Novel thermal aspects of hybrid nanofluid flow comprising of manganese zinc ferrite MnZnFe2O4, nickel zinc ferrite NiZnFe2O4 and motile microorganisms

Ain Shams Engineering Journal, 2022
An enhancement in heat transfer due to nanofluids is essentially required in various thermal systems. Hybrid nanofluids possess high thermal conductivity and, have ability to embellish and enhance the thermal strength of common fluids.

Bioconvective gyrotactic microorganisms in third-grade nanofluid flow over a Riga surface with stratification: An approach to entropy minimization

Open Physics, 2023
Interest in the thermal effects of nanofluid (NF) has increased recently due to the use of nanocomposites to magnify the thermal conductivity of conventional liquids and so boost the heat transit phenomena.

Clustering of gyrotactic microorganisms in turbulent flows

, 2012
We study the spatial distribution of gyrotactic microorganisms transported by a three-dimensional turbulent flow generated by direct numerical simulations. We find that gyrotaxis combines with turbulent fluctuations to produce small scales (multi-)fractal clustering.
