Specific loss power

The energy absorbed by the magnetic particles under an applied external AC magnetic field is described by the specific absorption rate [SAR the term specific loss power (SEP) may also be used in some cases]. The SAR can be determined as ...

To analyze the energy absorption by the material and the subsequent heat transference to the media by the magnetic moment rotation under an AMF, the specific absorption rate (SAR) or specific loss power (SLP) can be determined ... 

The study carried out by Geisler et al. [152], which considered the dimensioning of the specific stirrer power per unit mass of the suspension e = FlpV, indicated the paramount importance of the D/dp parameter. In industrially-sized tanks (D/dp > 500) this quantity consists of two sum terms from an Ejs, which is required for maintaining that vertical flow rate n>t, which is equal to the terminal sinking velocity of the particle swarm Wss, and from the term edre, which covers the frictional losses of the flow upon reversal of the flow direction ... 

The boundaries of the FTA To demonstrate the concepts of this chapter, the FTAs drawn will not explore the interfaces to the original aircraft systems further than top-level failure modes of the inputs. Take power, for instance, where basic events will be defined for loss of power from the specific aircraft power bus where the power is sought (such as loss of Main DC). These data are typically available from aircraft FMEA or can also be obtained from FRACAS data for in-service aircraft with a statistically significant amount of in-service reliability data. 

Table 1 Comparison of heating parameters of iron oxide nanoparticles formed in the presence of tiopronin with Resovist and Nanomag 100 nm when placed in an AC magnetic field on a MACH system. Specific absorption rate (SAR) and intrinsic loss power (ILP) are compared for all 3 samples. Adapted from Refwith permission of The Royal Society of Chemistry.

From equation 60 one can obtain a theoretical power requirement of about 900 kWh/SWU for uranium isotope separation assuming a reasonable operating temperature. A comparison of this number with the specific power requirements of the United States (2433 kWh/SWU) or Eurodif plants (2538 kWh/SWU) indicates that real gaseous diffusion plants have an efficiency of about 37%. This represents not only the barrier efficiency, the value of which has not been reported, but also electrical distribution losses, motor and compressor efficiencies, and frictional losses in the process gas flow. 

The power rating of the driver for the impeller has to exceed the power dissipation to the fluid because of driver, seal, and bearing losses. Unless specific data are... 

The ESDs were then translated into associated event trees. A generic event tree was developed for all initiators not involving LOCA. The generic transient event tree for each category of the transient initiators and loss of offsite power were specialized by the impact of the initiators on the safety and support systems, from the success criteria of the mitigating systems, and the initiator-specific human actions which were modeled in the fault trees.
