the thermal examination of a non-integer-ordered mobile fin with a magnetism 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) configurations. the combination approach is utilized to evaluate the physical and thermal characteristics of the trihybrid and hybrid nanofluids, excluding the thermal conductivity and dynamic viscosity. these two properties are inferred by means of the interpolation method based 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 trihybrid nanofluid. the obtained results agree well with those numerical simulation results, indicating that this research is reliable. 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 combination of spherical, cylindrical, and platelet nanoparticles is higher 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%.
