Performance Analysis of Spiral Tube Heat Exchanger

In the present study, the performance of the spiral tube heat exchanger can be carried out. The heat exchanger consists of a shell and tube unit. Each coil is fabricated by bending a 12 mm diameter straight copper tube into a spiral coil tube of four turns. Cold water and hot oil are used as working fluids in shell side and tube side, respectively. The experiments are done at the cold water Performance Analysis of Spiral Tube Heat Exchanger In the present study, the performance of the spiral tube heat exchanger can be carried out.

Fluid flow and heat transfer characteristics of spiral

In addition, the Nusselt number and pressure drop per unit length obtained from the spiral-coil tube are 1.49 and 1.50 times higher than those from the straight tube, respectively. View Show abstract Heat Transfer and Pressure Drop in Wavy-Walled the pressure drop is signicantly a ected by wave amplitude and the Reynolds number. On the other hand, Bian et al. [22,23] experimentally investigated the mass transfer characteristics in wavy-walled tubes. Their results showed that mass transfer and pressure drop increases in a wavy-walled tube Heat transfer and pressure drop characteristics of finned Heat transfer and pressure drop characteristics of finned tube banks in forced convection (comparison of the heat transfer characteristics between spiral fin and serrated fin) Kiyoshi Kawaguchi.
