Popis:	In this work, we consider a heat transfer problem between two periodic connected media exchanging a heat flux throughout their common interface. The interfacial exchange coefficient λ is assumed to tend to zero or to infinity following a rate λ=λ(e) when the size eof the basic cell tends to zero. Three homogenized problems are determined according to the value of δ=lime0λ/e. Copyright © 2004 John Wiley & Sons, Ltd.
