Impact of Darcy–Forchheimer Inertial Drag and Heat Dissipation on Micropolar Hybrid Nanofluid Flow via Expanding Surface

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The hybrid nanofluid integrated with micropolar fluid shows growing interest due to the enhanced thermal performance in microscale devices. These improved properties are due to their greater thermal conductivity and rotational effects. The proposed study assesses the significance of velocity slip on the flow characteristic of micropolar ...
