Upper part-load instability in a reduced-scale Francis turbine: an experimental study

François Avellan, Elena Vagnoni, Andres Müller, Ali Amini

Francis turbines with medium or high specific speeds may experience a particular type of instability in the upper part load in which the precessing vortex has an elliptical shape. The occurrence of the upper part-load instability (UPLI) is accompanied by l ...

Abundant nitrogen oxide and weakly acidic environment synergistically promote daytime particulate nitrate pollution

Athanasios Nenes

Nitrate is formed through the chemical production of gas-phase nitric acid and subsequent partitioning to the aerosol phase during the daytime. Many studies in the past separated these two aspects, even though they occur simultaneously in the atmosphere. T ...
