gradient tensor 中文意思是什麼
gradient tensor
解釋
梯度張量-
Maximum - norm superapproximation of the gradient for the tensor - product quadratic rectangular parallelepiped finite element
張量積二次長方體有限元梯度最大模的超逼近 -
If the two - equation turbulence models employ a linear relationship between the reynolds stress and the mean strain - rate tensors, this relationship is known as the generalized boussinesq model, the two - equation models can be extended for a wider range of applicability by developing more advanced nonlinear algebraic relations between the stress tensor and the mean - velocity gradient and the turbulent scales, this is known as explicit algebraic stress models ( easm )
另一個是構成模型,即決定應力張量、應變率張量和兩個湍流尺度因子之間的函數關系式,它決定了雷諾應力。如果構成模型是線性的,則為boussinesq渦粘模型( evm ) ,如果構成模型是非線性的代數關系式,則為顯式代數應力模型( easm ) 。
