Name the form of mechanical energy, which is put to use for doing work. View Solution What are the two forms of cnidarian? How are they similar/ different? View Solution For a satellite moving in a circular orbit around the earth, the ratio of its total mechanical energy to kinetic energy...
In fact, it appears that for systems and processes with more than one utility (mainly mechanical or electrical power), energy conservation (First Law) is limited for representing their efficiency. Consequently, exergy analysis combining the First and Second Law seems essential for optimization of ...
Unconventional shale resources have become an integrated part of the energy chain largely in the last decade (Khan, 2017; Raza et al., 2015; De Silva et al., 2015). Successful production has been achieved from shale gas and shale oil reservoirs by technologies such as directional drilling and...
The study shows that the energy harvesting efficiency can be increased by up to 50% for a particular reduced velocity. Introduction Flow-induced vibrations phenomena (FIV) cover a comprehensive class of generally non-linear problems that lead to self-excited oscillations. Examples of FIV phenomena ...
TiHx and YHx: Two Distinct Examples for Diffusion in a Concentrated Lattice Gas The self-diffusion coefficient of hydrogen in the dihydrides TiHand YHwas investigated by neutron spectroscopy (1.59< x<2.09, 350degC< T<950degC). The two hydrides differ in that hydrogen in TiHoccupies solely ...
Increasing the energy consumption in pumps and obstructing the two-phase flow system are well-known examples regarding the destructive influences of high pressure drop inside channels11,12,13. Consequently, the optimal design of heat exchangers necessitates comprehensive predictive tools for pressure drop...
superior conductivity, some of 2D materials can function as the electrode to realize efficient charge collection [59,60]. Moreover, 2D materials possess excellent chemical and mechanical stability with high compactness, which render them resistant to moisture, oxygen, ion migration, and metal ...
Examples of 2D Materials Graphene was the first ‘modern’ 2D material to be isolated in 2004 [1]. Since then, there have been literally hundreds of other examples [2] along with other graphene materials, with an extensive range of properties. Below are several that are being actively researc...
The exploitation of both conventional and unconventional hydrocarbons may lead to still not well-known environmental consequences such as ground deformation and induced/triggered seismicity. Identifying and characterizing these effects is fundamental for
Examples Asynchronous Machine Scalar Control Control the rotor speed in an asynchronous machine (ASM) drive using the scalar V/f control method. The converter transforms a reference speed to a reference electrical frequency. The controller generates reference voltages from the reference frequency by ...
