Diesel engine development in view of reduced emission standards

Knecht, Walter - In: Energy 33 (2008) 2, pp. 264-271

Diesel engine development for use in light-, medium- and heavy-duty road vehicles is mainly driven by more and more stringent emission standards. Apart from air quality related emissions such as nitrogen oxides and particulates, also greenhouse gas (GHG) emissions are likely to become of more...

Field Application of the Multilinear Muskingum Discharge Routing Method

Sahoo, Bhabagrahi - In: Water Resources Management 27 (2013) 5, pp. 1193-1205

To implicitly model the nonlinear dynamics of flood wave propagation in rivers with floodplains, a multilinear discharge-hydrograph routing method based on time distribution scheme is proposed. The framework of this method is based on the variable parameter Muskingum-type routing method, which...

Numerical solutions of unsteady flows with low inlet Mach numbers

Punčochářová-Pořízková, Petra; Fürst, Jiří; … - In: Mathematics and Computers in Simulation (MATCOM) 80 (2010) 8, pp. 1795-1805

This study deals with a numerical solution of a 2D unsteady flow of a compressible viscous fluid in a channel for low inlet airflow velocity. The unsteadiness of the flow is caused by a prescribed periodic motion of a part of the channel wall with large amplitudes, nearly closing the channel...
