It was known that a mesh screen placed across an airflow will have an evening effect, distributing both the velocity and pressure across the screen, however this effect had not been quantified and the effect of different mesh geometries was unknown. It was desired to understand the relationship between airflow velocity, the pressure behind the screen and the free hole area of the screen. It was...

ABSTRACT The detection of gravitational waves has opened a new era for astronomy, allowing the combined use wave and electromagnetic emissions to directly probe physics compact objects, still poorly understood. So far, theoretical modelling these sources mainly relied on standard numerical techniques as grid-based methods or smoothed particle hydrodynamics, with only few recent attempts at usin...
