Dynamic pressure modeling of damper system for fluctuation flow

Modeling and simulation of pressurized tank is necessary to explore the dynamic characteristics. The knowledge of dynamic characteristics of discharging the pressurized tank is useful for investigating the damper performance of fluctuation flow phenomena. Some researchers have studied the dynamic characteristic of dynamic pressure on tank in very diverse level of complexity. In this work, a model of nonlinear pressurized tank was developed by some mechanical laws and some assumptions. We approach the dynamic characteristics of the nonlinear pressurized tank with an order one system. We found that the cut off frequency of damper depends on volume of damper tank flow capacity of restriction element.
