Xiao, S. Diffusion and absorption in infiltration processes. (English) Zbl 0707.76086 Free boundary problems: theory and applications, Proc. Int. Colloq., Irsee/Ger. 1987, Vol. I, Pitman Res. Notes Math. Ser. 185, 260-267 (1990). [For the entire collection see Zbl 0703.00015.] This is a brief survey of recent studies on infiltration problems of a group in Tsinghua University. The main interest of this group is qualitative analysis of the solutions to infiltration equations or systems. Three topics are concerned in this survey: 1. Diffusion with absorbtion; 2. Infiltration processes in layered media; 3. Fluid-solute- heat flow in porous media.
