The behaviour of a thin film of an organic solvent on the walls of the extraction coil in a continuous liquid-liquid extraction flow system was studied using a computer-controlled fast-recording on-tube photometric detection system (approx. 3 ms time resolution). A single-loop injector was employed to introduce precise, reproducible volumes (Sr < 2%) of one phase into the continuous stream of the other as a segmented volume standard. The film thickness Df, ranging from 1 to 20 μm for a 0.7 mm teflon tube, was calculated from the segment lengthening at a different chloroform flow rates and was found to obey a polynominal dependence on the linear flow rate, df = f(uα), where α < 1.

Power Fluctuations

This paper discusses a structural property for a power system to continue a safe operation under power fluctuation caused by fluctuating power sources and loads. Concerns over global climate change and gas emissions have motivated development and integration of renewable energy sources such as wind and solar to fulfill power demand. The energy generated from these sources exhibits fluctuations and uncertainty which is uncontrollable. In addition, the power fluctuations caused by power loads also have the same consequences on power system. To mitigate the effects of uncontrollable power fluctuations, a power flow control is presented which allocates power levels for controllable power sources and loads and connections between power devices. One basic function for the power flow control is to balance the generated power with the power demand. However, due to the structural limitations, i.e., the power level limitations of controllable sources and loads and the limitation of power flow channels, the power balance may not be achieved. This paper proposes two theorems about the structural conditions for a power system to have a feasible solution which achieves the power balance between power sources and power loads. The discussions in this paper will provide a solid theoretical background for designing a power flow system which proves robustness against fluctuations caused by fluctuating power devices.
