A Static Model of a Geyser Induced by Gas Inflow

I derived a static model and a dynamical model of a geyser induced by gas inflow based on detailed observation of the indoor model experiments and have modified the dynamical model in diverse ways. In this paper we introduce the static model and analytical results of it for the sake of understanding of the spouting period of a geyser induced by gas inflow. I confirmed that results of analysis of the model agreed those of the indoor model experiments. As a result, dependence of the spouting period of a geyser induced by gas inflow on various parameters is clarified theoretically.
