Abstract
Helical coils are commonly employed in a variety of process industries due to their superior fluid mixing capabilities, the flexibility of fabrication, and simple design. Frictional pressure losses occur in flow-through helically coiled tubes, affecting the heat transfer rate across the coils. An inquiry is carried out in the current experimental study to discover friction factors and heat transfer rates within the coil tubes of test fluids flowing in the laminar flow area. Non-Newtonian test fluids comprised ichorous solutions of Carboxy Methyl Cellulose (CMC) at concentrations of 0.5 percent, 1 percent, and 2 percent, whereas Newtonian test fluids consisted of water. With the use of an appropriate viscosity expression, Newtonian consonances are demonstrated to apply to several non-Newtonian fluids with certain constraints. In a laminar flow, the shear stress in a helical coil is greater than in a straight conduit. It has been proved that the experimental data can be fruitfully correlated across a broad extent of fluid data and coil radius stretch. The investigated data obtained has been correlated with Standard a deviation of 15.6% with the range 25<D_e < 2000 and 40<P_r < 226.
