The physics of flow around straight and curved cylinders in tandem is investigated by means of direct numerical simulations (DNS), for transitional and turbulent flow regimes. For straight tandem cylinders in the reattachment regime, the effect on the gap and wake flow of transition to turbulence in...
Grain refinement of the parent austenite led to a significant change in the intervariant boundary network of martensite, ultimately improving the mechanical properties (i.e., toughness and hardness). Molecular dynamics simulation demonstrated that the propensity for crack propagation was largely...
In medical ultrasound, aberration is a phenomenon that causes distortion of the ultrasound wavefront as it travels through an inhomogeneous medium. Aberration has been investigated since the 1960s and is known as a major cause of image quality loss in several applications, such as abdominal, breast...
Barriers and good practices in ambitious projects How can we ensure good processes before, during and after the realization of a zero-emission area? How can we ensure that buildings are realized as intended? Why do we struggle with good intentions being lost in the process from early planning to...
Numerical weather prediction products, radar products, and user terminal observations are used to estimate propagation conditions for the nearest hours lead time. Validation results show good correspondence between predictions and observations using beacon data and user terminal data, but with an...
Dette er en sammendragsrapport av resultatene fra forskningsprosjektet "Nye miljørestriksjoner – konsekvenser for kraftsystemet". Prosjektet hadde som mål å gi en grundig forståelse av effektene av nye miljørestriksjoner for vannkraft på kraftsystemet. Tre kraftsystemmodeller, FanSi, Primod og EMPS...
Process intensification by cavitation is gaining widespread attention due to the benefits that the intense bubble collapse conditions can provide, yet, several knowledge gaps exist in the modelling of such systems. This work studies the numerical prediction of single bubble dynamics and the various...
