The energy possessed by virtue of speed is called the kinetic energy. The energy due to the position of an object in an external field is called the potential energy. If energy is stored in (the internal electromagnetic fields of) a chemical, then it is called che...
Energy conservation is the principle by which the energy remains conserved during the process and is converted into one form into another, for example, the potential energy stored within the system can be converted into the kinetic energy when an object placed at some height is all...
aFor example, Fig. 7 shows that the combustion increases the flow kinetic energy at small scales (or high wavenumbers of energy spectrum), which is understandable since the heat release is confined to narrow reaction zone. 例如。 7表示,燃烧增加流程动能在小规模 (或能谱高wavenumbers),是可理解的...
