USE OF EMPIRICAL RELATIONS IN THE PARAMETERS OF HEAT-EXCHANGER MODELS.

Author(s) : JONSSON G., PALSSON O. P.

Type of article: Article

Summary

THE PAPER SHOWS HOW EMPIRICAL RELATIONS OF THE HEAT-TRANSFER COEFFICIENTS CAN BE INCLUDED IN THE PARAMETERS OF HEAT-EXCHANGER MODELS, THEREBY MAKING THEM VALID OVER A WIDE RANGE OF OPERATING CONDITIONS. SOME OF THE PARAMETERS IN THESE RELATIONS ARE ESTIMATED ALONG WITH THE REMAINING PARAMETERS OF THE MODELS BY USING STATISTICAL PARAMETER ESTIMATION METHODS. IT IS POSSIBLE TO USE SIMPLE MODELS WITH THIS APPRAH FURTHERMORE, THE DIFFERENCE IN THE MODEL PERFORMANCE WHEN USING STATISTICALLY ESTIMATED PARAMETERS INSTEAD OF PARAMETERS DERIVED SOLELY FROM THE GEOMETRY OF THE HEAT EXCHANGER AND STEADY-STATE CONSIDERATIONS IS DEMONSTRATED.
