By taking up to 500 images per second, RUBIs cameras can create a three-dimensional representation of the bubble shapes and analyse the temperature distribution on the heater, enabling the scientists to precisely determine evaporation conditions and heat flux densities. The boiling process can be systematically influenced using a high-voltage electrode (up to 15,000 volts) and an adjustable convection loop.
Magnet height, stator outer diameter and flux densities, slot opening, core length, and rotor outer diameter parameters are defined to be optimized as given below;
Among the experiments, are a load test of a direct-current series motor, a back-to-back test on two identical transformers (the Sumpnor Test), to measure the iron loss at different flux densities with a Lloyd Fisher magnetic square, to plot magnetization characteristics and load characteristics of metadyne generators, and calibrating a wattmeter and ammeter by Crompton's potentiometer.
The flux densities in the tooth and yoke regions are then calculated by dividing the corresponding fluxes with their cross sectional areas.
From a physics viewpoint, the flux densities observed in radio astronomy are spectral irradiances; consequently, they are given in power per unit bandwidth and per unit equivalent collecting area of the antenna.
The heat flux densities have been analyzed at 6000 RPM as well as at 9500 RPM.
The equations for the flux densities resulting from this current sheet are described in [13].
4(a) diverges quickly near the transmitting coil, and the flux densities near the receiving coil fall in the range between 1.95e-7 and 2.08e-7 T.
Theoretical studies suggest that constant magnetic flux densities in the range of 25-100 Tesla would be required to affect ionic currents of nerve processes [7],[8].
The proposed test frame can be used to measure the electromagnetic characteristics of various thicknesses of laminated silicon-steel sheet at high frequencies (50-5,000 Hz) and high magnetic flux densities (0.2-1.8T).
It requires flux densities in the neighborhood of 1kW/[cm.sup.2] or less and pulse durations of about 1 ms or longer.
The use of field expressions corresponding to the core and the clad sections of microstructured guide, as represented in (3a), (3b), (3c), (3d), (3e), and (3f) and (5a), (5b), (5c), (5d), (5e), and (5f), respectively, would provide the energy flux densities [23] in the two sections of guide.
