A major component of aircraft noise is the jet noise created by the high velocity hot stream exhausting from a jet engine, interacting with itself and with the surrounding cold air. In the present paper the flow and acoustic fields that are generated by two coaxial jets are considered. Numerically, the problem is divided into a flow related part (Navier-Stokes system of equation) and an acoustic p
Clean technology has become a key feature due to increasing environmental concerns. Swirling flows, being directly associated with combustion performance and hence minimized pollutant formation, are encountered in most propulsion and power-generation combustion devices. In this study, the development process of the conceptual swirl burner developed at the Swedish National Centre for Combustion and
A persistent controversy in language evolution research has been whether language emerged in the gestural-visual or in the vocal-auditory modality. A "dialectic" solution to this age-old debate has now been gaining ground: language was fully multimodal from the start, and remains so to this day. In this paper, we show this solution to be too simplistic and outline a more specific theoretical propo
In line with the United Nation Sustainable Development goal #7 (clean and affordable energy), new carbon-neutral fuels need to be investigated. Methanol is a promising alternative e-fuel to fossil fuels for the application in gas turbines. The paper presents a numerical study of the efficient use of green methanol using in a wet Brayton cycle with chemical recuperation. The 1D flame analysis shows
Denna uppsatts behandlar ämnet finansskatter. Genom att studera olika finansskatter, för att sedan analysera och jämföra dem, så återges ett antal olika skatter, och fördelar och nackdelar med de olika skattemodellerna lyfts fram. De skatter som har studerats är finansiell aktivitetsskatt, löneskatt, kapitalskatt och transaktionsskatt. Vid en analys så framstår aktivitetsskatt och löneskatt som gThis thesis treats the subject of financial taxes. By the study of different financial taxes, and the analysis and the comparison of them, this paper is giving example of a range of financial taxes and presenting some of the benefits and disadvantages of each tax. The taxes included are: capital tax, financial activities tax, financial transfer tax, and salaries tax. When analysed, the financial
