Heat transfer enhancement in Marangoni convection and nonlinear radiative flow of gasoline oil conveying Boehmite alumina and aluminum alloy nanoparticles

Present analysis is made to communicate the Marangoni convection flow of hybrid nanomaterials by an infinite porous disk. Hybrid nanomaterials comprise of gamma ALOOH and AA7075 nanoparticles and gasoline oil is considered. Darcy-Forchheimer law is utilized. Thermal field is quadratically varies on disk surface. Irregular heat source, radiation, dissipation effects are further considered to investigate the thermal field. The modeled system is dimensionless by the application of Von Kamran variables. NDsolver scheme approximated the reduced system. For the analysis of surface temperature gradient, temperature and velocity various physical variables are designed through graphs and table. It has been found that hybrid nanomaterials have highest thermal conductivity when compared with traditional liquid and nanoliquid.

Automated summary

This study presents an analysis of the Marangoni convection flow of hybrid nanomaterials in an infinite porous disk. The hybrid nanomaterials consist of gamma ALOOH and AA7075 nanoparticles, and gasoline oil is used as the base liquid. The Darcy-Forchheimer law is employed and the thermal field on the disk surface is assumed to vary quadratically. The effects of irregular heat source, radiation, and dissipation are also taken into account. The system is dimensionless using Von Kamran variables and the NDsolver scheme is used to approximate the reduced system. Various physical variables such as surface temperature gradient, temperature, and velocity are analyzed through graphs and tables. It is found that hybrid nanomaterials exhibit the highest thermal conductivity compared to traditional liquid and nanoliquid.
