Abstract

In this manuscript, heat transfer enhancement in helically coiled tubes has been investigated numerically and experimentally. Experiments were conducted for immersed helical condenser coil with constant diameter. While for the numerical investigation, the studies were conducted for the immersed condenser coil with conical shape and variable pitch coils. In this study, the effects of the helical condenser coil design on the water temperature and the water velocity have been performed. According to the proposed models, the thermal performance of the helical coil, conical coil and variable pitch coils were compared. The results indicated that the water temperature and the water velocity of variable pitch coils are higher than the conical coil and the constant diameter coil. This work provides that the immersed condenser coil in the water tank is more adequate to have a variable pitch coil.
