Abstract

This research paper presents an experimental analysis on a heat exchanger tube using a newly designed perforated conical ring combined with twisted tape as inserts. The investigation analyzes various geometric and flow parameters in the experimental setup, including a wide range of Reynolds numbers, varying from 6000 to 30000, nanoparticle volume concentration (φ_np) of 0.25-1.0%, the ratio of inlet flow dia to inner print dia of the ring (D_IR/D_BR) of 1.33-2.33, ring pitch ratio (R_P/ D_ED) of 1.41-2.51, twist ratio (T_L/ W_T) of 3.33-4.38, with fixed values for other parameters: relative ring height ((D_ED/ W_R) of 2.33 and nanoparticle diameter (d_np) of 30 nm. The optimal result of the thermal-hydraulic performance parameter (η_TT) is 1.45 at D_IR/D_BR = 1.83, T_L/ W_T = 3.50 and R_P/ D_ED = 1.76. For the CuO/H₂O nanofluids flow heat exchanger tube with perforated conical rings, empirical correlations were developed for the Nusselt number and the friction factor. These correlations were established with a range of 9.0% and 8.0%, respectively.
