The effect of external-recycle operations on the thermal performance double-pass cross-corrugated solar air heaters (SAH) under different operating conditions was investigated experimentally and theoretically. Additionally, simultaneous ordinary equations were solved analytically for each proposed configuration. Four recycling types are introduced improving with external recycle processes, whic...

Rational design of the micro-nanomorphology is highly desired for metal hydroxides to achieve overall high-performance electrodes supercapacitor and energy storage applications. Here, in current study, we have succeeded controlling morphology Sn/Co nanolayered structures obtain plate nanofibrous morphologies. Additionally, nanostructures could be transformed plate-nanofibrous In this trend, dua...

During vessel evolution in angiosperms, scalariform perforation plates with many slit-like openings transformed into simple plates with a single circular opening. The transition is hypothesized to have resulted from selection for decreased hydraulic resistance. Previously, additional resistivity of scalariform plates was estimated to be small – generally 10% or less above lumen resistivity – ba...

Plates, which geometric and physical parameters slightly differ from constant depend only on the radial coordinate, are analyzed. For free vibration frequencies of a plate, thickness and/or Young’s modulus coordinate asymptotic formulas obtained by means perturbation method. As examples, vibrations square plate with linearly or parabolically examined. The double plates similar edge support all ...

Abstract We developed a two-stage temperature control system for long-term stable measurement of AMoRE neutrinoless double beta decay experiment using dilution refrigerator. The first-stage was made with standard PID an AC bridge ruthenium oxide thermometer as the main mixing chamber plate. second-stage obtained magnetic microcalorimeter (MMC) that is configured sensitive detector tower, experi...

The flutter instability resulting from the interaction of a flexible plate with a fluid flow is experimentally investigated. The present visualizations are obtained with two square plates (i.e. of aspect ratio H/L = 1, see the sketch of the experiment in Fig. 1.) made in a plastic sheet (of flexural rigidity 4.8 10-4 kg m 2 s-2) and of length L = 8 and 21 cm. Experiments are performed in the ho...

geometrically nonlinear governing equations for a plate with linear viscoelastic material are derived. the material model is of boltzmann superposi¬tion principle type. a third-order displacement field is used to model the shear deformation effects. for the solution of the nonlinear governing equations the dynamic relaxation (dr) iterative method together with the finite difference discretizati...
