An experimental study of mixing induced by Rayleigh–Taylor (RT) instability at an Atwood number ( A t ) ~7.5 × 10 −4 and Schmidt number (Sc) ~1,000 has been performed. A new transient experimental facility developed on the working principles of the draw-tank facility at Cambridge (Dalziel et al. in...
