Foil 12 What is relation of NAS benchmarks to Navier Stokes Equations -- Terms T V W ?

From Introduction to Physics and Numerics of NAS Benchmarks CPSP713 Case studies in Computational Science -- Spring Semester 1996. by Geoffrey C. Fox


1 The terms T (U,Ux) V(U,Uh) and W(U,Uz) include
  • A numerical viscosity term proportional to d(1..5)x,h,z which ends up if all the values of d are equal (which they almost are) as a equation like:
  • An approximation to Viscosity term in Navier Stokes Equation where ALL cross derivatives as listed below, are neglected
    • This approximation is implied by equation (3.1a) which doesn't allow such terms as those above.
    • Note also that numerical coefficient (k3 . k4) seems to be missing in 5th component of T U and W
  • The Ñ Temperature term for evolution of r E ( 5th componentof U)
