Role of Cattaneo-Christov heat flux in an MHD Micropolar dusty nanofluid flow with zero mass flux condition

This investigation aims to look at the thermal conductivity of dusty Micropolar nanoliquid with MHD and Cattaneo-Christov heat flux flow over an elongated sheet. The novelty of the envisioned mathematical model is augmented with the added impacts of the heat source/sink, chemical reaction with slip, convective heat, and zero mass flux boundary conditions. The salient feature of the existing problem is to discuss the whole scenario with liquid and dust phases. The graphical depiction is attained for arising pertinent parameters by using bvp4c a built-in MATLAB function. It is noticed that the thermal profile and velocity field increases for greater values of liquid particle interaction parameter in the case of the dust phase. An escalation in the thermal profile of both liquid and dust phases is noticed for the magnetic parameter. The rate of mass transfer amplifies for large estimates of the Schmidt number. The thickness of the boundary layer and the fluid velocity are decreased as the velocity slip parameter is augmented. In both dust and liquid phases, the thermal boundary layer thickness is lessened for growing estimates of thermal relaxation time. The attained results are verified when compared with a published result.

Automated summary

This study examines the thermal conductivity of dusty Micropolar nanoliquid with MHD and Cattaneo-Christov heat flux flow over an elongated sheet, considering various factors such as heat source/sink, chemical reaction, and convective heat. Results show that the thermal profile and velocity field increase with higher liquid particle interaction parameter in the case of the dust phase, while the magnetic parameter and Schmidt number also affect the thermal profile and mass transfer rate respectively. Speed slip parameter has an impact on both boundary layer thickness and fluid velocity, while thermal boundary layer thickness decreases with increasing thermal relaxation time in both dust and liquid phases.
