The European Union's responses to the COVID-19 crisis: How to fight a pandemic with the internal market
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-26)In a liberalized market economy, states tend to purchase supplies required for producing publicly funded services, such as healthcare, from the markets instead of producing them themselves. The availability of critical supplies thus becomes a question of supply-side availability and supply chain management, and therefore their availability is conceptualized in terms of security of supply. The European ... -
New insight into air/spray boundary interaction for diesel and biodiesel fuels under different fuel temperatures
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-09)The liquid fuel breakup mechanism in spray injection with ambient air for diesel and biodiesel at different fuel temperatures is studied numerically. We find that biodiesel fuel type injection with low fuel temperature induces more air entrainment volume to the boundary of the spray than diesel fuel injection and higher fuel temperature.
