ShareExperimental investigation of heat transfer and pressure drop augmentation for laminar flow in spirally enhanced tubes.
Author(s) : RAINIERI S., FARINA A., PAGLIARINI G.
Summary
The effect of the internal helical ridging on the heat transfer coefficient and friction factor is experimentally investigated for laminar internal flow of a Newtonian fluid in the case of uniform wall heat flux. Five different geometries are considered. The results are compared with previous investigations and with the predictions for the smooth tube in order to point out the heat transfer enhancement and the friction increase on the laminar flow field.
