Background and activities
1. About
I have obtained Ph. D. in Mechanical Engineering, specialized field – Hydropower, and the total 20 years of experience in industry, research and academic teaching. My work focuses on fundamental and applied research of turbines and pumps that includes laboratory measurements, computational fluid dynamic analysis and fluid structure interactions. The current research focuses on investigation of fatigue damage to the Francis turbines, which are subject to variable blade loading due to intermittency and energy flexibility. My research group aims to develop the next-generation of hydropower technology with robust turbine design and operational flexibility.
