Abstract

In the present study the effect of pulsation was investigated on the heat transfer in a helical tube. The flow is laminar, Newtonian, unsteady and three dimensional. The governing equation is solved in the commercial software Fluent 6.3 and the results are discussed by temperature, and pressure contours and Nusselt number. The effect of amplitude and frequency of pulsation, tube pitch and tube helix ratio were investigated on the Nusselt number. The results show that as the pulsation amplitude increases, the amplitude of Nusselt curves experience a significant augmentation. The increase of frequency yields the increase of average Nusselt number. The heat transfer rate increases as the ratio of helix to the tube diameter decreases.
