N2 - Statistical model development of operational parameter influence on Thermal Contact Resistance (TCR) in bimetallic L-type finned tubes is presented in this work. The Group Method of Data Handling (GMDH) scheme was utilized to develop a correlation that encompasses most important operational parameters including variation of temperature difference between hot inner flow and cooling air, influence of maximum operational temperature, and effect of repeated heating-cooling cycles. Using experimental data obtained on Cuprum-Aluminum L-type finned tubes and special calculations with the help of the developed model formulae, have permitted the estimating of degree of every parameter influence upon final function. It was found that maximum operational temperature has most influence on the TCR. Such results may be useful for a practical thermal design, and operation of heat exchangers based on bimetallic L-type finned tubes.
