  • Involved Two Steps Comprising A Viscous Incompressible Flow Part And An Inviscid Acoustic Part
  • On Collocated Grids The Inviscid Solution Is Found To Be Mesh Dependent Due To Unavoidable Extrapola
  • Differing From The Case On Staggered Grid Where No Extrapolation Is Needed
  • The Situation Is Most Pronounced When A Sharp Body Is Considered
