Investigation evaluation of thermo-hydraulic flow and heat improvement in a 3D circular corrugated pipe based on response surface method and Taguchi analyses

Current research is investigating the effect of different tube geometries on flow patterns and thermal performance. Perform numerical simulations and thermo-fluid couplings. Calculation results are calculated and the solution uses both flow transport and thermal correction. Results are compared and validated using experimental results. Hydraulic and heat flow behaviors in all corrugated tubes are studied and discussed under various constitutive parameters of position and shape. The turbulent fluid flow in these tubes is modeled using 3D numerical flow domain simulations and the optimization of the multilens algorithm is analyzed. The effects of various geometric design parameters such as ring diameter, spacing between each well ring, and number of well rings around the tubing spacing of the rings were analyzed using Response Surface Methodology (RSM) and Taguchi Method (TM). Analyzed. be studied. The effects of changes in flow structure, such as velocity magnitude and radial velocity, and velocity magnitude and radial velocity profiles in different configurations, are studied. An experimental design strategy using the Taguchi method (TM) is chosen according to the variance of the orthogonal L16 sequences. Optimization results show that higher differential pressure values are related to shaft diameter. Therefore, the number of corrugated rings has a great effect on the heat transfer rate and temperature difference. Various configurations of Conduit Performance Evaluation Factor (PEF) increased the PEF value by more than 1.3.
