Abstract
A Mach 1.55 shock and subsequent reshock interacting with predominantly single-mode and multi-mode interfaces between nitrogen and carbon dioxide is studied through three-dimensional adaptive mesh refinement simulations using the FLASH code. The simulations are directly compared with the PLIF/PIV experimental measurements to validate the computational code. Development of instability after first shock and chaotic turbulent mixing after reshock are discussed for the entire shock tube domain.
