Abstract
This study, which has been motivated by the recent applications of the cold plate
device in aviation thermal management, reports on physics-based mathematical models
derived from the conservation laws of mass, momentum, and energy, and empiricism-based
models. One of the objectives of the present work is to report on an elaborate and
successful experimental work carried out on an additively manufactured device for
the purpose of rigorously validating the numerical predictions. The excellent agreement
between the numerical predictions and measured performance provides much needed confidence
in the implementation, in the software package, of the offset-strip fin passage correlations,
as well as in the software implementation of user-defined wavy fin correlations for
aerospace heat exchangers and cold plates operating with ram air at Reynolds numbers
below 8000. The contributions of this work can also be found in the development of
a new and accurate thermal-hydraulic analysis procedure, referred to in this paper
as plate-fin analogy. Results from this procedure are compared with those from thermal
resistance network. The comparative study in this paper of the bulk and discrete enthalpy
flux method is also new, as is the relative assessment of four off-set strip fin thermal-hydraulic
models.
