Study on impacts on resource efficiency of future EU demand for bioenergy (ReceBio). Final report

This project was commissioned to examine the resource efficiency implications of increased EU use of bioenergy for electricity and heat until 2050. Methods of analysis include an extensive literature and statistical review, detailed GLOBIOM modelling of cross-sectorial wood biomass production and use, and in-depth analysis of the implications on a multitude of sustainability indicators. The results for biomass use for material and energy are reported for EU28, while the sustainability indicators are assessed both for the EU and globally. In addition, country specific assessments were carried out for three case countries (Finland, Germany, and Italy) to examine the results against country-specific policies and resource

Influence of Intake Orientation on Ramjet Performance

The dependency of the performance of a two-dimensional intake for air-breathing missiles on intake orientation has been investigated experimentally. The main objective of the study is to identify the ideal intake position on the missile body. Experiments have therefore been carried out at combinations of different angles of attack and different roll angles of the intake and the missile body. All tests were performed at the intake design Mach number of 2.5 and at angles of attack ranging from 0 to 30 in the Trisonic Wind Tunnel Cologne. The results show that the ideal intake position depends on boundary-layer flow, flow separation, and vortices, which vary with different angles of attack. Furthermore, some intake orientations show a mass flow rise on the windward side, where the intake could be located
