ABSTRACT = {Thermal transport investigation in colloidal suspensions is taking a significant research direction. The applications of these fluids are found in various industries, engineering, aerodynamics, mechanical engineering and medical sciences etc. A huge amount of thermal transport is essential in the operation of various industrial production processes. It is a fact that conventional liquids have lower thermal transport characteristics as compared to colloidal suspensions. The colloidal suspensions have high thermal performance due to the thermophysical attributes of the nanoparticles and the host liquid. Therefore, researchers focused on the analysis of the heat transport in nanofluids under diverse circumstances. As such, the colloidal analysis of H<sub>2</sub>O composed by γAl<sub>2</sub>O<sub>3</sub> and Al<sub>2</sub>O<sub>3</sub> is conducted over an elastic cylinder. The governing flow models of γAl<sub>2</sub>O<sub>3</sub>/H<sub>2</sub>O and Al<sub>2</sub>O<sub>3</sub>/H<sub>2</sub>O is reduced in the dimensionless form by adopting the described similarity transforms. The colloidal models are handled by implementing the suitable numerical technique and provided the results for the velocity, temperature and local thermal performance rate against the multiple flow parameters. From the presented results, it is shown that the velocity of Al<sub>2</sub>O<sub>3</sub>–H<sub>2</sub>O increases promptly against a high Reynolds number and it decreases for high-volume fraction. The significant contribution of the volumetric fraction is examined for thermal enhancement of nanofluids. The temperature of Al<sub>2</sub>O<sub>3</sub>–H<sub>2</sub>O and γAl<sub>2</sub>O<sub>3</sub>–H<sub>2</sub>O significantly increases against a higher ϕ. Most importantly, the analysis shows that γAl<sub>2</sub>O<sub>3</sub>–H<sub>2</sub>O has a high local thermal performance rate compared to Al<sub>2</sub>O<sub>3</sub>–H<sub>2</sub>O. Therefore, it is concluded that γAl<sub>2</sub>O<sub>3</sub>–H<sub>2</sub>O is a better heat transfer fluid and is suitable for industrial and technological uses.},
