Editors: László Kiss and Lyne St.-Georges, Université of Québec à Chicoutimi, Québec, Canada. ISBN: , ©, pages, 6×9, Hardcover   The present paper deals with the effect of geometry of filler particles on the effective thermal conductivity for polymer composites. In the earlier models, less emphasis has been given on the shape of filler particles. In this paper, expressions for effective thermal conductivity has been derived using the law of minimal thermal resistance and equal law of the specific equivalent thermal ?PaperID=&JournalID=
