# A numerical analysis of the water-based ternary hybrid nanofluid between two rotating disks subject to thermal radiation and homogeneous–heterogeneous reactions

## TL;DR

This study numerically analyzes the flow of a hybrid nanofluid between rotating disks, considering thermal radiation and chemical reactions, to optimize thermal systems.

## Contribution

The novelty lies in analyzing tri-hybrid nanofluid flow with thermal radiation and homogeneous-heterogeneous reactions between rotating disks.

## Key findings

- Axial flow increases with the stretching factor at the bottom disk, while radial flow shows a twofold behavior.
- Thermal profiles increase with higher Eckert, Reynolds, magnetic, and radiation parameters.
- Concentration decreases with increased homogeneous and heterogeneous factors and Schmidt numbers but increases with Reynolds number.

## Abstract

This work involves detailed numerical research on tri-hybrid nanofluid flow that takes place between two gyrating disks with integrated effects of the magnetic field, Joule heating, thermal radiation, as well as, homogeneous-heterogeneous reactions. The main equations have solved through bvp4c approach in dimensionless from. It has found in this work that the stretching factor at the bottom disk increases the axial flow, and the radial flow exhibits a twofold action. Axial and tangential velocities are directly proportional to Reynolds number but inversely proportional to the effects of the magnet whereas radial velocity is a mixed proportion. The rotational factor of tangential flow increases. Thermal profiles increase as Eckert, Reynolds, magnetic and radiation parameters increase. The concentration undergoes a decreasing trend when the homogeneous factors, heterogeneous factors and Schmidt numbers are increased and an increasing trend when Reynolds number is increased. There is great congruence in comparative results and Nusselt and Sherwood number are measured in tables and are used to determine the heat and mass transfer. This study contains useful information on how to optimize reactive thermal systems using rotating geometries and multimodal nanofluids, and can find its applications in energy systems and chemical reactors as well as innovative cooling technologies.
