Some example of tasks solved in Energy Conversion Department.

Researches are based on our in-house code D-KRAT based on the algebraic 0D model of mass, momentum and energy balances extended by additional evolution equations for the following physico-chemical phenomena:

• Thermal deformations
• Cyclic plasticity and reattaching
• High temperature creep
• Stress/thermal induced phase transitions
• Hydrogen, oxygen and carbon generated chemical reaction/diffusion
• High temperature stress corrosion
• Low cyclic corrosion
• Electrochemical corrosion
• Hydrogen ductility
• Environmental interaction with surrounding fluid via electrochemical potential and pH
• Low cyclic fatigue
• Low cyclic damage evolution as a synenergic effect of chemical reaction products, mechanical and thermal loading during a real exploitation cycle.

D-KRAT code is especially dedicated for on line numerical simulation of the referential state of structures in real exploitation cycle, which consist four main elements:

• start-up
• nominal work
• shut-down
• stay
