The champagne effect is a two-phase flow instability that could occur in a hydraulically compensated compressed-air energy storage (CAES) power plant. This report discusses the effect in detail and describes the development and calibration of the CHAMP model, a computer model that successfully simulates the dynamics of the water and air in the vertical underground shaft of a CAES hard-rock plant.
