Fractal perforating impeller was introduced to minimize the stagnation zone and enlarge the
well-mixed zone for the mixing process of shear-thinning fluids with yield stress in a stirred …

The hydrodynamics of solid-liquid mixing process in a stirred tank with four pitched-blade
impellers, fractal 1 impellers, and fractal 2 impellers were investigated using computational …

A dislocated self-similarity impeller (DS impeller) was introduced in the solid particles and
pseudoplastic fluid mixing process. The investigation on the mixing performance of a …

Previous wind‐tunnel measurements have shown that fractal‐shaped plates have increased
drag compared to square plates of the same area. In this study, the power consumption and …

The flow on the centerline of grid-generated turbulence is characterized via hot-wire
anemometry for three grids with different geometry: a regular grid (RG60), a fractal grid …

An experimental investigation was conducted into the nature of the vortex shedding
generated by truncated and nonflat serrated trailing edges of a NACA 0012 wing section as …

Gas-liquid mixing characteristics in fractal impeller stirred tank were experimentally
investigated by measuring multi-scale entropy (MSE), relative power demand (RPD), local …

The role of initial conditions in affecting the evolution toward self-similarity of an
axisymmetric turbulent jet is examined. The jet's near-field coherence was manipulated by …

Climate model parametrization relies strongly on the prediction of snow precipitation, which
in turn depends upon the snowflakes falling motion in air. The falling attitudes of such …

This study attempts to quantify the decay rates of stratified wakes in active oceanic
environments, characterized by the presence of intermittent turbulence and double-diffusive …
