Muitifractals in Convection and Aggregation
1988Patterns found in convection and aggregation are often multifractals and can be characterized by a continuum of exponents. This differs from critical phenomena where typically a finite number of relevant exponents is needed. The set of exponents for a multifractal is conveniently presented as an f(α) spectrum, i.e., a spectrum of pointwise dimensions ...

Forced and natural convection in aggregate-laden nanofluids
Journal of Nanoparticle Research, 2011A number of experimental and theoretical studies of convective heat transfer in nanofluids (liquid suspensions of nanoparticles, typically with features below 100 nm in size) reveal contrasting results; nanoparticles can either enhance or reduce the convective heat transfer coefficient.

Convective heat transfer performance of aggregate-laden nanofluids
International Journal of Heat and Mass Transfer, 2016With the recent progress in nanotechnology, nanofluids are emerging as a new class of heat transfer fluids formed by adding nanometer-sized structures (e.g., particles, fibers, tubes) in conventional base fluids (e.g., water, ethylene glycol, engine oil).

Spatial Aggregation Arising from Convective Processes
1993Irving Langmuir (1938) carried out the first scientific investigation of the phenomenon now called Langmuir circulation. This physical process became known to him by the spatial aggregation of biological material that it caused, which he observed as rows of Sargassum on the ocean surface during a cross-Atlantic voyage by ship. Had the patchiness in the

Aggregation study of Brownian nanoparticles in convective phenomena
Journal of Thermal Analysis and Calorimetry, 2018The explanation of abnormal enhancement of transported energy in colloidal nanoparticles in a liquid has sparked much interest in recent years. The complexity comes from the inter-particle phenomenon and cluster formation. The process of nanoparticle aggregation, which is caused by convective phenomena and particle-to-particle interaction energy in a ...

Self‐aggregation of convection in long channel geometry
Quarterly Journal of the Royal Meteorological Society, 2015Cloud cover and relative humidity in the Tropics are strongly influenced by organized atmospheric convection, which occurs across a range of spatial and temporal scales. One mode of organization that is found in idealized numerical modelling simulations is self‐aggregation, a spontaneous transition from randomly distributed convection to organized ...
