| Summary: | Heat exchangers are devices built for efficient
heat transfer fiom one fluid to another and widely used
in engineering process. The four heat exchangers consist
of shell and tube, spiral, concent~ic (double pipe), and
plate heat exchangers available in UTHM Laboratory.
This paper 1s aim to identify model nonlinear of the four
heat exchanger types. To identify this model, need to use
mathematical models of dynamic system using measule
the input and output signal of the real system. The
process identification requires select model structure,
parameter estimatio~i and model validation. ARX
(autoregressive with exogenous input) model structure is
chosen to fitting criterion and parameter estimation
determined and the data measured from the real system
will be used model validation. The M-File MATLAB
program has generated to siniulale this model to analyze
the heat exchangers performance and the best model of
these heat exchangers is obtained that based on the
fitting which more than 50% and was close to 100%. |
