Unexpected responses of physical systems to external stimuli can be observed when the
stimuli are organized into spatial patterns and, especially, when stimuli of different physical …

Pressure-gradient-driven flows in grooved horizontal channels were investigated. The
results show that a significant reduction in pressure losses can be achieved by exposing …

An analysis of natural convection in a horizontal, geometrically non-uniform slot exposed to
spatially non-uniform heating has been carried out. The upper plate is smooth and …

A spectrally accurate and very efficient algorithm suitable for prediction of pressure losses in
heated grooved channels has been developed. Heating and topography patterns are used …

It has been recently shown [A. Abtahi and JM Floryan,“Natural convection and thermal drift,”
J. Fluid Mech. 826, 553 (2017)] that a horizontal flow, the thermal drift, can be created by …

An analysis of natural convection in horizontal slots has been carried out. It is demonstrated
that a proper combination of heating and groove patterns can create a net horizontal fluid …

An analysis of heat transfer in non-uniformly heated corrugated slots has been carried out. A
sinusoidal corrugation is placed at the lower plate that is exposed to heating consisting of …

We report on a high‐fidelity, spectral/hp element algorithm developed for the direct
numerical simulation of thermal convection problems. We consider the incompressible …

A highly accurate and fully implicit algorithm for analyses of transient effects in heated
grooved channels, including chaotic responses and transition to secondary states, has been …
