J. Cent. South Univ. (2017) 24: 506-514 DOI: 10.1007/s11771-017-3453-5 Simulation of isothermal precision extrusion of NiTi shape memory alloy pipe coupling by combining finite element method... extruded NiTi shape memory alloy (SMA) pipe coupling, a simulation approach combining finite element method (FEM) with cellular automaton (CA) was developed and the relationship between the macroscopic......
based on inorganic superconductive heat pipe dissipation methods. Simulation was performed under different conditions by using different diameters of inorganic superconductive heat pipe. The results show that the temperature of battery surface can be controlled in 20-50 ℃ after reaching stable condition using the superconductive heat pipe. The inorganic superconductive heat pipe has the best cooling......
