A method is proposed to measure transverse blood flow by using photoacoustic Doppler broadening of bandwidth. By measuring bovine flowing through a plastic tube, the linear dependence on speed was validated. The microvasculature in mouse ear and chicken embryo (stage 16) also studied.
The working temperature of an LED chip has a great influence on its photoelectric properties. It is urgently necessary to develop adaptive cooling device for LEDs' heat management. This paper proposes "multi-needle-to-mesh" ionic wind generator enhanced transfer in high-power LEDs (HPLED). Experiments were conducted evaluate the performance HPLEDs under multiple conditions. electric field intensity (EFI) distribution, charge density, and dynamic pressure measured. We also investigated...
To enhance the heat dissipation of high-power light-emitting diodes (LEDs), corona wind based on discharge was promoted. In this paper, we aimed at reinforcing intensity by modifying needle electrode with graphene solution. explore differences in graphene-coated and original bare electrical characteristics, wind, LED dissipation, a cooling system thermal test were built for experimental study. The results showed that could produce lower voltage. addition, current is higher than under same...
Facing the unbalanced development of resource distribution and productivity, China needs long-distance power transmission distribution. The will lead to a lot loss in process transmission. In order achieve long-distance, large capacity, low transmission, it is necessary build UHV transformation lines grid for cross regional allocation. As key equipment transformation, bushing plays very important role line. However, due working electric field long time, reduction failure rate smooth...
The contact force between particles is analysed in this paper. Firstly, theoretical analysis carried out based on the Hertz–Mindlin (no slip) model. Secondly, normal and tangential are, respectively, simulated single/double‐flight screw feeders with discharging device at three rotating speeds (60 rpm, 90 120 rpm) using different diameter (3 mm, 5 7 mm) by extended distinct element method (EDEM) software. Finally, simulation results show that particle has biggest impact average feeding...
In order to detect the underground medium with large depth, transmitter of electromagnetic sounding instrument has higher and power voltage. A novel voltage equalizing strategy for cascaded constant current supply using in was proposed this paper. The topology two isolated full‐bridge AC/DC converters, which had same input source were connected series on output side. mathematical model based state space average method analyzed. After simplifying circuit, equation used describe circuit model....
As the key equipment of UHV transmission and transformation line, bushing needs to carry ultra-high voltage large current power system at same time. When operating temperature is too high, operation failure rate will increase significantly, which affect stability safety line. Therefore, it particularly important analyze field characteristics bushing. This paper takes as research object. The finite element software used calculate electro thermal coupling. three-dimensional distribution are...
This paper does research on a new bushing structure as solution to the shortcomings of traditional transformer structures. Oil-paper has risk oil leakage, explosion and combustion. Epoxy resin impregnated (RIP) composite disadvantages high cost, complex structure, process difficult heat dissipation.
