Abstract

We modified further our extended dynamic model of a geyser induced by an inflow of gas, by taking into consideration the effects during spouting of an elbow shape, pairs of sudden expansions and contractions, and repeats of this shape in an underground watercourse. Through numerical simulations of this extended dynamic model, we see that a large number of sudden expansions and contractions or a large angular elbow in the underground watercourse greatly affects the spouting dynamics of the geyser.
