Lattice structures based on Triply Periodic Minimal Surfaces (TPMS) have been extensively studied in the field of heat exchange due to advantages they can offer terms increased area and enhanced convective phenomena, thanks their intricate geometry. Numerous studies conducted fluid motion within these structures, confirming that Computational Fluid Dynamics (CFD) simulations accurately replicate thermo-fluid dynamic behavior. However, such are computationally expensive may be difficult...
Abstract Additive manufacturing (AM) is one of the processes with most potential for producing components used in internal combustion engines and features high efficiency due to possibility building very complex shapes. Several drawbacks parts produced using AM are still unresolved, like poor surface quality, presence defects anisotropic mechanical behaviour, which all contribute decreasing fatigue strength compared material conventional processes. The effect direction on both macroscopic...
High temperature assessment of crack like defects in power plant components is one the most important task to ensure high energy conversion efficiency. Creep fatigue growth tests for P91 steel, conducted at 600°C on standard C(T) specimens with 0·1, 1 and 10 h hold times, are presented. Microscopic features creep damage were observed along path, polished etched cross sections tested specimens. The dominant mechanism formation microvoids microcracks associated tip, due effect during time. In...
Abstract Rotor discs for gas turbines are heavy components usually designed following a safe‐life approach, where the low‐cycle fatigue design is based on life curves with suitable probabilistic margins. However, in such component, there possible occurrence of undetected defects that can propagate at each startup–shutdown cycle, and therefore, defect acceptance criteria have to be defined different rotor regions (considering stress distribution temperature). Moreover, failure risk should...
