abstract = {<p style="text-align: justify;">A type of hybrid WCNS and CPR method for solving conservation laws on
hybrid structured and unstructured meshes is proposed. WCNS on structured grid
is conjoined with CPR on unstructured grid through CPR on structured grid. The
main hybrid technique becomes coupling WCNS and CPR on curvilinear structured
grid. Calculation of grid metrics, interpolation methods of physical coordinates and
state variables, and computation of Riemann flux near coupling interface are designed
to maintain the expected high order accuracy and to satisfy discrete geometric conservation
laws in the whole computational domain. Third-order schemes and fifth-order
schemes are considered. Numerical simulations show that the proposed hybrid
WCNS-CPR schemes can obtain designed accuracy, satisfy geometric conservation law
and have good balance of computational efficiency and grid flexibility.</p>},
