Description
Nan Li and others ran heat-shock crack tests in hot-rock stores in 2026, to learn how cracks meet natural joints. Hot-rock power needs crack work to widen heat-move space, but joint sets muddy the start of cracking. The team ran a lattice-spring model of crack-joint meets.
Fluid thickness, shock counts, meet angles, and joint sets were varied to map the boost effect. Square meet angles, mid shock counts, and thin fluids made the most heat-move space. The heat-shock spread zone spanned near one metre, where crack acts were mostly stop and push-through. Hot-rock engineers gain rules for crack plans that max heat trade.
