A Review of the Physics of Aircraft Trailing Vortices
Sørli, Karstein (Research report, 2015)In this review the formation, movement and persistence of aircraft trailing vortices are discussed. The focus is on parameters that are important for the safety and productivity of air travel and transport. This ... -
Analysis of Turbulent Wakes Behind Helicopter Hangars at Sola Airport
Sørli, Karstein; Tabib, Mandar; Rasheed, Adil (SINTEF Rapport;, Research report, 2015)Turbulence in the wake generated by airflow over buildings may produce complex airflow patterns in the downwind region. Examples include the recirculating flow and wind deficit areas behind airport buildings and their ... -
Assimilering av lokale data for beregning av tidsvarierende randbetingelser for turbulensvarsling ved flyplasser - tester på aktuelle flymålinger over Værnes
Sørli, Karstein; Utnes, Torbjørn (Research report, 2008)Vi har i en tidligere rapport (2008-07-02) beskrevet og testet en metode for estimering av dynamiske randbetingelser anvendt til lokal varsling av vindforhold nær flyplasser. Disse randbetingelsene antas å være viktige hva ... -
GRIDDLER and VISTA with CGNS interface
Sørli, Karstein; Holdahl, Runar (Research report, 2006)This developer's and user's note has been written to help developers and users of GRIDDLER and VISTA to maintain and use their recent CGNS (CFD General Notation System) interface. The present note contains a description ... -
Impact Assessment of Adverse Turbulence due to Landscape changes close to Airports. Mathematical and Software Tools for Terrain Modification and Impact Assessment
Sørli, Karstein; Rasheed, Adil (SINTEF Rapport;, Research report, 2013)In places dominated by irregular terrain, significant topographical modifications are often required to develop new or improve the existing infrastructure like roads, buildings, airport terminals and harbours. If the ... -
Lokal data-assimilering i SIMRA: Korreksjon av vindstyrke og retning ved bruk av flydata
Utnes, Torbjørn; Sørli, Karstein (Research report, 2009)I denne rapporten er det gjennomført systematiske korreksjoner av SIMRA-prediksjoner ved bruk av flydata. Disse korreksjonene er gjort på grunnlag av sammenligninger mellom ukorrigerte simuleringer og flydata i øvre del ... -
