An algorithm for simulation of the performance of air-cooled heat exchanger applications subject to the influence of complex circuitry

The present study develops an index technique to take into account the effect of complex circuitry on the design of fin-and-tube heat exchangers. A 4-index array technique is described in detail that is capable of handling complex circuitry up to second-order level. In addition, a complete modeling of the performance of an evaporator is made. For the performance of evaporations without curved configuration, the proposed model can give good calculations with the experimental data.
