The base flow is computed using a NavierStokes algorithm and the stability analysis is performed via the OrrSommerfeld equation. The wake is found to be convectively unstable and the frequency of the most unstable mode fw is determined. The case when fw ~ f coincides with maximum energy ...
In equation (1), VQ,rel and Q‾ denote the relative variance and the average of the generated electric charge measured repeatedly during a constant integration time. The mean energy required to produce an ion pair, We, corresponds to the value for high-energy electrons. It is defined as ...
Rearrange the equation to solve for frequency: ν = c/λ Next, replace frequency in the first equation with c/λ to get a formula you can use: E = hν E = hc/λ In other words, the energy of a photo is directly proportional to its frequency and inversely proportional to its wavelen...
Energy has some meaning to everyone. A person often does not have energy following a bout with a cold. Concerns about depletion of our energy resources, solar energy, wind energy, and nuclear energy are common topics in newspapers and on television. Although energy has several meanings, in a...
SummaryBackground & aims When individual energy requirements of adult patients cannot be measured by indirect calorimetry, they have to be predicted with an equation. The aim of this study was to analyze which resting energy expenditure (REE) predictive equation was the best alternative to indi...

New general decay results for a Moore–Gibson–Thompson equation with memory In this paper, we consider the Moore–Gibson–Thompson equation with a memory term in the subcritical case, which arises in high-frequency ultrasound appli... W Liu,Z Chen,D Chen - 《Applicable Analysis》 被引量: ...
The turbine's height from the ground, where the measurement is conducted, has a profound influence on the wind source's power output. Correcting the height to an optimal level is feasible during installation, facilitated by a height adjustment equation. Calculating the wind speed at a fixed heig...
Equation (5) is the transfer function of the virtual controller. The parameters of the controller are set according to the results of the improved whale algorithm to achieve the optimal control performance. The issue of frequency control in power systems has been studied, and the object of VSG...
so that this term is a transport term. The third item on the right-hand side of this equation is the work done by the pressure per unit mass of fluid per unit time. The fourth item∂ui∂xiis the volume expansion rate, whose product with pressurePrepresents the expansion work. The ...
