A pressure regulator which maintains a constant ratio of pressures at two gas outlets is described. The device consists of three chambers, a central reference chamber; and two side chambers, each one separated from the central one by a double diaphragm. The two double diaphragms are connected to two valves that control the respective gas flows into the side chambers. ...

The design and performance analysis of axial fan blades in unitary air conditioning systems are investigated numerically. The effect of propeller diameter, number of blades and blade pitch (angle of attack) on the air flow rate, static pressure rise and static efficiency are examined by solving the full three-dimensional flow equations across the fan blade. The tested configurations included 18" ...

A pressure regulator which maintains a constant ratio of pressures at two gas outlets is described. The device consists of three chambers, a central reference chamber; and two side chambers, each one separated from the central one by a double diaphragm. The two double diaphragms are connected to two valves that control the respective gas flows into the side chambers. In this way, the pressures in the side chambers are governed by the pressure in the central reference chamber. The individual diaphragms of one double diaphragm are of identical diameter; whereas, the other double diaphragm consists of two single diaphragms of different diameters. The areas of these diaphragms determine the constant ratio of the outlet pressures from the side chambers.
The design and performance analysis of axial fan blades in unitary air conditioning systems are investigated numerically. The effect of propeller diameter, number of blades and blade pitch (angle of attack) on the air flow rate, static pressure rise and static efficiency are examined by solving the full three-dimensional flow equations across the fan blade. The tested configurations included 18" [46 cm] to 24" [61 cm] propeller diameters, 2 to 4 blade propellers, and a pitch range of 25 to 35 degree. It was found that peak static efficiency was highest in the pitch range of 40 to 45 degree. The static efficiency decreased with the increase in number of blades. The static efficiency was insensitive to the propeller diameter, resulting in a flat curve in the range of the tested diameters. The increase in propeller diameter had the most pronounced effect in increasing the air flow rate. The increase in blade pitch, in the optimum pitch range, delivered the maximum increase in the static pressure rise. The results show that the best performance of the propeller occurs at the maximum possible diameter, within the physical constraint of the unit, using the least number of blades at the optimum pitch range.
In this paper, a novel concept of CDP (Combined Desalination and Power Generation System) is investigated experimentally, and the paper mainly compares the performance of the three nozzles of spray, orifice and Convergent-Divergent Nozzle. The results shows that the CDP system is proved effective even use the temperature down to 50°C of the feeding saline. The shape of the nozzles is vital to the thrust during the tests the convergent- divergent nozzle is found best and orifice is worst, while to the percentage of fresh water production, there is no obvious difference.
A functional hierarchical model for fault diagnosis is presented. In this approach, the fundamental analysis of the focal point of action of an entire system serves as the root of a functional structure. The functional interrelationships between the root component and the rest of the components in the device are used as a knowledge source for the functional model. A measure based on the complexity of the change or repair procedure and the accessibility of a component is introduced as a facility index. The opinion of an expert and the facility index are combined and used to form a functional hierarchical model. A welding system with numerous functional parameters is shown as an example to illustrate the model.<<ETX>>
We report clog-free and oxide-free metal inkjet printing applicable to flexible electronics using gallium-based liquid metal alloy. Inkjet printing has been developed and expanded to make a pattern of either non-conductive or conductive materials. In order to print typical conductive material, it utilizes metal nanoparticle dispersed in solvent or melts the metal. However, those methods often encounters clogging and oxidation problem. We fabricated a simple polydimethylsiloxane (PDMS) based inkjet printer incorporated with hydrochloric acid (HCl)-impregnated paper as orifice material. A constant stream of gallium-based liquid metal alloy droplet was demonstrated using the inkjet printer. Depending on the applied flow rate, pinch off and Rayleigh instability phenomena were observed. We printed beads-on-string shape gallium- based liquid metal alloy line on various flexible substrates such as Si wafer, PDMS, and a paper. Finally, it was demonstrated that the inkjet-printed gallium-based liquid metal can maintain its line shape without disconnection even with the significant deformation of a flexible paper.
We present the first hollow out-of-wafer-plane silicon microneedles having openings in the shaft rather than having an orifice at the tip. These structures are well suited for transdermal microfluidic applications, e.g., drug or vaccine delivery. The developed deep-reactive ion etching (DRIE) process allows fabrication of two dimensional, mechanically highly resistant needle arrays offering low resistance to liquid flows and a large exposure area between the fluid and the tissue. The presented process does not require much wafer handling and only two photolithography steps are required. Using a 3/spl times/3 mm/sup 2/ chip in a typical application, e.g., vaccine delivery, a 100 /spl mu/l volume of aqueous fluid injected in 2 s would cause a pressure drop of less than 2 kPa. The presented needles are approximately 210 /spl mu/m long.
The orifice type radial aerostatic bearing was taken as the subject. The flow field under different eccentricity and rotation speed was calculated with the three-dimension method. The influence of orifice types on characteristics of aerostatic bearings was analyzed under high-speed working conditions. For the orifice-compensated type, the influence of installation types of them on their characteristics was also discussed. The results indicate when the eccentricity is big, the orifice-compensated aerostatic bearings have a bigger main gas film stiffness and a smaller cross gas film stiffness because of the dynamic effect. The gas consumption of the orifice-compensated type is smaller than that of the orifice-restricted type with the same supply hole diameter. For the orifice-compensated type, with the increase of the number of gas supply holes, the influence of installation types decrease and can be ignored within the normal design range.
While the majority of exercise machines use weights, springs or spinning fans to generate motion resistance, a large number of machines also utilize linear fluid damping. Similar to a shock absorber, linear dampers are compact, extremely reliable, and produce "double positive" resistance (resistance to both directions of motion). However, they are difficult to adjust for higher or lower resistance. This paper illustrates a mechanism to vary the resistance of a linear damper, and illustrates with experimental data certain properties of the damper
