چکیده

This paper details the selection of machine learning models for predicting effectiveness a heat pipe system in concentric tube exchanger. Heat exchanger experiments with methanol as working fluid were conducted. The value angle varied from 0° to 90°, values temperature 50 °C 70 °C, and flow rate 40 120 litres per min. Multiple conducted at different combinations input parameters was measured each trial. algorithms taken into consideration prediction. Experimental data divided subsets performance model analysed subsets. For overall analysis, which included all three parameters, random forest algorithm returned best results mean average error 1.176 root-mean-square-error 1.542.

A New Model for Prediction of Heat Eddy Diffusivity in Pipe Expansion Turbulent Flows

A new model to calculate heat eddy diffusivity in separating and reattaching flows based on modification of constant Prt is proposed. This modification is made using an empirical correlation between maximum Nusselt number and entrance Reynolds number. The model includes both the simplicity of Prt=0.9 assumption and the accuracy of two-equation heat-transfer models. Furthermore, an appropriate l...
