Simulation study on enhanced heat transfer of annular inner rib tube in geothermal coaxial heat transfer wellbore by Longfei Dong, Yanping Xin, Xiao Wu, Rui Zhang

“…The comprehensive performance evaluation factor (η) reveals that while the fan-shaped inner ribbed tube performs optimally at a rib height of 12 mm, η declines linearly with increasing rib width. Therefore, it can be concluded that while rectangular internally ribbed tubes are suitable for applications requiring high levels of heat transfer efficiency, fan-shaped internally ribbed tubes are more appropriate for scenarios demanding superior overall performance.…”

Solvable entanglement dynamics in quantum circuits with generalized space-time duality by Chuan Liu, Wen Wei Ho

“…We identify a broad class of initial product states wherein the effect of the environment on a small subsystem can be exactly represented by influence matrices with simple Markovian structures, resulting in the subsystem's full dynamics being efficiently computable. We further find additional conditions under which the dynamics of entanglement can be solved for all times, yielding rich phenomenology ranging from linear growth at half the maximal speed allowed by locality, followed by saturation to maximum entropy (i.e., thermalization to infinite temperature), to entanglement growth with saturation to extensive but submaximal entropy. …”
