  27 Description
  28     Transient solver for buoyant, turbulent flow of incompressible fluids
  29
  30     Uses the Boussinesq approximation:
  31     \f[
  32         rho_{k} = 1 - beta(T - T_{ref})
  33     \f]
  34
  35     where:
  36         \f$ rho_{k} \f$ = the effective (driving) kinematic density
  37         beta = thermal expansion coefficient [1/K]
  38         T = temperature [K]
  39         \f$ T_{ref} \f$ = reference temperature [K]
  40
  41     Valid when:
  42     \f[
  43         rho_{k} << 1
  44     \f]
