| Abstract: | An experimental study was conducted of the turbulent friction resistance and heat transfer characteristics of six copper made W type spirally fluted tubes with different structural parameters. A multivariable linear regression was undertaken of numerous experimental data along with an analysis of the major factors influencing the heat transfer and flow resistance characteristics of the W type spirally fluted tubes. As a result, a statistical correlation formula of relatively high precision has been obtained concerning the friction factor and heat transfer coefficient of the above mentioned fluted tubes. The results of the experimental study can serve as a theoretical basis for the design and technical modification of heat exchangers. |
