Combustion Characteristics of a Diesel-hydrogen Dual Fuel Engine

Among the alternative fuels, hydrogen shows great potential in the near future. In the present study, hydrogen utilization as diesel engine fuel was investigated. Hydrogen can not be used directly in a diesel engine due to its autoignition temperature higher than that of diesel fuel. One alternative method is to use hydrogen in enrichment or induction. To investigate the combustion characterist...

Optical Measurements for Ramjet Engine Development

INTRODUCTION Advanced propulsion systems involve highly complex combustion flow processes. Extensive and accurate flowfield measurements can help to guide and support engine development. For example, in the hypersonic dual-combustor ramjet, the subsonic combustion chamber operating at fuel-rich conditions generates a complex multiphase combustion flow comprising liquid fuel droplets, soot parti...

Grate Furnace Combustion: A Submodel for the Solid Fuel Layer

The reduction of NOx-formation in biomass fired grate furnaces requires the development of numerical models. To represent the variety in scales and physical processes playing a role in the conversion, newly developed submodels are required. Here, a submodel for the reverse combustion process in the solid fuel layer on the grate is described. The submodel is shown to give good predictions for th...
