Experimental measurement can be made only of inlet and outlet global temperature of
plate heat exchanger (PHE), therefore the temperature profile along of a PHE is hardly
ever known. The goal of this work was to evaluate the influence of a non-Newtonian
behavior of pectin solution in the temperature response curves along of the PHE. The
results were obtained using a simulation codified in Matlab 6.1 software. The response
curves resulted from the simulations were fitted to models for identification and
characterization of the system linearity. The result shows a clear non-linear behavior of
the response curves along the PHE.
