| Abstract |
This work investigates experimentally and numerically the performance of the ALBA LINAC cooling system. The main objective is to enhance the hydraulic system in order to significantly improve its thermal and water flow stability. In normal operation some problems have been identified that affect the performance of the LINAC: flowrate below the nominal values and water flow decreasing in time. The cooling subsystems have been experimentally characterized in terms of the pressure drop and flowrate. The measurements were taken using a portable hydraulic unit made at ALBA as well as a set of ultrasonic flowmeters. For the numerical studies the cooling network has been simulated using the software Pipe Flow Expert. The experimental results have shown that a number of components are too restrictive. In some cases the possibility to increase the flowrate is limited. The numerical results show that the velocity magnitude is inadequate in some places, producing air bubble entrapment, high pressure drop at pipes and insufficient flow. Based on this study several modifications are presented in order to raise the nominal flow and to adequate the water flow velocities between 0.5 and 3 m/s.
