In this research, numerical analysis will be conducted on the thermal and hydraulic performance of a spiral two-tube heat exchanger. The study employs an innovative turbulator design with curved outer blades semi-conical section two openings. Numerical simulations were using commercialized Finite Volume Method (FVM) program, ANSYS FLUENT 18.2. finite volume method was employed to analyze fluid equations parameters. A comparison made between distinct flow directions, namely positive negative currents, utilizing comprehensive range three working fluids. findings indicate that employing counter-current Water/MOS2−Fe3O4 nanohybrid results in superior endothermic performance. These maximum efficiency improvement roughly 17.54 % 8 can achieved by counterflow configuration at mass rate m˙ = 0.008 kg/s, alternative models. Furthermore, showed performs better than Ag-HEG/Water when used parallel configurations, starting Reynolds number 600. With tubes, Water/MOS2−Fe3O4fluid achieves highest coefficient
