Temperature profiles are calculated for laminar flow in a slit with electrical heat generation. The elliptic form of the thermal energy equation is sol which has an isothermal lower surface and an adiabatic upper surface. Our results show that a thermal inversion appears in the entrance region of...
Brushless DC motor [19,46,108,132,133] Multiple DC coils Permanent magnet Complex Less suitable for generation Switched-reluctance machine (SRM) [17,134] Multiple DC coils Soft magnetic material (reluctance) Complex Good high-speed and high-heat performance Lightweight and efficient power conve...
equation (Supplementary Fig.7e). In the latter robustness test, I take electricity prices to be exogenous, following the Energy Market Authority’s policy of updating tariffs quarterly to reflect changes in the cost of power generation50. Results are similar if instead I assume electricity prices ...
Stroke volume was assessed using cresyl violet staining 5 weeks after stroke as described previously68. Serial slices were taken 400 µm apart from the genu of the corpus collosum to the splenium. Areas were calculated using the following equation\(\frac{{Area}\;{Contalateral\,-\,Areal}...
7A. An Equation for the linear approximation is: S'=a(T'-T1)+b Eq. (2) where: a: is a slope which represents a derivative, dS/dt; b: is a value of S' at a time T1 of a first sample in the array; and T1 : is a time corresponding to the first sample in the array...
In this implementation, equation 4 can take precedence over equations 1 and 2 in determining the amplitude for the regulated output current IOUT(N). For example, if the electronic device function 416 requires only 10 mA and IOUT(N)=k(N) * (VIN−VOUT(N))=50 mA, then the additional ...
DETERMINATION OF EXPERIMENTAL MODEL BY EXPERIMENTAL DATA The correlating equation of the demulsification kinetics was derived as follows by summarizing the experimental results obtained in the preceding section. The mathematical calculations were performed by a combination of regression & Mont Carlo techniques...
The electron mobility is defined by the equation:vd=μEwhere vd is the charge carrier drift speed and E is the magnitude of the electric field applied to the material, and μ is the charge carrier mobility ((m/s)/(V/m) = m2/(V·s)). Both electron and hole mobilities are positive...
According to the differential form of Joule law, density of exudated heat p [W/m3] is electrical energy that is converted into a heat per unit time and per unit volume of substance: p = E2/ρ = σE2. From this equation, it is possible to move on to formulas for conductance G [S...
Equation (2) is the fitting equation of the Cu-Al2O3/30Mo/3SiC composite, and equation (3) is that of the 0.5Y2O3/Cu-Al2O3/30Mo/3SiC composite. It can be seen from the above equations that under the condition of 25 V, DC and 30 A, when the arc duration is greater than...
