The problem was derived from a simple process in solar water heating system. In a new designed electric less split system we involved a kind of bubble pump. The main structure of bubble pump was design depend on the character of two phase flow. Beside experiment analysis, numerical simulation of this pumping action in the core tube of bubble pump is very important. In this paper we investigated the motion of bubbles in vertical tube in two dimensions. The testing experiment has been taken on the existed vacuum tube on the efficiency, temperature, pressure and circulates power. The heat and mass transfer was simulated. The result of numerical simulation gave worthful help of optimize design of bubble pump. The optimal dimension design of core tube inside of bubble pump is presented.
