Hydro Crack !link! Hot - Flow 3d

In industries like metal casting, welding, nuclear reactor cooling, or geothermal systems, high-temperature fluids interact with solid structures. “Hot cracking” (solidification cracking) occurs during the final stage of solidification when insufficient liquid feed meets thermal contraction stresses. FLOW-3D HYDRO, while primarily known for free-surface flows, can be extended to simulate conditions leading to thermal cracking.

| Indicator | Meaning | Action | |-----------|---------|--------| | > yield at BTR | Plastic strain localization | Reduce cooling rate | | Tensile principal stress + high H | Hydrogen-assisted cracking | Pre-heat/dry material | | Temperature gradient > 100°C/mm | Severe thermal shock | Change heat input pattern | | H concentration > 5 ppm (for steel) | High cracking risk | Use low-hydrogen process | flow 3d hydro crack hot
