Foil 38 Approximations used in derivation of Thin-Layer and Parabolized Navier-Stokes Equations

From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox
1 These are derived from full NS (Navier-Stokes) equations with a set of approximations.
  • Boundary Layer = "leading order 1/R1/2 "
  • Thin Layer and PNS are more accurate expansions in 1/R1/2
2 PNS drops ¶/¶(flow direction) viscous stress terms
3 TLNS drops these derivatives in both surface directions
