The work deals with upgrading of the temperature mode control in residential accommodation with electric heating due to transition from simple control systems to adaptive self-adjusting systems. Essential shortcomings of widespread on-off relays and other types of regulators are noted. The thermal balance of accommodation at the air heating stage from the initial to the set value is considered. The...
The article describes the principle of the simulation of microwave drying of dielectrics by the method of equivalent circuits. The mathematical model of the kinetics of the energy and mass transfer in the microwave drying of dielectrics was described. The equivalent circuits simulating the heat and mass transfer was shows. The mathematical simulation results of microwave drying of wood in periodic...
A 8-mm extended interaction klystron with a sheet electron beam and a modulator was developed. The klystron operates at cathode voltage 10 kV and cathode current 2,6 A. Mathematical simulation methods and computer codes MEMFIS (electrodynamics system), CST Particle Studio (electron gun, interaction processes, collector) and Ansys Maxwell (magnetic focusing system) were used in the development process...
A class of research, which explores energy saving via the accuracy-performance tradeoff ability of applications with soft outputs, is emerging. Many such applications implement various notions of precision improvement in their iterative computations and output approximated results. Computing more precisely often requires greater computational effort, hence there is a tradeoff space between precision...
Acoustic field dynamics is one of the intrinsic determinations of the temporal characteristics of phase conjugate waves in Brillouin-enhanced four-wave mixing (BEFWM). Theoretical and experimental research illustrate that the fundamental origination of temporal modulations in the phase conjugate wave of BEFWM is perhaps the unsteady-state distribution and fluctuations of the acoustic wave.
In this paper, a novel flux-switching permanent magnet (FSPM) linear generator is proposed for wave energy extraction. The linear generator is analyzed by using 2D finite element method (FEM) to investigate the electromagnetic characteristics. The result shows that the proposed generator has advantage of the voltage waveform by reducing the cogging effect. The computational results are verified by...
