Dean flow as a static mixer The use of the fluid inertia across a curved channel can create turbulence. The flow of fluids in the meandering channels undergoes mixing due to the inertia of the fluid in the flow direction. An example is shown in Figure II.6, while the Dean number is defined in the side bar. 

One stream is split into two curved sub-streams which simply merge and then instantly split again [143], The mixing is performed by several crosses in a row which are connected, with two channels for inlet and two for outlet. This process is repeated many rimes. Typical dimensions are not given and the fabrication is also not specified. Since no testing is reported, which is not surprising for an industrial proprietary method, no further information on this mixer is given below. 

Examples of the frequency-temperature curves for a bare device are given In Figure 2. Channel 1 and channel 2 refer to the two delay lines of the dual device. When used as a sensor, channel 1 would be coated and channel 2 would remain uncoated to act as a reference. The difference curve Is the output from the mixer, and represents the frequency difference between the two delay lines. 

Fig. 5.9.1 A spectmm of the R(ll) line of ethane on Jupiter recorded with a CO2 laser infrared heterodyne spectrometer. LO marks the frequency of the laser local oscillator. The observed 25 MHz spectmm (histogram) was detected with a 64-channel radio frequency receiver at the output of the infrared detector mixer. The dashed and solid curves are calculations of the line shape (Kostiuk et al, 1987).
