In this paper, we present an unsplit method for the time-dependent
  compressible Navier-Stokes equations in two and three dimensions.
  We use a a conservative, second-order Godunov algorithm.
  We use a Cartesian grid, embedded boundary method to resolve complex
  boundaries.  We solve for viscous and conductive terms with a
  second-order semi-implicit algorithm.  We demonstrate second-order
  accuracy in solutions of smooth problems in smooth geometries and
  demonstrate robust behavior for strongly discontinuous initial
  conditions in complex geometries.

We present a second-order accurate projection method to solve the
  incompressible Navier-Stokes equations on irregular domains in two
  and three dimensions.  We use a finite-volume discretization
  obtained from intersecting the irregular domain boundary with a
  Cartesian grid.  We address the small-cell stability problem
  associated with such methods by hybridizing a conservative
  discretization of the advective terms with a stable, nonconservative
  discretization at irregular control volumes, and redistributing the
  difference to nearby cells.  Our projection is based upon a
  finite-volume discretization of Poisson's equation.  We use a
  second-order, $L^\infty$-stable algorithm to advance in time.  Block
  structured local refinement is applied in space.  The resulting
  method is second-order accurate in $L^1$ for smooth problems.  We
  demonstrate the method on benchmark problems for flow past a
  cylinder in 2D and a sphere in 3D as well as flows in 3D geometries
  obtained from image data.
