The thermal examination of a non-integer-ordered mob.le fin with a magnetism in the presence of a trihyb.id nanofluid(Fe_3O_4-Au-Zn-b.ood) 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) configurations. The comb.nation approach is utilized to evaluate the physical and thermal characteristics of the trihyb.id and hyb.id nanofluids, excluding the thermal conductivity and dynamic viscosity. These two properties are inferred b. means of the interpolation method b.sed on the volume fraction of nanoparticles. The governing 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 trihyb.id nanofluid. The ob.ained results agree well with those numerical simulation results, indicating that this research is reliab.e. The influence of diverse factors on the thermal overview for varying noninteger values of γ is analyzed and presented in graphical 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 comb.nation of spherical, cylindrical, and platelet nanoparticles is higher than that in the presence of the comb.nation of only spherical and cylindrical nanoparticles. The temperature at the fin tip increases b. 0.705 759% when the value of the Peclet numb.r increases b. 400%, while decreases b. 11.825 13% when the value of the Hartman numb.r increases b. 400%.
