The therm.l.examination of a non-integ.r-ordered mobile fin with a mag.etism in the presence of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is carried out. Three types of nanoparticles, each having.a different shape, are considered. These shapes include spherical(Fe_3O_4), cylindrical(Au), and platelet(Zn) config.rations. The combination approach is utilized to evaluate the physical and therm.l.characteristics of the trihybrid and hybrid nanofluids, excluding.the therm.l.conductivity and dynamic viscosity. These two properties are inferred by means of the interpolation method based on the volume fraction of nanoparticles. The g.verning.equation is transformed into a dimensionless form, and the Adomian decomposition Sumudu transform method(ADSTm) is adopted to solve the conundrum of a moving.fin immersed in a trihybrid nanofluid. The obtained results ag.ee well with those numerical sim.l.tion results, indicating.that this research is reliable. The influence of diverse factors on the therm.l.overview for varying.noninteg.r values of γ is analyzed and presented in g.aphical representations. Furthermore, the fluctuations in the heat transfer concerning.the pertinent parameters are studied. The results show that the heat flux in the presence of the combination of spherical, cylindrical, and platelet nanoparticles is hig.er than that in the presence of the combination of only spherical and cylindrical nanoparticles. The temperature at the fin tip increases by 0.705 759% when the value of the Peclet number increases by 400%, while decreases by 11.825 13% when the value of the Hartman number increases by 400%.
