The current study investigated unsteady boundary layer flow of a Cu/H2O$$ \mathrm{Cu}/{\mathrm{H}}_2\mathrm{O} $$ nanofluid over an expanding sheet embedded in a Darcy porous medium, containing gyrotactic microorganisms. The model includes heat source effects, unsteadiness, buoyancy, slip conditions, and nanoparticle radius.

Special‐shaped nozzles and nanofluid integration enhance jet impingement cooling by improving heat transfer and thermal uniformity. However, gains are constrained by increased pressure drop and stability challenges, highlighting the need for optimized designs and multiscale modeling to achieve efficient, scalable thermal management.

Effect of Prandtl's ration on balance in geophysical turbulence [PDF]
Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant no. EP/H001794/1).The fluid dynamics of the atmosphere and oceans are to a large extent controlled by the slow evolution of a scalar field called ...

The maximum heat transfer rate is observed at Ri = 10, Ha = 0, and ϕ = 0.06 under the default parameter settings for different boundary conditions. The proposed ANN model demonstrates good predictive and classification accuracy in estimating the average Nusselt number for both cases. ABSTRACT This computational study introduces a novel hybrid framework

Cio-cio-san no Yūutsu: memoirs of magnetogenesis and Turbulent Dynamo Theory [PDF]
The origins of cosmic magnetic fields are not as yet well understood. In this dissertation we investigate, via direct numerical simulation, the temporal evolution and behaviour of magnetic fields that are generated from absolute zero initial conditions ...

Thermal Behavior of Radiative Darcy–Forchheimer Nanofluid Flow With Heat Source/Sink Effects
Radiative Darcy–Forchheimer nanofluid flow in a porous medium is numerically analyzed with heat source/sink effects. Radiation enhances heat transfer and boundary layer thickness, while increasing Forchheimer resistance suppresses velocity, providing insights for optimizing thermal management in high‐temperature porous systems.

Flow characteristics and pressure loss mechanisms of a reverse circulation converter in dual‐wall drill pipes are systematically investigated using CFD and response surface methodology. The results reveal the dominant role of inertial dissipation and provide a predictive framework for optimizing converter design and operational parameters. ABSTRACT The
