KW - Finite volume methods, well-balancing, compressible Euler equations with gravity.
AB - <p style="text-align: justify;">We develop a second order well-balanced finite volume scheme for compressible Euler equations with a gravitational source term. The well-balanced property
holds for arbitrary hydrostatic solutions of the corresponding Euler equations without
any restriction on the equation of state. The hydrostatic solution must be known a
priori either as an analytical formula or as a discrete solution at the grid points. The
scheme can be applied to curvilinear meshes and in combination with any consistent numerical flux function and time stepping routines. These properties are demonstrated on a range of numerical tests.</p>
