fuel evaporation model of KIVA-4 was used and coupled with advanced combustion chemistry to...

Corporate bond prices are known to be influenced by default and term structure risk in addition to non-default risks such as illiquidity. Putable corporate bonds allow investors to sell their holdings back to the issuer and may thus provide insurance against all of these risks. We first document...
