Condensing heat transfer within horizontal tubes
The purpose of this investigation was to study the effect of vapor velocity, temperature difference and fluid properties upon the heat transfer coefficient of a vapor condensing within a horizontal tube. Condensing heat transfer coefficients for propane were measured over a wide range of …

Finite Element Analysis of Geotextile Tubes
The three-dimensional behavior of geotextile tubes is studied using finite element modeling. Two initial shapes are investigated, one with a flat length-to-width ratio of 2:1 and the other with a flat length-to-width ratio of 5:1. The tubes are modeled resting on elastic foundations. For each …

Combined mechanical loading of composite tubes
… nonlinearities on the response of composite tubes subjected to combined axial and torsional loading. An elasticity based analytical model was developed to predict stresses and deformations in composite tubes subjected to combined thermomechanical loading. Material nonlinearities were modeled …

Material Characterization of Insect Tracheal Tubes
… properties of the primary thoracic tracheal tubes of the American cockroach (Periplaneta americana). We performed quasi-static uniaxial tests on the tissue which revealed a nonlinear stress-strain response even under small deformations. A detailed analysis of the tissue's microstructural …

Falling-film evaporation over horizontal rectangular tubes
… evaporation over horizontal rectangular tubes. This geometry is representative of the external profile of microchannel tubes. Incorporating these designs into shell-and-tube heat exchangers has the potential to provide compact, high-performance components for a wide range of applications. …

Failure analysis of notched graphite-epoxy tubes
Notched unidirectional graphite/epoxy tubes with fiber orientations of 2.5°, 15°, 45°, and 87.5° were failed in tension, compression, torsion, and combined compression-torsion loading. The stress field around the slot-like notches, aligned with the tube axis, was determined using an infinite flat …
