Modeling helicity dissipation-rate equation

Nobumitsu Yokoi

摘要:

本文利用非均匀湍流的统计解析闭合理论,导出了湍流螺旋度耗散率的输运方程。结果表明,螺旋度标度的螺旋度和它的耗散率之间的代数关系的假设导致的湍流螺旋度耗散率的传输方程,而不诉诸于一个启发式的建模。

英文摘要:

Transport equation of the dissipation rate of turbulent helicity is derived with the aid of a statistical analytical closure theory of inhomogeneous turbulence. It is shown that an assumption on the helicity scaling with an algebraic relationship between the helicity and its dissipation rate leads to the transport equation of the turbulent helicity dissipation rate without resorting to a heuristic modeling.
