Circular chambers

Upon entering, you find yourself in an empty semi-circular chamber, which is the vestibule to the place of power itself. Do not be deceived by its emptiness it is only the spacious quality of Akasha. The guardian of this chamber—when she or he comes—will be of critical importance in advanced aspects of the Work. Set in the eastern wall is a life-sized representation of tarot Key 1, The Magician. It is fashioned, like the others in the central column, of stained glass, and is lit from behind. The only way to enter the Nuptial Chamber proper is to become the Magician to take on the mode of consciousness this tarot key represents. 

Axial and swirling air streams in the combustor issued from a circular chamber through a conical nozzle. The chamber was utilized both as an acoustic resonator and a settling chamber. It contained a honeycomb to straighten the how and two acoustic drivers to apply acoustic excitation to the jet. The nozzle exit diameter was 3.8 cm and the maximum Reynolds number based on this diameter and the exit velocity with and without air forcing was 4800 and 1400, respectively. The tests were performed with total air how rate of 85 1/min, and fuel how rate of 0.063 1/min. The swirl was applied with tangential air injection and the maximum swirl number tested was Ns = 0.30. 

Self-circulation in a circular chamber was used for mixing. It was found by simulation and flow visualization that mixing was more effective in a hollow chamber than an annular one [484]. 

The process involves feeding the drug substance into a confined circular chamber where the powder is suspended in a high velocity stream of air. Interparticulate collisions result in a size reduction. Smaller particles are removed from the chamber by the escaping air stream towards the centre of the mill where they are discharged and collected. Larger particles recirculate until their particle size is reduced. Micronized particles are typically less than 10 um in diameter (Midoux et al. 1999). 

Long et al. [129], They used an easily fabricated 3D structure comprising a circular chamber in which inlet and outlet channel are coimect tangentially. When the two liquids to be mixed flow in the circular chamber, a vortical motion is generated. The vertical motion provides distortions and elongations of material interfaces and high mixing efficiency at relatively low Re Re > 21). 

The research was conducted in a cold-flow combustor test rig simulating the exact geometry of the hot combustion rig. This test rig (Fig. 10.1) is set up vertically. The air is introduced at the bottom and is conditioned through an air conditioning section which is composed of perforated cone, screens, and honeycomb is settled in 3.8-inch diameter circular chamber is fed into TARS and then exits to the atmosphere. The pressure drop across TARS is 4%. The TARS features three separate airflow passages and independent liquid fuel supply lines that can be controlled separately (Fig. 10.2).

The rotational circular chambers in an open system (Fig. 4) comprise a motor that rotates the chromatographic plate and a system for supplying the mobile phase, which is positioned perpendicularly to the chromatographic plate s center. 

The circular TLC is used for resolution increase in compounds with low Rp, the circular multiple developments are frequently used for separation of compounds with Rp less than 0.5. The anti-circular TLC is advantageous for the separation of compounds with high Rp values. The circular TLC can be performed in a closed system, on Petri dish, or in an open system, rotational circular chamber. Circular TLC was used with success for separation of bioactive compounds from plants.

Although variants exist, the basic unit shown in Figure 1.31 comprises sequences of narrow vertical chambers lined on both sides by filter cloths. The chambers, formed between hollow frames and flat filter plates or between adjacent recessed filter plates, allow for filter cake formations as well as washing and gas-blown deliquoring operations. Suspension is fed to the square, rectangular or circular chambers through a variety of plate porting... 

The device described by Wieland and Determann [756] for gradient elution TLC (Fig. 44) appears very convenient and capable of extension. The gradient is produced here by running the liquid to be added from a burette or measuring pump through a capillary (3) into the circular chamber (6 cm diameter) where it is then mixed with the existing... 

Many mechanically tunable microlenses are designed as circular chambers covered by thin flexible membranes. The membrane deforms when pressure is applied to the lens liquid through external actuation. In addihon, some microlenses are formed through air-liquid or liquid-liquid interfaces (immiscible, with different refractive indices). These interfaces may also be varied by applying pressure that adjusts the radii of curvatures of the spherical membranes in air-liquid devices and the focal lengths of the microlenses formed via liquid-liquid interfaces. 

Unlike the designs with rectangular lens expanding chambers discussed above. Song et al. proposed a design with a circular chamber to realize a perfect lens profile [16]. They presented a mathematical model to describe the relationship between the lens shape and flow rate. Their circular chamber is shown in Figure 7.12 [16]. The relationship between the flow rate ratio and focal length of the symmetrical double convex optofluidic lens was ... 

Li et al. presented a similar design of a circular chamber for lens curvature, adjusted by the combined effects of pressure and electro-osmosis [17]. Figure 7.14 shows the concept. Two cladding streams (fluid 1 and fluid 3) were electrically conducting with high electro-osmotic mobility the core stream (core fluid 2) was non-conducting with low electro-osmotic mobility.

Li s group [17] used aqueous sodium chloride (NaCl) solution (7 x 10 M) as the cladding liquid. Figure 7.15 demonstrates the interface shapes under different voltages. The measured interface shapes agreed wifh fhe calculated curves, confirming fhaf fhe inferface shapes in the circular chamber were optically smooth arcs. The results indicate that the combined effects of hydrodynamics and electro-osmosis may be used to control and tune optofluidic lenses. 

In column RPC (Figure 14), there is no vapor space (75). The stationary phase is placed in a closed circular chamber (column), and the flow is accelerated linearly by centrifugal force. The volume of stationary phase remains constant along the separation distance, hence the name column RPC. Since it is a closed system, there is no vapor space and any stationary phase of fine particle size may be used with or without binder. The rotating planar column has a special geometric design, which may be described by the function ...
