J. Cent. South Univ. (2018) 25: 1966-1975 DOI: https://doi.org/10.1007/s11771-018-3887-4 Effects of different numerical algorithms on simulation of chemical dissolution-front instability in fluid... and engineering problems need to use numerical methods and algorithms to obtain computational simulation results because analytical solutions are seldom available for them. The chemical dissolution-front......
through numerical and experimental study. A three-dimensional finite-volume numerical model was established under the assumption that the soil thermal conductivity had been known in the simulation of thermal response test. The thermal response curve was firstly obtained through numerical calculation. Then, the accuracy of the numerical model was verified with measured data obtained through a thermal......
