Turbulent mixing due to hydrodynamic instabilities occurs in a wide range ofscience and engineering applications such as supernova explosions and inertialconfinement fusion. The experimental, theoretical and numerical studies help usto understand the dynamics of hydrodynamically unstable interfaces betweenfluids in these important problems. In this paper, we present an increasinglyaccurate and robust front tracking method for the numerical simulations ofRichtmyer-Meshkov Instability (RMI) to estimate the growth rate. Thesingle-mode shock tube experiments of Collins and Jacobs 2002 for two incidentshock strengths ($M=1.11$ and $M=1.21$) are used to validate the RMIsimulations. The simulations based on the classical fifth order weightedessentially non-oscillatory (WENO) scheme of Jiang and Shu 1996 with Yang'sartificial compression are compared with Collins and Jacobs 2002 shock tubeexperiments. We investigate the resolution effects using front tracking withWENO schemes on the two-dimensional RMI of an air/SF$_6$ interface. We achievevery good agreement on the early time interface displacement and amplitudegrowth rate between simulations and experiments for Mach number $M=1.11$. A 4%discrepancy on early-time amplitude is observed between the fine gridsimulation and the $M=1.21$ experiments of Collins and Jacobs 2002.
