Evaluation Method for Pressure Loss using Energy Dissipation

SAE International Journal of Passenger Cars - Mechanical Systems, 2008
<div class="htmlview paragraph">In order to make more effective use of simulation, a new evaluation method on pressure loss has been developed. Using this method, the location and amount of pressure loss is clarified. As a result, enormous simulation data have been used effectively.

Dissipative energy losses in ferromagnetic generator of frequency

Digest of Technical Papers. 12th IEEE International Pulsed Power Conference. (Cat. No.99CH36358), 2003
Ferromagnetic generators are devices, which use shock-induced demagnetisation of matter in order to receive a current pulse. During shock wave movement through the working body of ferromagnetic matter a part of the shock wave energy can also be converted into microwave energy.

Determination of the Dissipative Loss in Low-Loss Two-Ports

Conference on Precision Electromagnetic Measurements, 1988
The dissipative loss of a reciprocal two-port can be determined from its input reflection coefficients measured while terminating the output with load, short and open circuits, and sliding short. The paper presents a statistical approach applied to minimize random errors of the loss determination.

Head loss coefficient of orifice plate energy dissipator

Journal of Hydraulic Research, 2010
Orifice plates as an effective energy dissipator have been used in hydropower projects. The head loss coefficient, relating directly to the energy dissipation ratio, is an important index of these elements. This coefficient and parameters such as the contraction ratio of the orifice plate diameter and the flood discharge tunnel diameter, the ratio of ...

Magnetic hysteresis and dissipative losses in superconducting films

Technical Physics Letters, 1997
An analysis is made of the response of thin-film superconductors to an oscillating magnetic field. The field strengths for defreezing and expulsion of the flux are determined. A hysteresis curve is plotted for the sample over the entire oscillation cycle of the magnetic field.

Characterization of dissipative losses in microwave circuits

Microwave and Optical Technology Letters, 1994
AbstractThe analytical expression for the fractional power dissipated by a microwave circuit is derived in terms of the scattering parameters. Consideration is given to both complex and real port reference impedances. Theoretical values of fractional dissipated power, computed using a full‐wave analysis technique, are compared to experimentally ...

Dissipation Loss in Multiple-Coupled-Resonator Filters

Proceedings of the IRE, 1959
This paper examines the effect of dissipation on the response of multiple-coupled-resonator filters designed from lossless prototype low-pass filters. A simple approximate formula makes possible the computation of center-frequency loss in terms of bandwidth, unloaded Q of the resonators, and the parameters of the prototype filter.

Irreversibility curve and dissipative losses in YBaCO films

Low Temperature Physics, 1995
The susceptibility of polycrystalline and epitaxial YBCO films in weak exciting magnetic fields Hac = (0.1–1000) mOe is investigated by using the inductive technique. The behavior of their irreversibility curves (1-Tm/Tc) and the peak of dissipative losses is studied. Two characteristic fields H1* and H2* are observed for which the curves (1-Tm/Tc)(Hac)

DECAY PROPERTY OF REGULARITY-LOSS TYPE FOR DISSIPATIVE TIMOSHENKO SYSTEM

Mathematical Models and Methods in Applied Sciences, 2008
We study the decay property of the dissipative Timoshenko system in the one-dimensional whole space. We derive the L2 decay estimates of solutions in a general situation and observe that this decay structure is of the regularity-loss type. Also, we give a refinement of these decay estimates for some special initial data.
