abstract = {<p style="text-align: justify;">In this paper, a remapping-free adaptive GRP method for one dimensional
(1-D) compressible flows is developed. Based on the framework of finite volume
method, the 1-D Euler equations are discretized on moving volumes and the resulting
numerical fluxes are computed directly by the GRP method. Thus the remapping
process in the earlier adaptive GRP algorithm [17,18] is omitted. By adopting a flexible
moving mesh strategy, this method could be applied for multi-fluid problems. The interface
of two fluids will be kept at the node of computational grids and the GRP solver
is extended at the material interfaces of multi-fluid flows accordingly. Some typical numerical
tests show competitive performances of the new method, especially for contact
discontinuities of one fluid cases and the material interface tracking of multi-fluid
cases.</p>},
