Rolling bearings in modern wind turbines operate under demanding tribological conditions that include high contact stresses, mixed lubrication, transient loads, electrical discharge, corrosion, and hydrogen-assisted damage. These factors contribute to premature failures such as micropitting, scuffing, white etching cra...
This article examines the key engineering challenges associated with the mechanical design of offshore wind turbines operating in harsh marine environments. The study discusses the main structural categories–foundations, towers, and rotors–emphasizing their suitability for different sea depths and geological conditions...

Exhaust valves in medium-speed marine diesel engines experience coupled combustion heating, intermittent seat cooling, repeated impact and microslip, deposit-assisted corrosion, and prolonged service. Their degradation therefore cannot be explained or qualified using a single room-temperature property. This review orga...

Hydropower valves operate under transient, high-pressure conditions in which local throttling, pressure recovery, vortex evolution, and pressure pulsation govern hydraulic performance, cavitation, erosion, and flow-induced vibration. This review synthesizes recent advances in numerical modeling of these coupled phenome...

Wind turbines are among the most widely adopted renewable energy systems, yet the end-of-life management of wind turbine blades remains a major challenge. The turbine blades are primarily made of glass fiber-reinforced polymers (GFRP), which are difficult to recycle without degrading their inherent structural integrity...
