碩士 === 國立臺灣大學 === 機械工程學系 === 85 === This research paper mainly discussed on pressure dropcaused from oscillating flow through three interval cylinders which are postside-by-side to channel center byy experiment. The pressure drop ismeasured by joing the tubes outside the several holes digged on theperface of up-plate and cylinder.Then,use the camera to shoot the variation of water height in the tube.in addition,use the curve fittingto get a relation function,and use the conservation of momentum principleto get a 2-order nonlinear ordinary differential equation to transferwater height to variation of pressure drop.Finally,analyze and find outthe tendencyy of pressure drop in the channel and around cylinders.
