Review of Heat Transfer Parameters of Serrated Plat e Fin Heat Exchanger for Different Materials
Main Article Content
Abstract
fin surfaces are presented in terms
of the Colburn factor j and the Fanning friction factor f verses Rey
nolds number Re, the
relationships being different for different surfaces. The laminar
flow model predicts j and f values at
low Reynolds number; the data is throughout the range of interest. Ve
locity, and temperature fields
have been computed and j and f factors determined over appropriate r
ange of Reynolds number and
geometric dimensions. For this work I have designed heat exchange
r according to procedure of
design of serrated plate fin heat exchanger [11], correlation used
for finding various heat transfer
parameters having Reynolds number less than 200 [6]. Experimental s
etup was manufactured using
calculated parameters of design. On this setup readings were ta
ken by varying flow rate of hot oil, at
constant air for different temperatures of selected material
s. After getting readings calculations were
done for heat transfer parameters like Reynolds number, Colburn factor and Fanning f
riction factor.
