Heat Transfer Features of Pulsating Turbulent Flow in a Pipe: Experimental Optimization

Abstract

The heat transmission improvement methods are widely utilized to raise the level of performance of the latent heat storage systems, the heat pipe is a broadly used technique utilized to improve the transmission of heat enhancement technique. Current paper comprises use of the heat pipe to vary the heat input, pulsating frequency, and flow velocity. The Heat input is varied in 0, 25, 50, 75 and 100 watts; pulsating frequency in upstream and downstream with frequency changed from 0 to 3.33 Hz; Flow velocity varied and calculated from Reynolds number which varies from 6000 to 13000. The experimental results were carried out using the design of experiments with output parameters as coefficient of heat transfer along with Nusselt number. The behavior of coefficient of heat transfer with respect to input parameters is discussed. The Analysis of variance is accustomed to check the reliability of the outcomes. The optimized input response selected using Particle swirm optimization shows Pulsating frequency of 3.33 Hz, Heat input of 100 W and Reynolds number of 13443 giving optimum heat transfer coefficient.
