| description | Due to their outstanding heat transfer capabilities, spiral heat exchangers have attracted the attention of thermal process experts. This numerical research covers the improvement in efficiency of this kind of converter. In the current work, we selected thermal efficiency (performance evaluation criteria) as the performance index to better understand the efficiency of the intended spiral exchanger. The simulations used three fluid types in a laminar regime (200 < Re <800) and for two positive and negative flows. This paper employs computational fluid dynamics to analyze how nanohybrid fluid influences heat transmission numerically. Today, the numerical simulation results for the suggested model are compared to the experiments' results to ensure that the numerical method used in this dissertation [30] is correct. Using fluid nanohybrids and countercurrent has an enormous impact on overall performance, and it can boost the spiral exchanger's performance by 8.01 percent. The tabulator's two outlet ducts collide to form vortices, pulling the spinning flow toward the wall and causing the wall's boundary layer to collapse. |
