In this study, the effects of the Al2O3 water nanoplastic fluid on the heat transfer and drilling factor of the Al2O3 water nanoplastic fluid that passes through fixed wall temperatures have been numerically studied. In the study, circular cutting pipes were gradually placed and analyses were carried out in two-dimensional forms. The equations used are resolved using the SIMPLE algorithm with the final volumes method. In numerical studies, the nanoplastic type and particle volume ratio were kept stable, and the analyses were obtained by changing the pulsative parameters for a fixed value of the Reynolds number. The temperature transfer characteristics and effects of these parameters on the drilling factor are compared with the permanent flow conditions. Instant speed and temperature distribution is obtained through the pipe set in the pulsative flow. Numerical results have shown that healing in heat transfer is highly affected by the pulsative parameters. As the pulse width and frequency increase, the heat transfer is also increased, but this increase has also been observed to cause some increase in the drainage factor. The results of the study have determined the parameters that provide the best thermo-hydrolic performance for the pulse flow of nanoparks through the pipeline sets. The results are given as a function of non-dimensional parameters.
