Heat Transfer In Tightly Packed Cylinder Arrays
<p>Cylindrical arrays with a cross flow are commonly used for heat transfer augmentation within an internal channel. In most applications, the cylinders have a spacing of over 2 diameters (2D) between their center points in both the lateral and downstream directions. One option for battery thermal …

Experimental Investigation of Heat Transfer to Tightly Packed Cylinder Arrays
… agreement with previous literature on short pin arrays. Data gathered show high dependence on the flow structures developed on pin-wall interfaces. A new correlation is presented for the average array Nusselt number for tightly-packed short pins.</p>

Flow and solute transport in random cylinder arrays : a model for emergent aquatic plant canopies
… and lateral dispersion of passive solute in arrays of randomly-distributed cylinders, a model for emergent, rigid aquatic plants. Mean drag per cylinder length normalized by the mean interstitial fluid velocity and viscosity increases linearly with cylinder Reynolds number. In contrast to the …

Design and fabrication of electromagnetic micro-relays using the UV-LIGA technique
… aspect ratio open field features and 45:1 intact cylinder arrays. A multi-layer SU-8 optical lithography and metal electrodeposition process was developed to fabricate the relay. The design required implementation of high aspect ratio lithographic processing techniques to produce a tall nickel …

Energy Harvesting from the Vortex-Induced Vibrations of Bluff Body Oscillators
… efficiency. For a single circular cylinder, vibration amplitude and lock-in bandwidth were found to depend primarily on the mass ratio, stiffness, and cylinder diameter. Increasing mass reduced both peak amplitude and resonance velocity, whereas larger diameters – corresponding to …

Meshless Discrete Velocity Boltzmann Model for Porous Media Flow
… cavity flow, and channel flow over a circular cylinder. These illustrate the solver's ability to address multiple boundary types, including periodic, Dirichlet, and zero-gradient boundaries. In the second manuscript, the solver is applied to address porous media. The complex multiscale nature …
