Investigation of Flow Characteristic on Ram Pump in Different of Pipe Junction Geometry

Abstract

Ram Pump is a mechanical device that uses phenomenon of difference pressure to distribute the water toward high state level. The advantages of ram pump are low cost, construction of reliable and without electrical energy. Kinetic and potential energy are main factor to flow the water in driver pipe. This research purposed to determine flow characteristic in different geometries of ram pump based on experiment data. Ram pump operated on different pressure of inlet area which was get from water level. To get the flow characteristic of rum pump, it was simulated using computational fluid dynamic. The result of simulation was found that junction type of U shape appeared wake in driver pipe area; thus, this phenomenon indicated any turbulent flow because decreasing of pressure. In other junction pipe, wake phenomenon appeared in driver and delivery pipe area.
