Shell and spiral tube heat exchangers are widely favored in refrigeration and applications such as heat recovery systems, food processing, and heat storage. Researchers' primary focus is to discover a simple and cost-effective approach to improve the efficiency of heat exchangers. The research employed a specially designed shell and spiral tube heat exchanger to enhance efficiency. This research involved utilizing ANSYS FLUENT CFD software to analyze the thermodynamic efficiency and predict heat transfer in the specified converter. The analysis incorporated factors such as displacement velocity coefficient and friction coefficient. Researchers are focused on finding a simple and cost-effective approach to improve the efficiency of heat exchangers. Furthermore, the selection of nanohybrid fluids is a crucial factor influencing the thermohydraulic performance of shell and spiral tube heat exchangers. Among the three fluid nanohybrids chosen for simulation, the water nanohybrid exhibited superior temperature performance, surpassing all other liquids. Furthermore, the optimal thermal performance for the hybrid nanofluid was observed at φ1 = φ2 = 0.7.
