Numerical analysis of spray characterization of blends of hydrous ethanol with diesel and biodiesel.

The spray characteristics of a fuel greatly influence the combustion as it affects the formation of an air-fuel mixture, which directly impacts the performance and emissions of the engine. This study investigates the physical injection spray characteristics of biofuels to optimize the engine operating parameters for their effective utilization. For the analysis of the spray characteristics of pure diesel (D100), 80% diesel-20% biodiesel (D80B20), 80% diesel-10% biodiesel-10% pure ethanol (D80B10E10), and 80% diesel-10% biodiesel-10% hydrous ethanol (D80B10HE10) are investigated.

Biomechanical investigation of tasks concerning manual materials handling using response surface methodology.

In typical manual material handling, the variations in walking pattern are decided by various factors, such as load being handled, frequency of handling, walking surface, etc. Traditional gait analysis protocols commonly evaluate individual factor within specified ranges associated with particular activities or pathologies. However, existing literature underscores the concurrent impact of multiple factors on gait.

Influence of injection strategies on ignition patterns of RCCI combustion engine fuelled with hydrogen enriched natural gas.

The depletion of fossil fuel and the concerns for harmful emissions and global warming has instigated researchers to use alternative fuels. Hydrogen (H) and natural gas (NG) are attractive fuels for internal combustion engines. The dual-fuel combustion strategy is promising to reduce emissions with efficient engine operation.
