2. Mitigation of Pressure Pulsations in Axial turbine draft tube with jet injection or solid rod protrusion: A Numerical investigation
Abstract : The introduction of intermittent renewable energy sources, such as wind and solar power, to the power grid, demands some hydraulic turbines to operate at unfavorable operating conditions not initially designed for. Strong swirl develops at loads below the best efficiency point, (BEP) due to angle mismatch between the guide vanes and the fixed runner blades typical for Francis and Propeller turbines. READ MORE

3. Reliability and Life Cycle Cost Modelling of Mining Drilling Rigs
Abstract : In the context of mining, drilling is the process of making holes in the face and walls of underground mine rooms, to prepare those rooms for the subsequent operation, which is the charging process. Due to the nature of the task, drilling incurs a high number of drilling rig failures. READ MORE
