不可压纳维-斯托克斯方程的一个新的守恒能量

A New Conserved Energy for Incompressible Navier-Stokes Equations

Manuel García-Casado

摘要:

不可压纳维-斯托克斯方程中的压力条件引起总能量守恒。进入一个体积的能量率与从该体积出来的能量率是相同的。适当地选择压力可以抵消粘性项的能量耗散,从而保持总能量。因此,这防止了给定体积的流体中的动能爆炸。

英文摘要:

Pressure conditions in incompressible Navier-Stokes equations give rise to conservation of total energy. The energy rate getting into a volume is the same energy rate that gets out from it. Suitable choice of pressure counteracts energy disipation of viscosity term in such a way that total energy is preserved. As consequence, this prevents kinetic energy blow-up in a given volume of the fluid.
