Manufactured solutions are used for the numerical verification of Dirichlet, Neumann, and Robin boundary conditions, imposed through IBM. The proposed method is applied for solving problems involving thermal energy transfer for natural convection in an annulus between horizontal concentric cylinders. Results...
However, the imbalance between the availability of solar energy and the demand for solar thermal power is considerably high, and can be mitigated by solar thermal energy storage [6], [7]. Currently, there are three main types of thermal energy storage: sensible heat storage, latent heat ...
We anticipate that the fact that the Landauer limit in Fig.2is independent of the frequency (processor speed) is suspicious because the process of thermalization (the change from a non-equilibrium to an equilibrium thermodynamic state) is a dynamical process...
In case power losses are important for efficiency or thermal management of the power semiconductors, the PWM strategy can also play a role in losses reduction, as discussed in the next section. Discontinuous PWM A final example of PWM strategy is the discontinuous PWM (DPWM) that aims at ...
of both as-deposited and freestanding samples is plotted against the injected current density (Fig.2d). Interestingly, almost identical CIDWM behaviours are observed before and after the transfer process, with the only difference in the high-current-density region where the thermal nucleation of ...
FNF enables us to disaggregate system-on-chip devices further without crossing the thermal limits of the SiP and helping the key performance indicators (KPIs), including power-performance-area of the product. At 9 µm, the max frequency of 4 GT s−1has been assumed (in accordance...
which has a great effect on storing and delivering these energy resources [3,4]. So far, lithium ion batteries (LIBs), as a representative energy storage technology, have been widely explored for portable devices, electrical vehicles, and large-grid EESs because of high energy density and stabl...
Temporal and spatial presentations of biological cues are critical for tissue engineering. There is a great need in improving the incorporation of bioagent(s) (specifically growth factor(s) [GF(s)]...
Nanofluid heat transfer coefficient thermal conductivity heat transfer enhancement 1. Introduction One of the most important topics for engineering study and research is heat transfer. It plays an important role in power production, air conditioning, electronic components, transportation and many other appl...
Implantable and injectable scaffolds or gels have some common regulatable physicochemical properties, mainly containing hydrophilicity, electric charge, mechanical strength, thermal stability, biodegradation rate, and controlled payload release which can be adjusted by the types, quantity, ratios and ...
