STUDY OF HEAT TRANSFER IN GAS FLOW IN TUBES PACKED WITH GRANULAR MATERIALS
Аннотация
In this work the results of
experimental investigation of convective
heat transfer by gases flowing in
tubes packed with granular materials
of different thermal conductivity,
different shapes and size, are shown.
Preliminaryly the critical review of
studies, published already in this
field, are given. Carried out by
authors investigations allowed more completely to study all factors, affecting
heat transfer of gases to tube wall(and
bachward) in a packed bed. This factors
are: thermal conductivity of packing,
fisical properties Of gases and heat
flux direction. The correct choice of
determining velocity of a flow and linear
demension of packing allowed to suggest
the relationships, which generalize well
the results of our experiments, and
experiments of other authors.
