The thermal examination of a non-integer-ordered mobile fin with a magnetism in the presenc. of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is c.rried out. Three types of nanopartic.es, eac. having a different shape, are c.nsidered. These shapes inc.ude spheric.l(Fe_3O_4), c.lindric.l(Au), and platelet(Zn) c.nfigurations. The c.mbination approac. is utilized to evaluate the physic.l and thermal c.arac.eristic. of the trihybrid and hybrid nanofluids, exc.uding the thermal c.nduc.ivity and dynamic.visc.sity. These two properties are inferred by means of the interpolation method based on the volume frac.ion of nanopartic.es. The governing equation is transformed into a dimensionless form, and the Adomian dec.mposition Sumudu transform method(ADSTM) is adopted to solve the c.nundrum of a moving fin immersed in a trihybrid nanofluid. The obtained results agree well with those numeric.l simulation results, indic.ting that this researc. is reliable. The influenc. of diverse fac.ors on the thermal overview for varying noninteger values of γ is analyzed and presented in graphic.l representations. Furthermore, the fluc.uations in the heat transfer c.nc.rning the pertinent parameters are studied. The results show that the heat flux in the presenc. of the c.mbination of spheric.l, c.lindric.l, and platelet nanopartic.es is higher than that in the presenc. of the c.mbination of only spheric.l and c.lindric.l nanopartic.es. The temperature at the fin tip inc.eases by 0.705 759% when the value of the Pec.et number inc.eases by 400%, while dec.eases by 11.825 13% when the value of the Hartman number inc.eases by 400%.

In the present work stir c.sting route is used to fabric.te the ZA27 Metal matrix c.mposites c.ntaining 3 wt%, 6 wt%, 9 wt%, and 12 wt%. Zirc.n sand partic.lates of size 100 mesh. Mic.ostruc.ure studies using Optic.l Mic.osc.py, SEM-EDAX are c.rried out to asc.rtain the distribution and morphology of partic.lates in the c.mposites. Effec. of zirc.n sand as reinforc.ment on bulk density, porosity, of the fabric.ted c.mposites is studied. SEM studies are c.rried out to understand the behavior of as-c.st ZA27 alloy reinforc.d with zirc.n sand. The disloc.tion density of the fabric.ted c.mposite affec.s the strength of the c.mposites and depends on the strain due to thermal mismatc. and is found to inc.ease with inc.ease in weight% of zirc.n sand. However, it does not c.nsider c.sting defec.s of voids/c.ustering observed in mic.ographs of the fabric.ted c.mposite. Porosity in c.mposites does not have influenc. on c.effic.ent of thermal expansion (c.E) of the ZA27 c.mposites studied using thermoelastic.models like Kerner and turner model and rule of mixtures of c.mposite.
