Abstract:
The article investigates the applicability of
inverse methods in estimating the best values to be assigned to
certain parameters which appear in turbulent flow through
DPHE. The normalized study domain has been derived from
original DPHE. Conjugate gradient method (CGM) technique
is applied in the estimation of unknown heat transfer rate. No
information is available for the unknown heat transfer rate and
hence the procedure is classified as estimation of unknown
quantity using simulated temperature measurement. The
parameter optimization relies on the availability of data for the
velocity profile, friction factor, viscosity and other turbulent
parameters. It is shown that using these optimized parameters;
it is possible to predict with more the parameter profile within
the domain. The Prandtl mixing length theory model used to
solve the turbulent energy equation for parameter estimation.
Results shows that there is excellent estimation of heat transfer
rate for the test case analyzed in this study domain of Double
Pipe Heat Exchanger.
