Exploring the Effects of Reduced Gravitational Field Impacts on Convective Heat Transfer: A Comprehensive Review

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.
ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Energy Transport Analysis of Bioconvective Magnetized Micropolar Fluid Flow Over a Porous Curved Stretching Surface With Homogeneous–Heterogeneous Reactions

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Efficient energy transport in complex fluids is essential for the optimal design of modern thermal and bio‐energy systems. In this study, the bioconvective flow and heat transfer characteristics of a two‐dimensional, incompressible magnetized micropolar fluid of second‐grade nature over a porous curved stretching surface are investigated.

Synchronization of flexible sheets

, 2011
When swimming in close proximity, some microorganisms such as spermatozoa synchronize their flagella. Previous work on swimming sheets showed that such synchronization requires a geometrical asymmetry in the flagellar waveforms.

Two‐Layered Immiscible Flows of Carreau and Carreau Nanofluid in an Inclined Channel With Nonlinear Boussinesq Approximation and Viscous Dissipation

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
The current study discusses the laminar, incompressible steady flows of Carreau fluid and Carreau nanofluid in an inclined channel with two regions. In Region‐I, Carreau fluid is considered, whereas in Region‐II, Carreau nanofluid is deliberated. Both regions are considered porous, with a constant pressure gradient.

Structure and time-dependence of quantum breathers

, 2005
Quantum states of a discrete breather are studied in two ways. One method involves numerical diagonalization of the Hamiltonian, the other uses the path integral to examine correlations in the eigenstates.
