The aim of this study was to ecologically analyze the flow field and fluid pressure on the interlayer in the construction of salt-cavern gas storage in terms of terrestrial ecology. With the help of CFD software Fluent, the cavity numerical models in different working environments had been built and the influence of water injection rate, height of the central tube and inter-medium tube, height and length of interlayer had been analyzed. The results show that the existence of interlayer breaks up the continuity of cavity boundary and causes many...
