Effect of non-isothermal flow on chloride ion transport in saturated concrete [PDF]

open access: yesE3S Web of Conferences, 2021
The presence of a temperature difference changes the mode of motion of the fluid. The macroscopic motion of the fluid causes the relative displacement between the various parts of the fluid, which in turn affects the transfer of temperature in the medium.
