ABSTRACT
The aim of this paper* is to investigate the
heat transfer problem in circular pipe flow due to a
sudden change of the outer temperature. The problem
is modeled in order to account for wall conjugation
effects. The Generalized Integral Transform
Technique is used to provide a hybrid
analytical- numerical solution furnishing accurate
results for average fluid and wall temperatures.
INTRODUCTION
The common assumption of neglecting wall heat
storage effects in transient internal forced
convection has always been questioned and i nnume r o us
contributions appeared in the literature as an
attempt to investigate this problem. Mikhailov and
Ozisik C13 present a formal solution for a general
transie
