abstract = {<p style="text-align: justify;">In low speed flow computations, compressible finite-volume solvers are
known to a) fail to converge in acceptable time and b) reach unphysical solutions.
These problems are known to be cured by A) preconditioning on the time-derivative
term, and B) control of numerical dissipation, respectively. There have been several
methods of A) and B) proposed separately. However, it is unclear which combination
is the most accurate, robust, and efficient for low speed flows. We carried out a
comparative study of several well-known or recently-developed low-dissipation Euler
fluxes coupled with a preconditioned LU-SGS (Lower-Upper Symmetric Gauss-Seidel)
implicit time integration scheme to compute steady flows. Through a series of numerical
experiments, accurate, efficient, and robust methods are suggested for low speed
flow computations.</p>},
