The inner-tube arrangement has an important impact on the performance of latent thermal energy storage heat exchangers, but effect spacing not been widely concerned. This study simulated numerically charging and discharging processes horizontal dual-inner-tube exchangers researched effects parameters exchangers. studied included phase change time material, rate, rate. results show, as increases...

In the past, fin-and tube heat exchanger (FTHE) pattern ratios have been largely based on ad-hoc design principles. Here, we investigate optimal arrangements for a FTHE with plain fins in marine environments represented by two different air types; one unfiltered high condensation rate and clean dry filtered conditions. The thermal-hydraulic efficiency of is measured comparing modified ratio Col...

Since the original publications by Martini et al. (Dtsch. Arch. Klin. Med. 169: 212-222, 1930) and Fahraeus and Lindqvist (Am. J. Physiol. 96: 562-568, 1931), it has been known that the relative apparent viscosity of blood in tube flow depends on tube diameter. Quantitative descriptions of this effect and of the dependence of blood viscosity on hematocrit in the different diameter tubes are req...

Heat transfer coefficients were measured in a circular tube with dimpled surface. The almond type dimples were fabricated, the tube diameter (D) 19mm and dimple depth 3 mm ratio was kept constant, while holding diameter 10mm of dimple is required length 21.5mm because of the elongated shape. The Reynolds number based on the channel hydraulic diameter was varied from 25000to 95000. An experiment...

• Capillary tubes & SAW devices used to pattern particles in no-flow flowing setups Rectangular tube: particle lines are parallel tube sidewalls for all directions Circular alignment depends on their position along the height Bottom/mid height: parallel/perpendicular direction Continues flow: always flow Acoustofluidic platforms have great potentials integrate capillary controlling and manipula...

The stratum and microenvironment temperatures in a greenhouse are important factors that affect crop yield. In order to solve the problem of temperature imbalance caused by solar radiation greenhouses, this paper proposes application array tube greenhouse. By adding water or phase change materials tube, influence on formation changes was studied, 10-day test carried out. A group control were se...

To solve the problem of low-frequency noise in environment, a Helmholtz-type phononic crystal with adjustable cavity structure and labyrinth tubes was designed. The unique design tube greatly increases length tube, improving sound insulation performance, realizes active regulation band structure. gap characteristics were analyzed by finite element method (FEM) electro-mechanical-acoustic analog...

The blood brain barrier (BBB) has evolved unique characteristics such as dense coverage of the endothelial cells by pericytes and interactions with astrocytes through perivascular endfeet. We study BBB formation in a 3-dimensional multicellular spheroid system of human primary brain endothelial cells (hpBECs), primary pericytes (hpPs) and primary astrocytes (hpAs). We show for the first time th...

This work shows the application of a validated mathematical model for gas permeation at high temperatures focusing on demonstrated scale-up design for H2 processing. The model considered the driving force variation with spatial coordinates and the mass transfer across the molecular sieve cobalt oxide silica membrane to predict the separation performance. The model was used to study the process ...
