Silvio Barbarelli graduated in Mechanical Engineering at the University of Calabria. From 1997 to 1999 he attended the twelfth cycle Ph.D. in Machine Engineering at the University of Bari and holds the title of Doctor Research in March 2000. During this period, he has developed a research in the field of the hydraulic pumps used as turbines (PATs). He has carried out experimental activities, by measuring several pumps at test rig and developing numerical models for predicting the performances of an assigned PAT. During the post Ph.D. he has been involved in the set up of the electronic instrumentation of the compressible fluid small turbines test rig. Later (2007) he began to attend the second Ph.D. in Mechanical Engineering (22th cycle) at Mechanical Department of the University of Calabria (DIMEG), by working in the field of oil pumps. Then he holds for the second time the title of Doctor Research in March 2012. Now he is Temporary Research Fellow at DIMEG by conducting the following activities: - Design of an innovative hydrokinetic marine turbines; - Design of a new wave energy converter based on a point absorber and a hydraulic system; - Experimental and theoretical activities in the field of the pumps running as turbines; - Development of micro turbines useful to recover energy from compressible low enthalpy fluids - Development of micro wind turbines for home applications.
