We consider flow-through systems in which the characteristic length is limited such that turbulent flow is not reached even at high fluid velocities, i.e., the flow remains laminar. Inthese flow regimes, inducing circulation or vortices in the flow enhance ...
Recent advances in boundary-layer meteorology are beginning to allow the study of atmospheric flow phenomena that have previously been poorly understood. In this dissertation, we study the effects of complex terrain and unsteady regimes on the atmospheric ...
In many engineering applications, heat transfer enhancement techniques are of vital importance in order to ensure reliable thermal designs of convective heat transfer applications. This study examines experimentally the heat transfer characteristics on the ...
This study shows the results of an experimental investigation of personal exposure to cough released droplets. Human body is resembled by a thermal manikin with a body shape and surface temperature distribution of a real person. The objective of the study ...
During the dry season of the year 2002, convective cooling triggered the formation of a double-diffusive regime of the convective type below the chemocline at 52m depth in Lake Nyos. Since then, the vertical extent of the double-diffusive staircase has con ...
In this paper, we introduce a novel sensor scheme which merges nano-photonics and nano-fluidics on a single platform through the use of free-standing photonic crystals (PhCs). PhCs offer great freedom to manipulate the spatial extent and the spectral chara ...
This study aims to characterize human convective boundary layer (CBL) in a quiescent indoor environment. The study has two objectives: first, to characterize the velocity field around the thermal manikin under two ambient temperatures and body postures; an ...
We introduce a novel sensor scheme combining nano-photonics and nano-fluidics on a single platform through the use of free-standing photonic crystals. By harnessing nano-scale openings, we theoretically and experimentally demonstrate that both fluidics and ...
Heat convection from the uniformly heated walls of a straight channel in presence of a rotationally oscillating cylinder (ROC) is simulated at Re = 100. Heat transfer enhancement due to vortex shedding from the ROC is investigated. Systematic studies are p ...
Transport of proteins in liquid-filled nanometer-sized apertures with charged surfaces based on both diffusion and convective flow is investigated with the use of fluorescence correlation spectroscopy. The measured fluctuations of fluorescence allow the ev ...
