The current study focuses on examining the transient thermal performance of a dovetail fin structure that is completely immersed in a trihybrid nanofluid and is formulated by the combination of 
, and 
nanoparticles with the hybrid base fluid 
The fin's porous medium is modelled using Darcy's law to simulate the interaction between the fluid and the solid. The resulting nonlinear partial differential equation is converted into a non-dimensional form and resolved using the finite difference method (FDM) to understand the physical implications of the model. Factors like surface convection 
, radiation 
and internally generated heat 
have been considered in assessing the fin's heat exchange. This investigation highlights the impact of variables such as tip tapering, dimensionless time, inclination angle, full wet condition, porosity, internal heat generation, and ambient temperature on the fin's thermal profile. The efficiency of the fin structure is graphically explored and discussed. Compared to mono and binary hybrid nanofluids, the trihybrid nanofluid demonstrates superior thermal response and notably the introduction of the trihybrid nanofluid significantly enhances the fin's efficiency. Dovetail fin conjunction with the trihybrid nanofluid provides superior heat transfer rate because increase in the surface area is the major finding of this study. These findings are crucial for improving heat transfer in various industrial settings. Moreover, this advancement holds the potential to revolutionize cooling and heating processes in sectors like automotive and aerospace engineering.
